Analysis of genetic variability parameters for pod-shattering and yield related traits in F2 and F2:3 populations of mungbean [Vigna radiata (L.) Wilczek]

Abstract


Mungbean is an important pulse crop with multiple benefits such ashigh protein content, short duration, soil restoring capacity and canbe used as catch crop and livestock feed. One of the main reasons forits low productivity is shattering of the pods before or during theharvesting of the crop in the field. Little efforts have been made tostudy this trait especially in mungbean. In the present study, twogenerations [(F2 2015-16), (F2:3 and F2 2016-17)] derived from thecross Chinamung × Pantmung-2 were studied for pod shattering andyield related traits. Screening of two segregating generations at theMain Agricultural Research Station, Dharwad during summer 2015-16 and 2016-17 indicated significant positive correlation betweenpod shattering and number of twists per pod and between yieldrelated traits. The high heritability coupled with high genetic advanceas per cent mean was observed for pod shattering percentage in bothF2 (2015-16) and F2 (2016-17). Hence, this trait should be taken intoaccount while selecting superior and desirable plants for furtherimprovement of yield parameters and pod shattering resistance inmungbean.
