Abstract

Terminal heat tolerance of 34 wheat genotypes were analyzed for two years. Among 14 traits, canopy temperature, plot yield and days to heading were major components in clustering of genotypes. Three genotypes namely, DBW39, DBW16 and DBW14 had lowest heat susceptibility index (0.34-0.36) for plot yield and were considered as heat tolerant genotypes by both Hierarchical Cluster Analysis as well as Discriminant Analysis. These genotypes may serve as potential donors in wheat breeding to improve the terminal heat tolerance.
