Abstract

The aim of this work was to study γ-radiation induced synchony in the maturity of mungbean and correlation of days to flowering and pod maturity between two diverse mungbean genotypes. The results showed reduced synchronous flowering with no correlation between flowering and maturity period. The mungbean genotypes 'K851' and 'Sona' had reduced flowering and late maturity in mutated lines with an exception of early maturity in 10 Gy in 'Sona'. Degree of indetermination (DDd) was controlled by both additive and dominant gene effects with predominance of additive component. Constant genotypic variance and high broad sense heritability for days to first flowering (D1), days to first pod maturity (D2) and DDd from first pod maturity to 90% pod maturity (DDd2) indicated an opportunity for successful selection of mungbean genotypes for uniform pods maturity. Selection of elite mutant lines with synchronous maturity (SM) would be possible in the M3-M4 generations.
