摘要

Objectives of this research were to assess genotype environment interaction and determine stable oat (Avena satiua L.) cultivar in Kashmir division over three locations for grain yield and its components in 10 genetically diverse genotypes using randomized block design. There was considerable variation in grain yield within and across environments. Stability analysis for grain yield was conducted to check the response to genotypexenvironment interactions. The mean squares due to GxE (linear) were significant depicting genetic differences among genotypes for linear response to varying environments. Mean squares due to pooled deviations were highly significant, reflecting considerable differences among genotypes for non-linear response. Out often genotypes, only two oats lines i.e., Sabzaar and SKO-208 showed non-significant deviation from regression and their regression coefficient values were close to unity classified were desirable for grain yield across the environments. The cultivar, "SKO-208" with respective regression coefficient value of 1.011, the smallest deviations from regressions (S~2di) value and the highest grain yield could be considered the most widely adapted cultivar. The other test cultivars were sensitive to production-limitingfactors, their wider adaptability, stability and general performance to the fluctuating growing conditions within and across environments being lowered.
