Abstract: Crop varieties developed should exhibit stable performance under various environmental conditions, especially in a diverse country like India, where a wide range of environments exist. Developing genotypes with a potency of adjustability across a broad spectrum of environmental conditions is essential for effectively realizing their inherent potential. Therefore, research aimed to estimate the magnitude of genotype, environment, and genotype-by-environment interaction for seed yield and its component traits in mungbean. Fourteen genotypes of mungbean were evaluated from four different environments in Madhya Pradesh. The experiment was regulated in the experimental areas of the All India Co-ordinated Research Project on MULLaRP, R.A.K. College of Agriculture in Sehore, Krishi Vigyan Kendra Barwani, Krishi Vigyan Kendra Jhabua, and the College of Agriculture in Gwalior, during kharif 2021. The mungbean was grown using a Randomized block design with three replications, and the data were subjected to stability analysis following the model suggested by Eberhart and Russell (1966). The stability performance of genotypes RVSM 22-6 and IPM 205-7 (Virat) exhibited average stability for major yield-contributing traits. Hence, these genotypes may be fitted for cultivation in different environments. Stability analysis is a crucial tool in plant breeding for predicting the performance of various genotypes across changing environments.
