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 viz., DBW39, DBW16 and DBW14 had lowest HSI (0.34-0.36) for plot yield and were considered as heat tolerant genotypes by, both, HCA (Hierarchical Cluster Analysis) as well as DA (Discriminant Analysis). These genotypes may serve as potential donors in wheat breeding to improve the terminal heat tolerance.

面包小麦（Triticum aestivum L.）的耐热性评价

对34个小麦基因型的耐热性进行了两年的分析。在14个性状中，冠层温度、小区产量和抽穗天数是基因型聚类的主要组成部分。三个基因型，即DBW39、DBW16和DBW14，小区产量的HSI最低（0.34-0.36），并且被HCA（层次聚类分析）和DA（判别分析）都认为是耐热基因型。这些基因型可作为小麦育种的潜在供体，以提高小麦的最终耐热性。
