ABSTRACT
F3 and F4 lines of the cross between DWR 162 X NIL PBW 343 were evaluated for yield and leaf rust resistance. The genetic variability studies in F3 generation indicate high mean and wider range for all the traits under evaluation. High PCV (phenotypic coefficient of variation) and moderate GCV (genotypic coefficient of variation) were recorded for the traits number of tillers per plant and grain yield per plant. In F4 generation high PCV (phenotypic coefficient of variation) and moderate GCV (genotypic coefficient of variation) were recorded for the traits, number of tillers per plant and grain yield per plant. ). For leaf rust infection, high PCV and GCV, moderate heritability and high GAM was recorded.
Key words: Triticum aestivum L., Leaf rust resistance, Recombinant lines, PCV and GCV.
