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

Abstract

Genetic divergence in 51 genotypes of spring wheat (40 advanced lines and 11 standard checks) was assessed usingDZanalysis. Clusteringwas done using three different Tocher's values, i.e. lOGO, 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 ofDZstatistic atTocher's values SOO and 300. Protein content exhibited maximum contribution towards total divergence followed by phenol colour reaction and peduncle length.
