Genetic variability, heritability and genetic advance in Lentil (Lens culinaris Medik.)
Journal of agriculture and natural resources, 2022
The present study was carried out to study the variation, broad-sense heritability, and genetic advance, correlation among traits for growth, yield, and its attributing traits in lentil genotypes. Sixty lentil genotypes were evaluated in augmented design in 2020 at Khajura, Banke. The results indicated that the genotypes were significantly different for days to flowering, days to maturity, 500 seed weight and grain yield kg/ha. The phenotypic coefficient of variation (PCV) was greater than the genotypic coefficient of variance (GCV) for all traits. The 500 seed weight showed the highest PCV (22%) and GCV (21%) whereas days to maturity showed the lowest PCV (5.5%) and GCV (3.2%). The highest value (90%) of heritability (broad sense) was in and lowest (3%) in pods per plant. Genetic Advance Mean 40% was the highest for seed weight but lowest at 1.2% in pods per plant. Grain yield showed a positive and significant correlation in genotypic level with days to maturity (r = 0.7**), plant height (r = 1.66*), pods per plant (r = 1.15**) and seed weight (r = 0.56*). Path analysis found that the seed weight had the most impact on grain yield followed by pod per plant. Thus, selection for yield in lentils through these characteristics would be effective in the varietal developmental program.

Aims: To evaluate the genotypes for different yields and yield attributing morphological traits by estimation of GCV, PCV, heritability (h2) in a broad sense and genetic advance as percent of the mean. To study the character association between yield and yield attributes and further partitioning into their direct and indirect effect on yield for consideration of appropriate traits to facilitate the selection of desirable genotypes. Place and duration of Study: Lentil genotypes were evaluated in the instructional farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal during the rabi season of 2019-2020 and 2020-2021. Methodology: Forty lentil genotypes including two checks viz., WBL77 and IPL220 were evaluated in alpha lattice design with three replications following the standard cultural practices. The observations were recorded as the average of the same in five randomly sampled plants in each plot for all the eleven attributes studied. Statistical analysis ...

Enormous genetic variability was created as expressed in terms of range, mean and the coefficient of variations in all F<sub>2</sub> populations studied. The crosses viz., L-830 × P-1117, JL-3 × P-22211 and SKL-259 × P-22211 produced higher percentage of transgressive segregants with desirable traits. Days to 50% flowering and days to maturity manifested high heritability, coupled with low genotypic coefficients of variation (GCV) and genetic gain, indicating requirement of selections for several successive generations for their improvement. Low to medium heritability accompanied by high coefficients of variation and genetic advance for seed yield indicates complexity of the character improvement through simple selection. High heritability accompanied by moderate to high GCV and genetic gain were observed for other yield components studied, which could be improved by simple selection in early generations. Thus, the study exhibited the possibilities of improving lentil ge...

The present investigation was carried out on thirty-six lentil genotypes at the farm of Bihar Agricultural University, Sabour, Bhagalpur in 2018-19. The genetic divergences were examined using Mahalanobis D2 statistics for two dates of sowing i.e normal sown and late sown condition. The presence of variation among genotypes was revealed by ANOVA for considerable traits which come out as significant for all traits under study except several primary branches per plant, the number of pods per cluster under both normal and late sown condition and the number of seeds per pod in late sown condition. The study on genotypic variability, correlation and path analysis was done to know the direct and indirect relationship on seed yield and yield components for enhancement of economic yield. The total genotypes were grouped into 7 clusters under a timely sown condition such as. Cluster I being the largest comprising 10 genotypes, followed by cluster II with 8 genotypes, cluster III with 7 genot...

Understanding phenotypic and genotypic variability of Bangladeshi lentil (Lens culinaris Medik.) in relation to exotic lentil is important in attempting to widen the genetic base of the germplasm in the country. An experiment was conducted using 30 diverse lentil genotypes to study the agromorphological and genetic variability, heritability, expected genetic advance and inter-relationship of ten yield attributing traits. The genotypes showed highly significant (p<0.01) variations for all of the studied traits. These characters also had higher phenotypic co-efficient of variation (PCV) than those of the corresponding genotypic co-efficient of variation (GCV). High heritability (ranged from 66-98%) was found among the traits. Seed yield plant-1 and number of seeds plant-1 showed high heritability accompanied with high genetic advance (as percent mean). Correlation coefficient studies revealed that number of pods plant-1, number of seeds plant-1 and 100-seed weight contributed to hi...

The present study was undertaken at DARS, Budgam to study the variability and diversity in exotic accessions of lentil. A set of 45 genotypes of Lentil comprising 44 accessions from ICARDA BIGM nursery and a local variety Shalimar Masur 1 as check were evaluated for various agro-morphological and quality traits. Significant variability was found for all the traits under study. Large differences between phenotypic and genotypic variances were found for these two traits, which means environment has a role in these traits. Plant height was correlated with days to maturity and flowering, which means late flowering due to temperate conditions, can affect plant height. Primary branches per plant, pods per plant and seeds per pod were positively and significantly correlated with seed yield per plant. The said set of 45 genotypes was divided into 7 clusters, the check was found in cluster IV. Considerable inter and intra cluster distances were found. In cluster VI two genotypes were placed which were bold seeded but exhibited higher yield than the check. The above set was also morphologically characterized for stem, flower and seed traits as per PPV&FR guidelines. Considerable variability was found for seed characters also.
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.
The present study was conducted to assess the genetic variability parameters and associations among the yield, yield attributing and nutritional traits. Variation analysis revealed a narrow difference between PCV and GCV estimates for most of the characters except seed/pod, biological weight and seed yield per. All traits show high heritability coupled with high genetic advance for most of the traits suggesting the preponderance of additive gene action. Correlation coefficient study revealed that seed yield/plant shows significant & positive relationship with biological weight, pods/plant, harvest index, hundred seed weight & seed/pod. The result of association analysis revealed that biological yield per plant and harvest index were the most important components for getting higher yield. The lentil genotypes were also characterized for stem, flower, leaf, growth habit and seed traits as per PPV&FRA guidelines showing considerable variability for all characters studied.
Genetic Variability and Heritability Estimates of Agronomic Traits in Lentil (Lens culinaris Medik.)

Assessing genetic variability and heritability of the targeted traits is among the crucial first steps toward lentil crop breeding. With the aim of estimating genetic variability and heritability of the crop traits and screening the most promising genotypes, a total of 12 lentil genotypes (11 lines from ICARDA, Syria, and one local cultivar) were evaluated at three locations of the Sulaimani region, northern Iraq during 2018-2019 season. Results showed a significant (P≤0.05) genetic variation among the lentils for most of the agro-morphological traits. In pairwise comparisons, ICARDA lines Flip 93-36L and Flip 2009-70L showed the best performance for most of the evaluated traits and were identified as the most promising for local cultivation and breeding goals. The very significant positive and negative correlations were between seed yield with biomass (r=0.89) and number of days to emergence (r=-0.89). The highest to lowest broad-sense heritability (H2 ) values were recorded for 10...

A panel of fifty diverse genotypes of lentil were evaluated to assess the genetic diversity for 11 morpho-physiological attributes. The results revealed wide range of variability among the genotypes for the examined characteristics. The mean performance demonstrated that the best genotype for more than one trait viz., plot yield, yield/plant, Leaf Area Index (LAI), Crop Growth Rate (CGR), biomass and plant height was LL1384. Traits association approximation witnessed a positive and significant relationship of seed yield with most of the studied traits. Cluster analysis distributed genotypes into seven distinct clusters. Cluster III happened to be the largest comprising of 20 genotypes, followed by Cluster VII comprising of 9 genotypes. The maximum inter-cluster distance was perceived between clusters II and IV which suggests the possibility of high heterotic effect if cross will be made between the individuals of these clusters. The principal component analysis developed 11 Eigen ve...
