Heat stress in wheat bears very high significance in Realsing yield potential of a genotype. Terminal heat stress in particular affects the wheat yields considerably. Keeping this in view the present investigation was carried out with 32 diverse genotypes of bread wheat in completely randomized block design with 3 replications at G.B. Pant University of agriculture & Technology, Pantnagar for studying the genetic diversity for terminal heat stress tolerance under late sown condition. The observations were recorded on 16 agronomic traits and 3 physiological traits. The statistical analysis for genetic divergence was done using Mahalanobis-D2 statistics and clustering of genotypes was done using Tocher method. On the basis of genetic diversity analysis, it was found that the maximum percent contribution towards genetic divergence was from grain yield/plot i.e. 47.98% and minimum by the harvest index (0.81%). Clustering of genotypes revealed that clusterI and III have maximum number of genotypes (14) and clusters-II, IV, V & VI each has single genotype only. The highest intra-cluster distance was exhibited by cluster-III (703.41) revealing maximum genetic divergence among its constituents. The highest inter-cluster distance was found between clusters-V and VI (7190.38). The nineteen genotypes were found tolerant. The genotypes bearing desired values from different clusters can be exploited in future breeding programme for improving the yield and physiological traits under late sown condition for mitigating the threat of terminal heat stress in bread wheat.
小麦的热胁迫对基因型产量潜力的影响非常大。终端热胁迫对小麦产量的影响尤为显著。有鉴于此，本研究在潘特纳加 G.B. Pant 农业与技术大学对 32 个不同的面包小麦基因型进行了完全随机区组设计，3 次重复，以研究晚播条件下耐受终期热胁迫的遗传多样性。观察记录了 16 个农艺性状和 3 个生理性状。利用 Mahalanobis-D2 统计法对遗传差异进行了统计分析，并利用 Tocher 方法对基因型进行了聚类。在遗传多样性分析的基础上，发现对遗传差异贡献最大的是谷物产量/地块，即 47.98%，最小的是收获指数（0.81%）。基因型的聚类显示，聚类 I 和 III 的基因型数量最多（14 个），而聚类 II、IV、V 和 VI 只有一个基因型。簇内距离最大的是簇 III（703.41），表明其组成成分之间的遗传差异最大。聚类 V 和 VI 之间的聚类间距最大（7190.38）。发现 19 个基因型具有耐受性。在未来的育种计划中，可以利用不同聚类中具有期望值的基因型来提高晚播条件下的产量和生理性状，以减轻面包小麦终期热胁迫的威胁。
