Studies on Genetic Diversity and Principal Component Analysis in Wheat Germplasm (Triticum aestivum L.)

This study aimed to assess the potential genetic diversity among wheat genotypes by using cluster analysis and principal component for selection of desired parents in hybridization programmes. The was carried out at Crop Research Center, Department Agriculture, Himgiri Zee University, Dehradun, Uttarakhand, during Rabi season 2021-2022 under irrigated conditions. Twenty germplasm lines (Triticum aestivum L.) were grown Randomized Block Design with three replications an objective variability through D2 statistics wheat. Analysis variance revealed significant differences all traits studied indicating that presence material study. clustering pattern as per Tocher’s optimization method obtained on basis magnitude value twenty grouped into five clusters. maximum intra observed I (130.89) followed II (108.06) III (97.93). inter distance values ranged from 249.44 1101.59. between IV (1101.59) (1017.07) indicated wide divergence existed these From results Principal six components PC 1 PC6, which are extracted original data having latent roots greater than one thereby accounting 84.30% total variation.
