During kharif 2018, a study on genotype x environment interaction for grain yield in Pearl Millet (Pennisetum glaucum L.) was carried out using a randomized block design with three replications in three artificially created environments having varied doses of fertilizers. A total of eighteen hybrids were chosen to estimate their stability with respect to different morphological characters as well as identify the best hybrid with respect to high yield. The environment indices for all the characters, were found in between -2.85 (environment-III) and 1.76 (environment-I), indicating an enough diversity provided to run the experiment satisfactorily. The average seed yield was found maximum in KBH-108 (30.73g) and minimum in MARU-TEJ (23.17g). Of them, our study has realized MPMH-17as the most stable hybrid followed by HHB-197, and RHB-177 with respect to grain yield in all three different environments. The environments exhibited a linear effect on mean grain yield, with the lowest value under environment-III. In HHB- 197 and MPMH-17, consistent grain production was found in all the environments. Seed yield stability was found below average in RHB-223, HHB-299, and 9001, alluded their need of favorable environmental conditions to perform satisfactorily. Whereas, hybrids RHB-233, HHB-67,GHB-744, and 9450 have shown seed yield stability more than the average value, disseminated their capability to survive even in the difficult climatic conditions.
