Abstract
The present study entitled “study of stability parameters for seed yield and its components in mung bean (Vignaradiata L. Wilczek)” was undertaken at research farm, college of agriculture, SKRAU Bikaner to understand the role of genotype and environmental interactions in expression of various characters and stability of twenty five mung bean genotypes. The experimental material was raised in randomized block design with three replications under three environments which were created by three different dates of sowing during kharif 2011-2012. A joint regression analysis of variance revealed that variances due to genotype, environment, genotype x environment (linear), and E + (G x E) were found significant for all the traits. G x E interaction was also found significant for all the characters except plant height and pod length. Non-linear component of genotype x environment interaction was found significant for branches per plant, number of effective pods per plant, 1000-seed weight, harvest index, protein content and seed yield per plant. On the Basis of stability parameters the genotype RMG-116 was found better in per se performance and stability for seed yield,this genotype can be recommended for commercial cultivation and can also be effectively utilize in the future breeding programsfor development of stable variety.
