Enhancement of Genetic Variability for Yield and Component Traits through Recombination followed by Induced Mutagenesis in Greengram [Vigna radiata (L.) Wilczek]

摘要

Aim: Greengram is a self-pollinated crop which show very less variability to develop improved varieties through only hybridization or induced mutation breeding. Therefore, we have taken a new pace to create more variability by combining both recombinations with induced mutation through gamma rays irradiation. For this purpose, the F_(2) seeds were irradiated with gamma rays at BARC, Mumbai and sown to grow the F_(2)M_(1) generation and subsequently the superior mutant lines with high degree variability with high GCV and genetic advances were selected from F_(2)M_(2) generation of the mutant population.
