total of 11 SSR markers were used to characterize all Aus rice genotypes. Methods/Findings: All of them were polymorphic
showing different chromosome numbers. The number of alleles per locus varied from 3 alleles (RM234 and RM277)
to 15 alleles (RM493). A total number of 72 alleles were detected with an average number of 8.91 alleles per locus. The
polymorphic information content (PIC) values ranged from 0.19 (RM277) to 0.90 (RM493) with an average 0.70. The
highest PIC value was obtained in RM493 (0.89) followed by RM526 (0.85) and The highest genetic dissimilarity (1.00)
was found among the nineteen Aus genotypes combinations viz., Kalojira TAPL-68, Busmoti-sufoid, Hatisail, Sakharkhara,
Khasa, Black, Ukinmodhu, Fulkari, Porbotjira, Straw THPL-554, Kalonunia, China IRRI, Mehedhan, Tulsimoni, Meny,
Tilkapur, Nunia, Lalmota and Tapu. This material may be selected as potential parents for crop improvement for their
distinctive characters. Whereas lowest genetic dissimilarity was found between Chini sagor-1 vs Malshira and Kalijir TAPL-
74 vs Kalojira (0.18) followed by three other pairs (0.28). Application: The genetic distance-based results seen in the
Unweighted Pair Group Method of Arithmetic means (UPGMA) revealed six genetic groups. These landraces will be useful
for the selection of diverse parents, background selection during backcross breeding programs and assist in broadening
germplasm-based rice breeding programs in the near future.

Genetic parameters and diversity studies of yield and yield contributing characters in Brassica genotypes. Journal of Bangladesh Agricultural University, 17(3): 295-300. https://doi.org/10.3329/jbau.v17i3.43200 ABSTRACT The potential of a crop to favorably respond to breeding programs depends on its existing nature and magnitude of genetic variability, heritability and genetic advance. An experiment was conducted with eighteen Brassica genotypes following Randomized complete block design (RCBD) with three replications at the field of the department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh, Bangladesh to estimate genetic divergence, variability ranges and contribution of each trait towards genetic diversity. Analysis of variance showed significant variation among the genotypes for all the studied yield and yield contributing characters. The phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) for all the characters measured, indicated that the traits were influenced by environment. All traits showed high heritability (61.54% to 98.64%) which indicated possible improvement through selection. High heritability values (>60%) along with high genetic advance and genetic advance in percentage of mean indicated prevalence of additive gene action, which provides good scope for further improvement by selection. The genotypes were grouped into four clusters, most of the genotypes were grouped into Custer I (8 genotypes), while cluster IV contained only one genotype. Considering the mean value, the cluster IV and Cluster II were ranked as the top groups in terms of yield and early maturity. High Heritability with high genetic advance in percentage of mean was observed for number of branches/plant, number of pod/plant, number of seeds/pod and yield/plant and selection focused on these traits could be useful for future breeding program of Brassica. The genotype BD-7114 was the best performer considering all the studied traits especially yield and days to maturity which could be used as an important breeding material for the improvement of Brassica.

The experiment was conducted following RCBD with three replications. Thirty-one NERICA rice genotypes (twenty-eight mutant lines along with three parents) of advanced generations were used. Data were collected on twelve morphological traits. The results of the principal component analysis showed that the first four components account for 80% of total variation giving a clear idea of the structure underlying the variables analyzed. This result was also supported by scree test. Cluster analysis using Ward's method classified the thirty-one genotypes into five distinct groups. The maximum inter-cluster distance was observed between clusters indicating the possibility of high heterosis if individuals from these clusters are cross-bred. The results of PCA were closely in line with those of the cluster analysis. These results can now be used by breeders to develop drought tolerant high yielding rice varieties and new breeding protocols for rice improvement.

The experiment comprised 3 factors; Transplanting method, Variety and Gypsum. This variety was evaluated under two transplanting methods i.e., Furrow transplanting (T 1) and Conventional transplanting (T 2) and four levels of gypsum with control G0: control, G 1 : 50 kg ha-1 ,G 2 : 100 kg ha-1 and G 3 : 150 kg ha-1 .The experiment was laid out in a Latin Square Design (LSD) with three replications. Salinity level had significant negative effect on plant characters and yield of rice. Gypsum (@ 150 kg/ha) exerted positive significant effect on most of the plant parameters except number of non-Original Research Article Alim et al.; IJPSS, 29(4): 1-9, 2019; Article no.IJPSS.50809 2 effective tillers. Furrow transplanting method (T 1) had positive significant effect on most of the plant parameters except panicle length and harvest index. Binadhan-10 shows better performance than BRRI dhan28 in case of yield and all yield contributing characters in the prevailing condition. The highest grain yield (6.63 t h a-1) f o u n d f r o m T 1 V 2 G 3 (combination of furrow transplanting method, Binadhan-10 and gypsum @ 150 kg/ha) and lowest (4.26 t h a-1) i n T 2 V 1 G 0 (combination of conventional transplanting method, BRRI dhan28 and gypsum @ 0 kg ha-1). It was calculated that the straw yield highest (8.14 t ha-1) in T 1 V 2 G 2 (combination of furrow transplanting method, Binadhan-10 and gypsum @ 100 kg/ha) and lowest (5.61 t ha-1) in T 2 V 1 G 0 (combination of conventional transplanting method, BRRI dhan28 and gypsum @ 0 kg/ha).

estimate association for yield and yield contributing traits. The experimented was executed following Randomized
complete block design (RCBD) with three replications in the experimental farm of the department of Genetics and
Plant Breeding, Bangladesh Agricultural University Mymensingh-2202. The nine yield attributing characters are
studied in the experiment. The genotypes differed significantly for all the traits viz., days to 1st flowering, days to
maturity, plant height, number of branches/plant, number of pod/plant, length of pod, number of seeds/pod, 1000-
seed weight (g) and seed yield/plant (g).Considering the two most important traits like early maturity and yield
/plant, BD-7114 performed best among the studied genotypes. Correlation coefficients among the characters were
studied to determine the association between yield and it attributing components. A significant positive correlation
was found between yield and its attributing characters namely with number of seeds/pod and 1000-seed weight. Path
analysis revealed both direct and indirect effects on seed yield and revealed that number of seeds/pod had the
highest direct effect on seed yield. The findings of the research could be exploited in future breeding programs for
improving Brassica genotypes.

Twenty-six arthropod species were observed through visual searching method out of which 18 were insect pest species (from 14 families under 8 orders) and 8 were natural enemies (from 8 families under 6 families). Twenty one species of surface dwelling arthropods were caught in pitfall traps method, 12 of them were insect pest species (from 11 families under 8 orders) and 9 were natural enemies (from 9 families under 5 orders). Formicidae was the most abundant family among them. Bacillus thuringiensis (Bt) and Tracer 45SC (Spinosad) were less harmful to arthropod pest species as well as natural enemies in the brinjal agro-ecosystem. Proclaim 5SG reduced the overall abundance of arthropod species. Bacillus thuringiensis (Bt) and Tracer 45SC were relatively safe for natural enemies and therefore would be fit well into integrated pest management (IPM) against BSFB of brinjal crop.

Five (5) advanced inbreds of pumpkin viz IB 23, IB 40, IB 47, IB 50 and IB 57 were used in this study. The five parents and their F 1 hybrids were arranged in a randomized complete block design with three replications for studying the quality and yield contributing traits. Analysis of variance showed significant differences among genotypes for all of the traits except dry matter and fruit yield. Parental mean suggested that all the parents contained recessive alleles with positive effect. In the 5 × 5 diallel set, Wr-Vr graph analysis revealed the presence of allelic interaction in all the character's except fruit length, dry matter, brix percentage and reducing sugar where non-allelic interaction was present.

Predominance of additive-additive gene action was noted for most of the characters except hollowness and dry matter content, where additive-dominance gene action was predominant; flesh thickness and brix percentage, where dominance-dominance gene action were predominant. Among all five parents, no parent was found as good combiner for more than two characters. The parent IB 23, IB 40 and IB 57 was found good general combiner for the trait dry matter content, fruit length and non-reducing sugar. The best specific combiners were IB 23 X IB 40 for fruit breadth, brix percentage, non-reducing sugar, total sugar and fruit yield; IB 40 X IB 50 for hollowness and beta carotene; IB 40 X IB 47 for flesh thickness; IB 40 X IB 57 for brix (%) and IB 23 X IB 57 for reducing sugar.
