Abstract:

A set of sixteen inbred lines were evaluated to assess the ability of inbred lines, they were crossed in half diallel mating design. A total of 120 single cross hybrids were developed and evaluated in simple lattice square design at K block experimental plots of Department of Genetics and Plant Breeding, University of Agricultural Sciences, Bengaluru. The observations were recorded on five randomly selected plants. Analyses of variances revealed that, all the hybrids were differed significantly for the traits under consideration which indicates the presence of genetic variability. The SCA variance was higher than the GCA variance, indicates the presence of both additive and non-additive gene action controlling the grain yield and its attributing traits. The inbreds with positive significant GCA can be used as parents in hybrid development program, whereas, the hybrid combinations with significant SCA have to evaluate across different locations to know its genetic potential.
