The present study aimed at investigating genotype × environment interaction and stability performance for yield component traits of sixteen aromatic rice genotypes over six kharif seasons to find agronomically stable genotypes. The analysis of variance for yield component traits revealed highly significant (p <0.01) variation among genotypes, environments and their interactions for yield traits. Based on univariate analysis of YSi and Eberhert and Russel model for grain yield genotypes, Kalabati (G5), Dudheswar (G1), Mohan Bhog (G6), Krishna Bhog (G7), Dehradun Gandeswary (G8), Ramachandra Bhog (G9), Katharibhog (G11) and Tulaipanji (G13) exhibited high mean as compare to population mean. The highest ranked and YSi score genotypes G11 and G5, were found best for the yield component traits. Based on the AMMI biplot technique, the genotypes G13, G2 (Lal Badsha Bhog), and G7 were most appropriate in the entire environment (season), while the GGE biplot indicated that G5 was the most suitable for grain yield

Recent predictions on climate change indicate that episodes of unseasonal rains, cold stress, and high temperatures are expected to impact rice production and productivity. To obtain consistent yield across diverse environments, a rice variety should have adaptability and stability to fit into various growing seasons and locations. In the present investigation, AMMI model was employed to assess the stability of nine rice genotypes of the early maturity group across two summer and rainy seasons. Combined analysis of variance expressed a significant genotype, environment and genotype × environment interaction for grain yield and days to 50% flowering. The study also suggested environmental effect as the greatest part of the variation, followed by genotypic and genotype × environment interaction effects for these traits. Biplots and statistics of AMMI identified that G1, G3 and G5 were the most stable and adapted high yielding rice genotypes, while G9, G4 and G6 appeared to be the most stable genotypes with earliness. Hence, these genotypes could be used as directly as varieties or as donors in future breeding programmes for improving rice productivity in the early maturity group after evaluation under multi-location trials.
