Abstract

Cold stress during early stage of crop growth badly affects the survival of plants and drastically reduces the seed yield. Therefore, a set of 230 genotypes of mungbean were assessed for genetic variability, heritability, genetic advance for yield and related ancillary traits over two locations in winter season. The test germplasm lines revealed significant variability for all the traits. The estimates of PCV were higher than GCV for all characters under study and the deviation was comparatively more in case of single plant seed yield suggesting greater influence of G × E interaction. The broad sense heritability estimates were found higher in number of days to 50% flowering, plant height, 100-seed weight, pod length and seeds per pod. Higher estimates of heritability along with extremely high genetic advance was observed for number of clusters per plant indicating major role of additive gene action. Such component trait-specific selection would be rewarding for enhancement of yield p

Conclusion

The present findings would be helpful for formulation of selection strategy for identification of parent materials in a set of germplasm lines as well as selection of elite plant types in mungbean breeding programme under cold stress.
