advance for morphological characters in Brassica carinata L. A total of 22
genotypes comprised of six parental lines and their 16 bulk F 2 populations
were evaluated in a randomized complete block design with three
replications at The University of Agriculture Peshawar during 2013-14. Data
were recorded on days to 50% flowering, primary branches plant -1 , main
raceme length, pods on main raceme, pod length, number of seeds pod -1 ,
100-seed weight, and seed yield plant -1 . Significant genetic differences were
observed for all the traits studied. Among parental lines, C-93 performed
better for primary branches plant -1 (11 branches), main raceme length
(59.57 cm), pods on main raceme -1 (33 pods), and seeds pod -1 (15 seeds), C-
95 for pod length (4.04 cm) and seed yield plant -1 (12.26 g). Among F 2
populations, C-97 x C-88 performed better for main raceme length (73.20
cm), pods on main raceme (41 pods), C-88 x C-93 for pod length (4.95 cm),
seeds pod -1 (18 seeds), and seed yield plant -1 (14.71 g). Moderate (30 < h 2
≤ 60) to high (h 2 > 60) broad-sense heritability was observed for all
morphological traits with maximum genetic advance, hence indicated that
selection could be effective in the early generation for the improvements of
these studied traits. Generally, cross combinations C-88 x C-93, C-97 x C-95,
C-90 x C-93, and C-97 x C-88 performed better than their parental lines for
morphological (primary branches plant -1 , seeds pod -1 , and seed yield plant -1 )
traits and could be exploited for varietal development in future brassica
breeding programs.

The genetic basis for different brassica genotypes in terms of biochemical characteristics is important for the planning of effective breeding strategies. The present research was conducted to determine heritability, genetic advance and coefficient of correlation for biochemical traits in rapeseed. Breeding material comprising 10 parental lines and their 21 F3 populations was evaluated in the 2013-2014 at The University of Agriculture of Peshawar-Pakistan in a randomized complete block design with three replicates. For all studied traits, substantial differences were found among genotypes, parents, and F3 populations. Similarly, significant differences for all the studied traits with the exception of protein and glucosinolates have been recorded for parent vs. F3 populations. In most F3 populations, the heritability estimates associated with the maximum genetic advance for oil content, protein content, linolenic acid, erucic acid, and oleic acid were low or moderate. In comparison, moderate to high heritability coupled with maximum genetic advance, have been observed for glucosinolates for most F3 cross combinations. These findings show that selection in the early generation may be helpful in improving these characters. Oil content showed a negative and highly significant correlation with glucosinolate (rp=-0.50) and linolenic acid (rp=-0.57), so priority should be given to these traits to improve oil content. CA2 x DH5, DH7, and CA2 x DH7 performed better for oil content, protein content, and oleic acid, respectively, while DH2, DH5, and CA2 x DH8 showed better results for glucosinolates, linolenic acid, and erucic acid, respectively. These genotypes could be further utilized in rapeseed breeding programs., 2020. Genetic analysis of biochemical traits in F3 populations of rapeseed (Brassica napus L.). Asian J. Agric. Biol. 8(4): 491-500.

A set of 19 wheat genotypes comprised of seven parents and 12 F2 populations were evaluated at The University of Agriculture-Peshawar during 2013-14 in a randomized complete block design (RCBD) with three replications. Data were recorded on days to 50% heading, days to maturity, plant height, flag leaf area, productive tillers plant-1 , spike length, biological yield plant-1 , spikelet spike-1 , grains spike-1 , grain yield plant-1 , and harvest index. Analysis of variance showed significant differences among genotypes, parents, and F2 populations for all the studied traits while parent vs. F2 population also revealed significant genetic variability for all the studied traits except plant height, spike length, and spikelet spike-1. Low to moderate broad-sense heritability coupled with low genetic advance was observed for almost all the traits studied. Among Parents, Janbaz was the highest in productive tillers plant-1 , spikelet spike-1 , grains spike-1 , and grain yield plant-1. Among F2 population, Saleem-2000 × Barsat had the earliest 50% heading and maturity, Saleem-2000 × Watan, Tatara × Barsat, AUP-5008 × Fakhre Sarhad, and Janbaz × Barsat showed the shortest plant, large flag leaf area, long spikes, more productive tillers plant-1 , grain yield plant-1 , harvest index, biological yield plant-1 , and spikelet spike-1. Saleem-2000 × Watan, Tatara × Barsat, AUP-5008 × Fakhre Sarhad and Janbaz × Barsat having a better performance for most of the traits and hence could be utilized in future wheat breeding programs.

a set of eight brassica genotypes in a randomized complete block design with three replications at The University of
Agriculture Peshawar, during 2011-12 cropping season. Significant genetic variability was recorded among genotypes
for plant height, pods main receme -1 , pod length, seed yield plant -1 , 1000-seed weight, seeds pod -1 , oil content, protein
content, glucosinolate content, erucic acid content, oleic acid content and linolenic acid content except for primary
branch plant -1 and pods plant -1 which showed non-significant differences. Genotypes, AUP-401, AUP-402, AUP-404
and AUP-407 showed potential performance for glucosinolate content (55.1 µmol g -1 ), seed yield plant -1 (23.93 g), pods
plant -1 (268.83), protein contents (21.1 %), erucic acid contents (42.7 %) and oil contents (53.3 %). Seed yield plant -1
was taken as a dependent variable to study the effects of many morphological yield traits on it. Branches plant -1 , pods
main raceme -1 , pods plant -1, and seed pod -1 showed a positive effect on seed yield plant -1 , while 1000-seed weight, pod
length, and plant height showed a negative effect on seed yield plant -1 . Seed yield plant -1 as an independent variable
showed a negative effect on oil content. Protein content as an independent variable showed a positive effect on erucic
acid content, while oil contents as independent variables show a negative effect on protein contents, respectively. The
developed germplasm could be used in the upcoming brassica breeding programs to release high yielding, disease
resistance, stress tolerance, and insect resistance varieties, which will eventually upsurge the productivity and decrease
the gap between demand and domestic production of the brassica crop

coefficient in a set of 31 rapeseed genotypes, comprised of 10 parental lines and their 21 F 3 populations. These
genotypes were evaluated in a randomized complete block design at The University of Agriculture-Peshawar-
Khyber Pakhtunkhwa-Pakistan with three repeats. Significant differences were recorded for days to 50%
flowering, plant height, primary branches plant -1 , main raceme length, pods main raceme -1 , pod length, seeds
pod -1 , 1000-seed weight, seed yield plant -1 among genotypes, parents and F 3 population. Similarly, parents
vs. F 3 population also showed significant differences for all the studied traits except primary branches plant -1
and pods main raceme -1 , which revealed non-significant differences. Among parents DH4, DH5 performed
better for seed yield plant -1 (15.2 g), seeds pod -1 (23.7), respectively, while DH8 showed better performance
for pods main raceme -1 (76.6), pod length (7.7 cm) and 1000-seed weight (7.3 g). Cross combinations CA5
× DH6, CA5 × DH7, CA2 × DH7 and CA5 × DH3 showed potential performance for pods main raceme -1
(80.9), pod length (8.2 cm), seeds pod -1 (25.7), 1000-seed weight (7.8 g) and seed yield plant -1 (18.4 g). All
the studied traits showed moderate (>30%) to high (>60%) broad sense heritability coupled with maximum
genetic advance in F 3 populations, hence indicated that selection could be effective in the early generation
for the improvement of these traits. Correlation analysis indicated that flowering (r p =0.45), primary branches
plant -1 (r p =0.49), main raceme length (r p =0.41), seeds pod -1 (r p =0.41) and 1000-seed weight (r p =0.38) had
positive and significant association with seed yield plant -1 . Genotypes, DH4, DH5, DH8, CA5 × DH6, CA5
× DH7, CA5 × DH3, and CA2 × DH7 displayed well genetic potential for the majority of the traits hence
could be used in future rapeseed breeding programs

Research Institute, D.I. Khan, KP , Pakistan. The aims of the study were to screen out genetic variability among GSR
lines and to assess heritability and genetic advance and correlation between yield and related attributes. The experiment
was laid down in a randomized complete block design with three replications and data on eight production traits
were recorded and subjected to various statistical analysis. The results corresponding to analysis of variance revealed
significant (P ≤ 0.01) differences among GSR lines for all the studied traits. The presence of slightly higher phenotypic
coefficient of variation than genotypic coefficient of variation indicated the negligible influence of environment on
the expression of yield and its component traits. Similarly, the highest heritability (>60%) associated with genetic
advance were assessed for all the traits, except panicle length, indicating better scope for improvement of these traits
by an effective selection program. Correlation analysis revealed that paddy yield manifested significant correlation with
days to panicle emergence (r=0.57**), panicle length (r=0.53*) and number of filled grains panicle -1 (r=0.63*) hence,
ample importance should be given to these traits during selection.

mineralization and organic matter content in an alkaline calcareous soil by using soil samples collected from Malakandher
Farm at 0-20 cm depth, and analyzed for microbial activity, total mineral nitrogen, bacterial and fungal population
and organic matter content. The results showed that the rate of CO 2 evolution and cumulative CO 2 production were
higher in soils amended with elemental sulfur followed by sulfuric acid and gypsum treated soils. The microbial activity
decreased with incubation period in all treatments, and the microbial population was greatly affected by sulfur sources.
Generally, the bacterial population decreased in soils amended with elemental sulfur, but the population was higher
in soils amended with gypsum. Bacterial population was suppressed in soils treated with sulfuric acid. However, the
fungal population was higher in soils amended with sulfuric acids was less in soil amended with elemental sulfur. The
sulfur amendments promoted immobilization of N. The net N immobilized was higher in soil amended with gypsum
followed by soils amended with sulfuric acid and elemental sulfur. The percent organic matter was higher in soils
amended with gypsum and was decreased compared with that amended with elemental sulfur or sulfuric acid. These
results suggested that soil microbiological properties changed with sulfur amendments during laboratory incubation

Total of (10 desi and 10 kabuli) genotypes were grown in a randomized complete block design with three replications. Plant height showed positive and highly significant correlation with 100-seed weight, while negative and highly significant correlation recorded with seeds pod-1 and harvest index. Secondary branches exhibited positive significant association with pods plant-1 and 100-seed weight while negative significant interrelationship found with seeds pod-1 and harvest index. Pods plant-1 revealed negative significant association with seed yield (kg ha-1), seeds pod-1 and harvest index. Positive correlation of seeds pod-1 presented with harvest index. Highly significant and positive correlation of seed yield (kg ha-1) was observed with harvest index and seeds pod-1 , while significantly negative relationship observed with 100-seed weight. Harvest index and seeds pod-1 would be the appropriate selection criteria for better seed yield in chickpea.

Data were recorded on grain yield and other agronomic traits. Observations showed difference in half-sib families for studied traits. Among the 64 half-sib families, minimum days to 50% tasseling (51 d) were observed for HS-49 while maximum (57 d) for HS-63. Minimum days to 50% silking (56 d) were counted for HS-6 while maximum (63 d) for HS-23. Minimum days to 50% anthesis (55 d) were counted for HS-1 and HS-6 while maximum (62 d) for HS-23. Similarly, minimum ASI (-2 d) were observed in HS-1, HS-15, HS-16, HS-28 and HS-63 while maximum (2 d) in HS-48. Minimum (60 cm) ear height was recorded for HS-11 and maximum (93.5 cm) for HS-28. Minimum fresh ear weight (1.3 kg) was weighted for HS-17 while maximum (3.2 kg) for HS-21. Grain moisture was recorded minimum (19.35 %) for HS-19 and maximum (31.25%) for HS-2. HS-42 showed minimum (28 g) 100 kernel weight while HS-5 showed maximum (47 g). Grain yield was minimum (2323 kg ha-1) for HS-17 and maximum (5742 kg ha-1) for HS-21. Maximum heritability estimate (0.92) was recorded for fresh ear weight, while minimum (0.41) was observed for ear height.

Forty nine half-sib families derived from maize variety Sarhad White were used in the study. The experiment was laid out in 7×7 partial balance lattice design with two replications. Results indicated that the half-sib families were significantly different from one another for all the traits studied. Among the 49 half-sib families minimum days to 50% tasseling (50.0) were recorded for HS-32 while HS-48 showed maximum days to 50% tasseling (60.0). Minimum days to 50% silking (51.0) were observed for HS-08 while HS-48 showed maximum days to mid tasseling. Minimum plant height of 110.50 cm was recorded for HS-41 while HS-08 showed maximum plant height (160.60 cm), minimum ear height (40.70 cm) was recorded for HS-41 and maximum ear height (79.60 cm) for HS-48. Minimum grain moisture (14.0%) was recorded for HS-03 while maximum (30.60%) for HS-12. Minimum ear length (9.20 cm) was recorded for HS-41 while maximum (14.80 cm) was for HS-04. Minimum grain yield (3133.0 kg ha) was recorded for HS-43 1 while HS-06 showed maximum (7423.0 kg ha) grain yield. Maximum heritability estimate (0.84) was observed 1 100-kernal weight, while minimum (0.42) was observed for yield. Maximum correlation of yield was recorded with plant height and ear height. These results suggest that these half-sib families could be used as source of improved maize germplasm for developing maize genotypes with superior attributes.

In spring season, 18 three way cross hybrids were developed by crossing 18 elite inbred lines with three single cross hybrids in different combinations. In summer season, the crosses were evaluated along with commercial check hybrids. The experiment was conducted in a randomized complete block design with three replications. Data were recorded on plant height, ear height, cob length, kernel rows cob-1, 100-seed weight and grain yield. Hybrids showed highly significant differences for all traits studied except kernel rows cob-1. Maximum plant height was recorded for Ev3-157-5-4-2×P-30k08, while minimum plant height was attained by Pop 9804×Bemisal. Maximum ear height was recorded for Swajk-4-9×P-3025. Pop 9804×Bemisal exhibited minimum ear height. Percent heterosis for plant and ear height over checks showed positive and negative differences. Among the hybrids, maximum ear length was observed for Ev3-157-5-1-7-3-9-5×Bemisal, while minimum was recorded for Ev3-157-5-1-1-9-1× P-3025. Maximum number of kernel rows ear-l was detected for Ev3-157-5-1-1-9-1×P-30k08 and Pop9804×Bemisal, while minimum number of kernel rows ear-l was exhibited for Ev3-157-5-4-2×P-30k08 and Ev3-45-4-3-7-2-3-2×P-30k08. Maximum 100kernel weight was recorded for Ev3-120-2-3-2-1-2-1×P-30k08, while minimum 100-kernel weight was observed for Ev3-157-5-4-2×P-30k08. Highest yielding cross was Swajk-6-6-3-5-1×P-30k08, while lowest grain yield was observed for Ev3-157-5-4-2×P-30k08. The magnitude of heterosis for yield and yield contributing traits varied and showed significant as well as non significant estimates for various traits studied during investigation.

An experiment was performed at Malakandher Research Farm, The University of Agriculture, Peshawar during 2011-12 to evaluate 14 wheat advance lines with four cultivars i.e Atta-Habib, Siren, Pirsabak-2005 and Pirsabak-2008 used as checks under rainfed conditions. The experiment was not irrigated throughout the whole growing season. The experiment was laid out in a randomized complete block design (RCBD) with 3 replications. Each entry was planted in 03 rows, 03 meter long and 30 cm apart. To minimize environmental effects on the genotypes recommended cultural practices were applied same for all the treatments. Data were recorded on 6 parameters viz, days to maturity, spike length, spikelets spike -1 , grains spike -1 , spike weight and spike density. Highly significant differences were observed for all the parameters. Mean values for genotypes ranged between 161.3 to 167.3 for days to maturity, 9.57 to 12.86 cm for spike length, 15.13 to 19.93 for no. of spikelets per spike, 41.05 to 60.80 grains spike -1 , 2.47 to 3.61g for spike weight and 0.531 to 0.675 for spike density. Spike density was positive and highly significantly correlated with spike length, positive significant correlated with days to maturity, negative highly significantly correlated with spikelets spike -1 . Based on the results of this study MPT7 can be recommended to be used in further breeding programs as it has high spike length, spikelets spike -1 , grains spike -1 , spike weight and spike density.

Five chickpea populations, i.e. three parental and two F 3 populations (NDC-4-20-4, ICC-19181, NDC-5-S10, ICC-19181 x NDC-4-20-4, ICC-19181 x NDC-5-S-10) were evaluated for variability and interrelationship at Malakandher research farm, The University of Agriculture Peshawar during chickpea growing season 2011-12. Analysis of variance revealed promising differences (P≤0.01) among populations for pods ṗlant -1 , secondary branches plant -1 , seed yield plant -1 , days to flowering, harvest index, biological yield plant -1 and days to maturity. Furthermore, significant differences were shown for plant height, primary branches plant -1 and seed yield kg ha -1 . F 3 population of C 1 revealed maximum values for pod plant -1 , secondary branches plant -1 (14.87), seed yield plant -1 (19.66 g), biological yield plant -1 (36.91g) and harvest index (52.78 g). Whereas population of C 2 showed maximum values for days to flowering (141.33) and primary branches plant -1 (5.00). On the other hand, ICC-19181 showed minimum values for days to flowering (132), plant height (32.90 cm) and seed yield plant -1 (14.13 g). Correlation analysis showed highly significant and positive association of grain yield plant -1 with pods plant -1 , secondary branches plant -1 , biological yield plant -1 and harvest index while significant correlation with days to flowering, days to maturity whereas non-significant correlation was revealed for plant height and primary branches plant -1 . This study suggests that pods plant -1 , secondary branches plant -1 , seed yield plant -1 , biological yield plant -1 and harvest index are the key component in grain yield. C 1 (ICC-19181 x NDC-4-20-4) population can be used in future chickpea breeding programs for higher yield.

The current research work was planned to evaluate the genetic potential and traits association in 20 Desi and Kabuli chickpea genotypes (10 Desi and 10 Kabuli). The genetic materials were grown in a randomized complete block design (RCBD) with three replications. Data were collected on plant height (cm), secondary branches plant -1 , pods plant -1 , seed yield (kg ha -1 ), biological yield plot -1 and harvest index. Genotypes revealed significant differences for most of the traits which ranged from 63.66 to 105.28 cm for plant height, 8 to 18 for secondary branches plant -1 , 43 to 64 for pods plant -1 , 862 to 2481 kg for seed yield (kg ha -1 ), 1383 to 3576 g for biological yield plot -1 and 20 to 39% for harvest index. Mean squares showed highly significant differences (P≤0.05) for comparative performance of Kabuli and Desi genotypes. Mean value for seed yield (kg ha -1 ) of Kabuli genotypes was 1210.10 kg, which was comparatively less than mean value of Desi genotypes which was 1823.90 kg. Among Kabuli genotypes, analysis of variance (P≤0.05) showed significant differences for most of the traits. Genotype NKC-5-S14 showed minimum (861.60 kg ha -1 ) seed yield while maximum (1589.30 kg ha -1 ) seed yield was recorded for NKC-5-S16. Mean squares in Desi genotypes also revealed significant differences (P≤0.05) for most of the traits. Maximum (2481.3 kg ha -1 ) seed yield was given by genotype NIFA-2005, while minimum (1002.90 kg ha -1 ) seed yield was recorded for genotype SL-3-29. Broad sense heritability estimates for yield and yield components were moderate to high that ranged from 54% to 92%. Positively and highly significant association of seed yield was observed with biological yield plot -1 (r = 0.85**) and harvest index (r = 0.42**), while significantly negative correlation was observed with 100-seed weight (r = -0.26*). Biological yield plot -1 , harvest index would be the proper choice criteria for better seed yield in chickpea. Results showed that genotypes NIFA-2005, NDC-4-20-5, SL-3-64, NDC-4-20-4 and NKC-5-S16 performed better and could be utilized as a part of future breeding projects for the improvement of high yielding cultivars.

The aims of the study were to generate scientific information on nature and magnitude of genetic variability and relationship of yield and related attributes and to classify genotypes into distinct clusters on the basis of quantitative traits. Fourteen elite rice genotypes were evaluated following RCB design with three replications. There was significant (P ≤ 0.01) differences among genotypes for all the studied traits, except physiological maturity. The magnitudes of PCV and GCV were higher (>20%) in all the studied traits, except physiological maturity, reflecting wide spectrum of variability and offering greater opportunities for selection. Similarly, the magnitude of broad-sense heritability and genetic advance as percent of mean was moderate to high for majority of traits, indicating additive gene action in their inheritance hence, amenable for simple selection. Correlation analysis revealed that paddy yield manifested significantly positive correlation with physiological maturity (r = 0.46**) and negative correlation with 1000-grain weight (r = -0.30*). The dendrogram grouped 14 into four clusters. Cluster IV incorporated the highest number of genotypes, which also had highest cluster mean for paddy yield. Therefore, prominence should be given to genotypes aggregated in cluster IV that having high yield potentiality. Based on mean performance, Irrigated-04, E-93, E-94 and E-107 showed superiority in respect of paddy yield and some other traits, hence these lines could be recommended for varietal development.
