Abstract:

The present experiment was carried out using twenty-nine elite breeding lines from Station Yield Trial - Slender Grain materials along with three check varieties at the Rice Research Station, O.U.A.T., Bhubaneswar in kharif- 2016. A part of the research was to study the genetic divergence among the breeding lines used in the experiment. The D2 values obtained from the divergence study ranged from 3.36 between OR2675-6-4 and OR2676-2-5 to 2518 between OR2675-2-1 and Samba mahsuri. Following Tocher’s method, all the thirty-two genotypes were classified into five different non-overlapping clusters. Cluster I contained twenty genotypes, Cluster II & III contained five genotypes each while cluster IV & V contained check varieties Ranidhan and Samba mahsuri respectively. The graph constructed by canonical analysis were broadly in agreement with the magnitude of divergence measured by D2 statistic, thus very well corroborating the grouping by Tocher’ s method. Selection of parents should be done from the more divergent clusters for future hybridization program for getting better segregants.
