“…Yield per plant also showed significant to highly significant positive correlation with plant height (0.453**), number of clusters per plant (0.331**), number of pods per cluster (0.478**), number of pods per plant (0.468**), pod length (0.297*), pod weight (0.463**), and seeds per pod (0.517**). These results are in close conformity with the finding of Rasel Miah et al, (2016) [7,9] , C R. Konda et al, (2018) [12] , Sridhar et al, (2019) [17] , Shalini et al, (2019) [19] and Bhanu Pratap et al, (2019) [18] . Negative significant association exhibited by pod length (-0.225* ) with the yield per plot.…”

“…The narrow difference between PCV and GCV indicated the less influence of the environment on these characters. The results are similar with Singhal et al, [8] [17] for plant height in black gram, Kumar et al, [18] for number of branches, number of pods per plant, Seed yield per plant and plant height in black gram, Mate et al, [19] for number of pods per plant and Nimbal et al, [20] for seed yield per plant in horse gram, Verma et al, [21] for plant height, number of branches per plant, number of pods per plant, pod weight and 100 seed weight in cowpea. Moderate estimates of heritability and genetic advance was observed for number of seeds per pod.…”

The present investigation was carried out with 78 diverse horse gram [Macrotyloma uniflorum (L.) Verdc] genotypes along with 4 checks during the late Kharif season. Data was recorded on days to 50 percent flowering, days to maturity, plant height, number of branches per plant, pod length, number of seeds per pod, number of pods per plant, pod weight (g), seed yield per plant (g), and 100-seed weight (g). Analysis of variance revealed significant differences among all the genotypes for all the characters studied. A wide range of variations had been observed for all the characters except for the number of seeds per pod. The highest coefficient of variation was observed in the number of pods per plant followed by 100 seed weight and seed yield per plant. The phenotypic coefficients of variation (PCV) were higher than the genotypic coefficient of variation (GCV) for all the traits but the differences were narrow. The highest magnitude of PCV and GCV were recorded for seed yield per plant (g) followed by pod weight (g) indicating a wide range of variation which provides a chance for yield improvement. High heritability coupled with high genetic advance was observed for plant height, number of branches per plant, number of pods per plant, pod weight, seed yield per plant, and 100 seed weight indicating additive gene action and the abundant scope for improvement in these traits through simple selection. This study provides information about the performance of the genotypes and identifies some prominent genotypes. Thirty-three genotypes recorded significantly higher seed yield per plant as compared to the best-performing check. These genotypes were IC 426292, IC 470167, IC 426471, IC 470229, IC 470206, IC 470262, IC 426464, IC 107247, IC 108076, IC 426550, IC 426540, IC 108078, IC 426537, IC 470166, IC 467865, CRHG-1, IC 426539, IC 426478, IC 426524, IC 426549, IC 426522, IC 470170, IC 261278, IC 470188, IC 426535, IC 107222, IC 226533, IC 426574, IC 426523, IC 526965, IC 426571, IC 426517 and IC 426538. These genotypes may be further used for parental selection in breeding programs for the improvement of yield and its attributes in horse gram.

“…The lowest difference is exhibited by hundred seed weight indicating the highest contribution of genotypic value to the phenotype and low influence of environmental factors suggesting for a genetic gain for this trait through selection. The moderate PCV for the number of branches per plant, hundred seed weight and plant height was observed byPanda et al (2017); the number of pods per cluster, pod length and the number of pods per plant was observed byVikky et al (2020) in blackgram.…”

One hundred and eighty nine stabilised lines obtained from the cross VBN (Bg) 5 and Vigna mungo var silvestris 22/10 were evaluated during Rabi, 2019. Analysis of variance for various traits exhibited significant differences among the lines for all the nine quantitative traits. The GCV was lower compared to the values of PCV which revealed the influence of the environment in deciding the expression of these lines. Moderate GCV was recorded for single plant yield (16.22 %), the number of pods per plant (12.60%), plant height (12.48 %), the number of primary branches per plant (11.75 %) and hundred seed weight (11.34%). High heritability was observed for the characters like hundred seed weight (96.99 %), plant height (78.33 %), days to 50 per cent flowering (72.98 %), single plant yield (72.44 %) and pod length (65.70 %). High heritability along with high genetic advance as per cent of mean was observed for hundred seed weight (96.99, 23.00), plant height (78.33, 22.76) and single plant yield (72.44, 28.44) indicates the possibility of improving these traits by selection since there is a wide range of variation and additive gene action exists for these traits. The maximum number of lines with a positive value over the mean was observed for pod length and 100 seed weight. Correlation analysis showed that the number of pods per plant, plant height, the number of seeds per pod, the number of primary branches per plant, the number of pods per cluster, pod length and hundred seed weight had positive significant association with single plant yield. A number of pods per plant and pod length had a high positive direct effect on single plant yield. Hence, the selection for these characters would improve seed yield in blackgram.
