Stress tolerance and adaptation as criteria for evaluating top rice genotypes in both typical and water-limited settings

Abstract

The results showed that compared to irrigated circumstances, crop height, effective panicles per m², and grain

production were all 22% lower under moisture-restricted conditions. Among the strains tested, IR17L1387,

IR16L1713, and IR16L1801 had the best stress tolerance index (STI), suggesting that they might thrive in

environments with limited water availability. Sukhadhan 3 genotype showed the highest degree of stability in

both settings, according to GGE biplot analyses (Which-Won-Where and Mean vs. Stability). Furthermore,

under conditions where moisture was scarce, the winning genotype was IR16L1713, while in conditions where

water was abundant, the winning genotype was IR17L1387.
