In each environment, these genotypes were planted in randomized complete block design with three replications. Data were recorded on grain yield per plot in gms. The analysis of variance for yield in individual and pooled analysis showed highly significant differences among the genotypes and environments for grain yield, indicating the presence of variability among the genotypes as well as the environments under study. The genotype x environment (G x E) interaction was further partitional into linear and non-linear (pooled deviation) components. Mean squares for both these components were highly significant, indicating that the both predictable and unpredictable components shared G x E interaction. Amongst the indigenous rice genotypes of Nagaland Mekniya Khol, Kuki Chaushi, Petkoti, Nyuceimo Thevuru (Kelo-u), Kemony Kehnau (white), and Teke exhibited average stability and higher grain yield and are ideal for general recommendation. 收起
