EFFECTIVE SELECTION CRITERIA FOR YIELD IMPROVEMENT IN INTERSPECIFIC DERIVATIVES OF MUNGBEAN [Vigna radiata (L.) Wilczek]

Balraj Singh, Dr. T. S Bains

Abstract :

Mungbean [Vigna radiata (L.) Wilczek] also known as green gram or moong, one of the most important pulse crop is extensively grown in South and South East Asian countries. The average productivity of mungbean is very low in comparison to cereals. Grain yield is a complex character hence selection based on yield is not effective. Hence selection based on traits other than yield can be more effective. Interspecific hyidization is important for genetic enhancement of crop plants. The present study is therefore conducted with the objective to identify the component traits for selection for yield improvement involving derivatives of interspecific crosses. A set of 58 interspecific derivatives of mungbean and 6 checks were grown in a simple lattice design in summer and kharif seasons to determine association among different traits and their contribution towards seed yield. It was found that in both summer and kharif seasons, plant height, 100 seed weight, days to 50% flowering, days to maturity and harvest index are most important parameters for selection for higher yield whereas number of pods per plant and biological yield are important only in the kharif season in interspecific derivatives of mungbean.
