This dataset contains 15 question-and-answer pairs derived from a study on terminal heat tolerance among wheat genotypes conducted at Bihar Agricultural College during the winter season of 2021–22. The research evaluated 225 wheat genotypes under normal and heat stress conditions using multivariate analysis and selection indices. Key methods included D2 statistics, principal component analysis, and the heat susceptible index (HSI). The study aimed to identify climate-resilient wheat genotypes by analyzing traits such as grain filling duration, 1000-grain weight, and yield.

| Which cluster contained the largest number of wheat genotypes studied for 16 traits? | cluster V with 51 genotypes | The clustering pattern as per Tocher’s optimization method and magnitude of D2value revealed that wheat genotypes studied for 16 traits were grouped into seven clusters, where cluster V with 51 genotypes emerged as the largest cluster. Cluster VII and cluster III showed highest inter-cluster distance (6.958). HSI for grain filling duration (GFD), 1000 grain weight (TGW) and yield per plot (YPPT) ranged from 0. (genotype 30, GID: 7933202) to 2. (genotype 54, GID: 7933656), -0. (genotype 44: GID: 7933473) to 2. (genotype 36, GID: 7933333) and -0. (genotype 37 GID: 7933334) to 1. (genotype 49, GID: 7933509), respectively. Genotypes 88, 74 and 66 showed low HSI for GFD, TGW and YPPT, respectively. Six principal components (PC1 to PC6) accounted for 76.38% of the total variation and represented the core traits for further investigation. | 176 | factual | 0.570 | https://epubs.icar.org.in/index.php/IJAgS/article/view/143443 | The clustering pattern as per Tocher’s optimization method and magnitude of D2value revealed that wheat genotypes studied for 16 traits were grouped into seven clusters, where cluster V with 51 genotypes emerged as the largest cluster. | ||||
