“…The direct selection of these characters may improve yield. Similar results were produced by Mishra et al [13], Vadivel et al [14] Sineka et al [15] and Salman et al [16] in mung bean. High heritability with moderate genetic advance as percent mean was shown by characters days to 50 % flowering, pod length and number of seeds per pod.…”

Mung bean (Vigna radiata L. Wilczek) is one of the most important pulse crops due to the high content of protein as well as the ability to nitrogen fixation in soil. Seed yield is the most complex trait which highly influenced by other traits and also the environment. In this view, the study was aimed to evaluate the relationship between yield and yield attributing traits of sixty genotypes of Mung bean. The genotypes exhibited significant variability in respect to all the fourteen quantitative characters studied. Genetic variability studies showed presence of good amount of variation among the sixty genotypes. Highest PCV and GCV was recorded by seed yield followed by number of seeds per plant and primary branch length. The characters, seed yield per plant, number of seeds per plant, primary branch length, biological yield, harvest index, 100 seed weight, number of pods per plant, number of clusters per plant, plant height and number of primary branches had shown high heritability coupled with high genetic advance as percent mean. Seed yield per plant had shown highly significant and positive correlation with number of clusters per plant, number of pods per plant, pod length, number of seeds per pod, number of seeds per plant, biological yield and harvest index at both phenotypic and genotypic levels. Path analysis showed that biological yield and harvest index were the most important characters for yield improvement.

“…Single plant yield exhibited maximum heritability followed by plant height, hundred seed weight and the number of clusters per plant. This result is in corroboration with Mishra et al (2008), Vadivel et al (2020) and Salman et al (2021) in greengram. The number of pods per cluster exhibited low heritability.…”

Greengram (Vigna radiata (L.) Wilczek) is one of the highly consumed legumes and has the ability to withstand wide environmental conditions. Sixty greengram genotypes were evaluated for genetic relatedness with 11 quantitative traits viz., days to 50 per cent flowering, days to maturity, plant height, the number of primary branches per plant, the number of clusters per plant, the number of pods per cluster, the number of pods per plant, the number of seeds per pod, pod length, hundred seed weight and single plant yield. The data were subjected to variability, genetic advance, heritability, correlation and path analysis. In this study, the phenotypic coefficient of variation and genotypic coefficient of variation was found to be high for the number of clusters per pod and the number of pods per plant. High heritability was noticed for single plant yield, plant height and hundred seed weight. The genetic advance was found to be very high for the number of pods per plant. Association studies revealed that the single plant yield was significantly correlated with the number of pods per plant (0.75) followed by the number of pods per cluster (0.60), the number of clusters per plant (0.58) and the number of seeds per pod (0.49). The direct and positive effect was recorded for the traits viz., days to maturity (1.44), the number of pods per cluster (0.67), pod length (0.46) and plant height (0.24). Phenotypic selection of traits contributing to grain yield exhibiting high heritability and genetic advance would help in the selection of superior genotypes for the improvement of grain yield in greengram.

“…Low genetic advance as per cent of mean was observed for days to 50 per cent flowering (7.74), pod length (6.68) and the number of seeds per pod (5.42) (Table 2). High genetic advance as the per cent of mean was reported by Asari et al (2019) and Salman et al (2021) for the number of pods per plant, single plant yield and number of clusters per plant.…”

Background: Greengram is third most important pulse crop which is widely adapted and can improve soil fertility. The genetic variability and association studies help in selection which would increase the yield potential of greengram. Methods: Two hundred stabilized lines (F9) obtained from the cross VBN (Gg) 2 and Vigna radiata var. sublobata were evaluated. The yield and yield contributing traits were recorded to evaluate genetic variability, heritability, genetic advance as % of mean and correlation among the yield and its component traits. Result: Analysis of variance exhibited significant differences among the lines for all the ten quantitative traits indicating the presence of genetic variability. The high GCV values were found for the traits viz., single plant yield (30.18) and the number of pods per plant (26.80). High heritability combined with high genetic advance as per cent of mean was observed for the number of pods per plant (90.19, 52.43), single plant yield (89.58, 58.84), the number of pods per cluster (79.28, 22.70) and the number of clusters per plant (69.50, 30.22) which indicates additive gene effects. In the present study, the number of pods per plant had a high positive direct effect (0.919) on a single plant yield. Therefore, the selection for these characters would improve yield in greengram.
