Evaluation of bread wheat (Triticum aestivum L.) for terminal heat tolerance

Published on

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.
