Abstract

In the present study, twenty-nine genotypes were carried out to determine the stability of morphological characters viz., dry fodder yield, Days to 50% flowering, and Days to maturity of pearl millet in eight different environments viz., ARS Mandor, Bikaner, RARI Jaipur, Jamnagar, Hisar, Gwalior, Ranchi and Jammu Kashmir using Freeman and Perkins model. Data was collected from ICAR- All India Coordinated Research Projects (AICRP) of pearl millet, Agricultural University, Mandor, Rajasthan, India for one year (2019). The combined analysis of variance showed significant differences among genotypes, environments and Genotype by Environment (G x E) interaction for all morphological characters under study. Mean, regression coefficient and deviation from regression were used as stability measures. Genotype G23 exhibited stability across all studied traits, while G10 and G29 demonstrated stability specifically for dry fodder yield and days to 50% flowering. Furthermore, genotype G22 displayed stability for dry fodder yield and days to maturity in all environments.
