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

Published on

Genetic divergence in 51 genotypes of spring wheat (40 advanced lines and 11 standard
checks) was assessed using DZanalysis. Clustering was 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 of DZstatisticatTocher's values SOO and 300. Protein content exhibited
maximum contribution towards total divergence followed by phenol colour reaction and
peduncle length.
 

Keywords: Genetic divergence, Tocher's value, minimum spanning tree, linkage dendrogram, T. aestivum.
