Abstract
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
