Abstract: The current study aimed to identify stable genotypes across eight environments, as the performance of genotypes can vary across different locations. A multi-environment experiment was conducted, involving 29 pearl millet genotypes with three replications, at eight locations in India (ARS Mandor, Bikaner, RARI Jaipur, Jamnagar, Hisar, Gwalior, Ranchi, Jammu and Kashmir) for one year (2019). Each location consisted of nine morphological characters. The data were obtained from ICAR-All India Coordinated Research Projects (AICRP) of pearl millet, Agricultural University, Mandor, Rajasthan, India. The stability of genotypes was evaluated using the Eberhart & Russell model (1966). The stability analysis, based on combined ANOVA, indicated significant differences between genotypes (G), environments (E), and genotype x environment interactions (G X E). None of the genotypes were stable for all characters. The results showed that genotypes G14, G12, G10, G19, G11, G15, G21, G23, G20, G29, G27, G22, and G29 were determined to be stable for the majority of pearl millet characters. The adaptability of genotypes to favorable, unfavorable, and stable environments was also assessed.
