An experiment was conducted to evaluate the genetic diversity in 48 genotypes of wheat for 25 traits under two environments i.e., timely and late sown conditions, at Wheat and Barley Section, Department of Genetics and Plant Breeding, CCS HAU, Hisar during rabi, 2019-20. The genetic diversity analysis revealed the formation of seven clusters in both environments. Based on the genetic distance, it was concluded that crossing of genotypes from cluster V with clusters I and IV to get a broad spectrum of variation for both environments. Cluster VII for timely sown and cluster V for late sowing conditions contained genotypes with high mean performance for grain yield and other traits and therefore these genotypes can be utilized for yield improvement. Based on the analysis of percent contribution of different traits to total genetic divergence, it was found that under timely sown condition CTD 1, total gluten content and for late sown condition zinc content, CTD 2 contributed the most.
