Abstract: The present research work comprises sixty advanced lines of wheat, collected from Wheat Improvement Project, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur. These genotypes were evaluated in a randomized complete block design (RCBD) with three replications at Seed Breeding Farm, Department of Genetics and Plant Breeding, College of Agriculture, Jabalpur during Rabi 2016-17. The presence of genetic divergence among these lines was observed by Mahalanobis’s D² statistic. All the accesses were grouped into five distinct clusters. The highest number of genotypes appeared in cluster I (45) followed by cluster III (8) and cluster IV (5) while the lowest numbers of entries were reported in cluster II (1) & V (1). Principal component analysis (PCA) indicated that the seven principal components (PC1 to PC7) showed 66.22% of the total variability. The highest value of yield and its attributing traits were present in PC3, PC2, and PC1 respectively, whereas PC4 & PC7 were related to quality traits.
