ASSESSMENT OF TRANSGRESSIVE SEGREGANTS FOR YIELD AND YIELD ATTRIBUTING TRAITS IN MUNG BEAN (VIGNA RADIATA (L.) R. WILCZEK) IN F3 GENERATION

This study aimed to estimate transgressive segregants in nine mung bean genotypes.The genotypes included four crosses and five parents.Eight morphological traits were examined.The experiment was conducted during the Kharif season of 2022 at the Research Farm of Sri Karan Narendra College of Agriculture, Jobner, Jaipur.A randomized block design with three replications was used.Transgressive segregation in desirable directions was observed for all traits in the F 3 generation of the crosses.The highest proportion of transgressive segregants was found for pods per plant.Other traits with high transgression included plant height, pod length, clusters per plant, seed yield per plant, 100-seed weight, seeds per pod, chlorophyll content, and pods per cluster.The study concluded that transgressive breeding is effective when desired trait intensity is absent in the parents.This method accumulates favorable genes from both parents.In many cases, the better-parent yield was surpassed, along with improvements in other traits.Significant transgressive segregants for major agronomic traits were observed.MH 421 RMG 975 showed the highest proportion of desirable segregants.These segregants exhibited substantial improvements in yield.Seed yield per plant increased by up to 52.14% compared to the best parent.The findings show the potential of transgressive breeding to improve green gram productivity.
