LEGUME RESEARCH - AN INTERNATIONAL JOURNAL, 2017
Character association in forty eight genotypes of lentil was studied for nine different agro-morphological characters in normal and late sown conditions. Normal sown condition was taken into consideration as optimum environment and late sown as heat stressed environment. The correlation study revealed consistent positive significant character association (at genotypic and phenotypic levels) of pods per plant with seed yield per plant in both sowing conditions. So this character may be considered for yield improvement. From path coefficient analysis study it was revealed that pods per plant showed consistently positive direct effect on seed yield/plant for both sowing conditions.

Harvest yield relies on the quality of seed sown. To get the best returns, the quality of the seed should be of top priority. Seed physical, biochemical characters contribute to the success of seed. If the crop is taken in fallow conditions, the ultimate success of the crop depends on seed characters and quality. The present investigation was undertaken to characterize the relationship between the seed characters and quality of lentil WBL-58, at the department of plant physiology, B.C.K.V during the year 2017-18. Concerning physiological standpoint, seed screening is most important to mitigate the stress for late sown lentil in West Bengal field condition and to develop an effective protocol to grow a healthy crop with better yield.
Evaluation of seed characteristics in three lentil (Lens culinaris Medik) genotypes
Scientia Agriculturae, 2016
The purpose of this study was to investigate some physical traits of three lentil genotypes. The present study was done based on a randomized complete block design with five replications. For this work some physical traits including 100 seed weight, seed volume, bulk density, true density, grain turgidity, turgidity index, water absorption capacity, water absorption index and grain porosity were examined in the laboratory in 2011. The results showed that 100 seed weight and bulk density had the highest (32.2%) and lowest (5.15%) coefficient of variation respectively. All traits except seed true density had the significant difference. Qazvin cultivar with higher 100 seed weight 3.89 g, seed volume 25.2 μl/seed, turgidity 25.4 μl/seed, water absorption capacity 28.2 mg/seed, water absorption index 1.01 and porosity 47.8% had a significant difference with two other genotypes. 100 seed weight had positive and negative significant correlation with seed volume, turgidity, water absorption capacity traits and water absorption capacity index, respectively. Turgidity index trait had no significant correlation with any of the traits. The results showed that in general, selection of 100 seed weight, seed volume and seed turgidity in macrosperma and the bulk density of microsperma lentils can help to improve these traits.

Genetic variability in lentil (Lens culinaris M.) genotypes for seed and seedling characteristics
Journal of Pharmacognosy and Phytochemistry, 2019
In this study, thirty genotypes of lentil (Lens culinaris M.) were evaluated in randomized block design with three replications during 2017-18 in laboratory of Department of Plant Breeding and Genetics, SKN college of agriculture, Jobner to determine genetic variability, heritability and genetic advance for seed and seedling characteristics. Observations were recorded on 100 seed weight, seed volume, true density, bulk density, porosity, water absorption capacity, water absorption index germination, seedling length, seedling fresh weight, seedling dry weight and seedling vigour index. The analysis of variance indicated significant difference among genotypes and considerable variability with respect to all the characters except germination percentage. The highest PCV and GCV expressed as percentage was observed for porosity followed by seed volume, seedling length and seedling vigour index, whereas low for bulk density and water absorption index. The estimates of heritability were high for all the characters ranging from 61.39 to 97.37. The estimate of very high heritability with high genetic advance was observed for seed weight, seed volume, water absorption capacity and seedling dry weight whereas high heritability with low genetic advance was recorded for bulk density.
Stability Analysis for Seed Yield in Lentils (Lens Culinaris MEDIK.)
2011
The development of genotypes, which can be adapted to a wide range of diversified environment, is the ultimate goal of plant breeders in a crop improvement program. In this study, linear regression were used to analyze the response to environmental conditions of lentil (Lens culinaris Medik) genotypes taking as independent variable (X) the average yield of all lentil genotypes in four experiences (two locations and two years). Yield stability was assessed by determining the coefficients of variation. Seven lentil genotypes were tested for seed yield in two locations of Southern Romania environmental conditions during 2008 and 2009 growing seasons. On the basis of the regression coefficient g enotypes Idlib-1, Idlib-2, Idlib-3, Hurani and Kurdi had general adaptability to over environments and genotypes Idlib-4 and Oana were suitable for favorable environments. The result of coefficient of variation indicated that the same genotypes were more stable. Among these Idlib-3 genotype was ...

Landraces are a valuable source of genetic variability for breeders to develop high-yielding lentil varieties. Apart from productivity, simultaneous breeding for lentil seed nutritional quality is of paramount importance for wider lentil consumption. This work examined the indirect effect of single plant selection for high yield on important seed quality traits within three Greek lentil landraces (“Elassona” (EL), “Lefkada” (L), and “Evros” (EV)). The breeding methodology applied was proved to help either maintain or improve such characteristics in the high-yielding second-cycle lines (SLs) selected. Compared to the parental landrace “Elassona”, the high-yielding lines showed increased crude fiber by 30–110%; the line 2-SL-EL-6 had higher starch content by 3.9% and reduced cooking time by 6.67 min, while the 2-SL-EL-10 line had higher crude fiber by 73%. In the case of “Lefkada”, the high-yielding lines selected maintained the protein content present in the parental landrace, apart ...
Background: Lentil is the major cultivated pulse crop in the state of West Bengal in terms of total area coverage under cultivation. Selection of high yielding and better quality genotype is the prime vital matter to increase productivity. Investigation and a better understanding of the variability existing in a population base of the crop are pivotal to crop improvement so that the plant breeders can exploit it. Methods: The current study has been carried out at the experimental farm of the University of Calcutta during 2016-2017 in a plot designed with the randomized block design. It was carried out to estimate the magnitude of genetic variability, heritability and genetic advance of fifty-four lentil germplasms. Result: Moderate to high heritability, GCV, PCV, GA and GA % of mean was obtained by days to1 st flowering, days to 50% flowering, pods per plant and harvest index. The genotypic and phenotypic association of seed yield was significantly positive with traits like plant height, pods/plant, 100 seed weight and harvest index. Characters like days to 50% flowering, plant height, primary branches per plant, pods/plant, pod length, 100 seed weight and harvest index shows a positive direct effect on seed yield in path analysis suggesting select for such traits while exercising selection for seed yield per plant in lentil.
A study on genetic diversity in lentil genotypes using seeds morphologic and protein traits
Life Science Journal, 2012
The following research tries to study the relation and correlation between grain yield and other quantitative traits in lentil using 29 lentil genotypes (including 26 foreign genotypes and 3 control genotypes). The research was conducted in Ardabil Agriculture and Natural Resources Research through augmented method in randomized complete block design in three replications, during 2011. During the agricultural season, certain traits such as green percentage, days to flowering, number of hooks, hook size and grain yield were measured. Subsequent to the variance analysis, data related to the control cultivars, and also estimation of blocks effects and amending each studied treatment on the studied traits, the relation between evaluated traits and grain yield were studied. Results suggested that there is a positive significance relation between the green percentage, hook size, plant height, 100 pods weight, 100 seeds weight, biomass and number of filled pods on the one hand and the grain yield on the other. Step-by-step multiple Regression results indicated that among the studied traits, biomass and number of secondary branches explain more than 84% of the grain yield changes so that, the increase in biomass and decrease in number of secondary branches, increase the yield. Cluster analysis divided studied genotypes into three groups in which, the first group with genotype numbers of 1, 5, 6, 9, 10, 11, 14, 15 and 21 was the best group. According to the protein data, the highest number of protein band (22) were observed in genotype numbers of 8, 21 and control genotype number of 27 while the lowest number of protein band (16) were observed in genotype numbers of 19 and 20, so that bands numbers of 2, 3, 5, 7, 8, 13, 14, 15 and 16 with respective molecule weight of 118.35, 112.71, 99.77, 86.17, 80.09, 44.58, 42.46, 40.43 and 38.51 KD a were diagnosed as polymorphism bands. According to the protein data, genotypes were divided into three groups in which the third group with 12 genotypes of 1, 2, 3, 4, 5, 6, 11, 12, 13, 15, 20 and 22 had a higher value as the delayed, high yielding and long-legged genotypes along with most of studied traits. The farthest distances from protein bands were related to the genotypes numbers of 23 with 14, 17, 18 and 19. Results suggested that grouping based on morphologic data was to 35% consistent with protein data.
Genotype x environment interaction and stability analysis for yield and its components in lentil
Genotype x environment interaction and stability analysis for yield and its components in lentil, 2013
"The objective of this investigation is to determine the performance and stability of 24 lentil (Lens culinaris Medik.) genotypes under a wide range of variable environments. The regression model and ecovalence (Wi) were used to analyze the response of the lentil genotypes to variable environmental conditions for yield and some of its components in six experiments in three seasons under two locations. Results indicated that both environmental conditions (E) and studied genotypic accessions (G) influenced significantly on the performance of yield and yield components. Moreover, the performance of genotypes varied highly significantly from environment to another for all traits, except 100 seed weight as proved by significance of G x E. Therefore, further stability analyses were performed for traits that recorded significant G x E. Four genotypes were stable for pods plant-1 either measured by Wi or S2 d. For this trait, all genotypes were non responsive to environmental conditions except PL81-17 which may behave positively to pod bearing conditions. For seed yield plant-1 only Sinai 1 was significantly unstable measured by Wi and S2 d, respectively. The significance of b's for seed yield feddan-1 proved that only 3 genotypes were responsive to environments. Two of them (XG88-17 and Giza 51) may behave better under good environments and the third (Giza 4) may be recommended under poor ones. It may be concluded in lentil breeding programs, which the performance of genotypes under each location should be evaluated firstly and those reliable ones will be tested for stability across various environmental conditions prior to recommendations."
