GENETIC DIVERGENCE ANALYSIS IN SPRING WHEAT (T. AESTIVUM L.)

Genetic divergence in 51 genotypes of spring wheat (40 advanced lines and 11 standard checks)was assessed using D2 analysis. Clustering was done using three different Tocher's values, i.e. 1060, 500 and 300 and genotypes were grouped into 7, 9 and 10 different clusters, respectively. Linkage dendrogram and minimum spanning tree exhibited confirmity with the clustering pattern of D2 statistic at Tocher's values 500 and 300. Protein content exhibited maximum contribution towards total divergence followed by phenol colour reaction and peduncle length.
