Background: Lentil is one of the most significant pulse crops, frequently referred to as "poor man's meat" because of its high protein content and inexpensive price. The present study was assessed for eleven morphological and yield variables to determine genetic variability, correlation and path co-efficients. Methods: The experiment was conducted in a randomized complete block design using 56 different homogeneous progenies of a spontaneous mutant of lentil variety DPL 62 and four control varieties in triple replica during rabi 2017-18. Result: Significant amount of variability was observed for all the traits. High phenotypic coefficients of variance and genotypic coefficients of variance coupled with high heritability and genetic advance were observed for peduncle length, number of pods per plant, seed width, seed yield per plant suggesting that these traits are genetically controlled by additive gene action. Seed yield per plant exhibited significant positive association with number of branches/plant and number of pods/plant while number of pods/plant revealed highest positive direct effect on seed yield per plant followed by 100-seed weight, number of branches per plant, days to maturity and leaflet breadth. Therefore, selection for these characters will directly lead to improvement in the yielding ability of lentil genotypes. [ABSTRACT FROM AUTHOR]

The present study was focused on evaluating the F3 population of VBN 11 x LBG 17 based on 10 yield components and the per cent disease index (PDI) for powdery mildew. Variability, correlation, and path analyses were performed to examine the data. The F3 population exhibited a wide range of variation for both yield components and PDI. Notably, the number of branches per plant, PDI, and seed yield per plant (g) showed high phenotypic and genotypic coefficients of variation. Furthermore, PDI alone displayed high heritability along with a high genetic advance as a percentage of mean. Moderate heritability and high genetic advance as a percentage of mean were observed for plant height (cm), number of branches per plant, total number of pods per plant, and seed yield per plant (g). These findings suggest that these traits are influenced by additive gene action and are suitable for effective selection. Correlation analysis revealed that all traits, except PDI and 100-seed weight, were significantly associated with seed yield per plant (g). Path analysis indicated that the total number of pods per plant had a substantial direct effect. Consequently, the total number of pods per plant can serve as a selection index for yield improvement programs. Notably, PDI exhibited no association with seed yield per plant (g), suggesting that resistant genotypes can be developed without any adverse correlation among yield components.

Fifty two genotypes of Indian bean were examined for the genetic variability parameters and trait correlation for 11 yield contributing traits in F5 progenies. Analysis revealed that these genotypes had a considerable level of diversity. The magnitude of GCV and PCV was high for seed yield per plant, which indicated the potential for selection based genetic enhancement. The GCV and PCV values were moderate for pod weight, pods width and pod length. High heritability along with high genetic advance as per cent mean was recorded for pod width, pod length, pod weight and seed yield per plant. The seed yield per plant had a significant positive correlation with pod weight, plant height, pod length, pod width and seeds per pod. The overall genotypic path analysis revealed that racemes per plant exhibited the highest positive direct effects on seed yield per plant followed by direct effects of pod length, pods per raceme, pod width and pod weight. Therefore, simple selection is advised for pod length, pod width and pod weight to boost the yield of the Indian bean. Based on mean values, the progenies W-19-26, W-19-22 and W-19-25 of GNIB-21 × GP-167 among all crosses had shown significantly higher seed yield over the check varieties GNIB-21 and GNIB-22 and hence identified as elite genotypes.

A field experiment was undertaken to evaluate the variability and performance of thirty horsegram genotypes collected from various regions of Kerala and outside for yield and yield attributing characters. Analysis of variance was carried out based on the recorded observations, and it showed significant differences among the 30 genotypes for all the fifteen characters studied. Most of the traits exhibited narrow differences between PCV and GCV except for seeds per pod, the number of primary branches per plant and yield per plant. Yield per plant was found to be significant and positively correlated to primary and the number of secondary branches per plant, nodes per plant, pod number per plant, seeds per pod and 100 seed weight both at phenotypic and genotypic levels. Path analysis revealed that pod number per plant, seeds per pod, nodes per plant, 100 seed weight and days to maturity were the major yield contributing characters owing to their favorable direct effect on yield per plant. Genetic diversity studies using Mahalanobis' D² statistics assembled the 30 genotypes into eight clusters. [ABSTRACT FROM AUTHOR]

The experiment was carried out to determine the genetic variability parameters and character associations for eleven quantitative traits in Indian bean genotypes. It revealed a significant amount of variability present among these genotypes. Seed yield per plant had high Genotypic coefficient of variation (GCV) and Phenotypic coefficient of variation (PCV) values, showing the potential for improvement by selection. Racemes per plant, pods per raceme, pods per plant, and pod weight had moderate GCV and PCV values. There was high heritability combined with a high genetic advance for pod weight and seed yield per plant. Plant height, pods per plant, and pod weight were significantly and positively associated with seed yield per plant. Pods per plant had the most positive direct effect on seed yield per plant, followed by racemes per plant, plant height, pod weight, pod length, and seeds per pod. Therefore, selection for such traits is advised to bring about improvement in Indian beans. [ABSTRACT FROM AUTHOR]

In a study carried out with 71 genotypes of Indian mustard under sub-Himalayan condition during rabi 2017-18, it was found that all the genotypes differed significantly for yield and its attributing traits. Both GCV and PCV were found to be higher for height up to first fruiting branch, aphid count and penetration force indicating high variability in the genotypes. High heritability along with high genetic advance was observed for height up to first fruiting branch, primary branches per plant, secondary branches per plant, siliquae per plant and 1000 seed weight. The trait association study revealed that secondary branches per plant and siliquae per plant had positive significant association with seed yield per plant. Path coefficient analysis indicated that penetration force exhibited the highest direct effect on seed yield. Siliquae per plant and secondary branches per plant exhibited high direct positive effect and positive association with seed yield per plant. On the basis of all the eleven traits taken together, the genotype PRD-2013-9 (rank-1) was the best. [ABSTRACT FROM AUTHOR]
