Progenies from a cross between ‘Gopaldoddiga’ and ‘ARB6’ cultivars were selected on the basis of combining ability analysis to study the genetics of transgressive segregation for zinc content and agronomic traits using augmented designs. Results revealed the presence of general combining ability and specific combining ability effects, and the parents were found to be good general combiners for zinc in grains, 100 grains weight and grain yield per plant. Higher phenotypic and genetic coefficients of variation for all characters, and high heritability coupled with high genetic advance for most of the traits indicates strong additive genetic control of these traits. Presence of positive relationship between grain yield and grain Zn concentration implies these traits can be used as a selection criterion from F4 generation onwards. These zinc enriched high yielding hybrids can be effectively utilized in the rice biofortification programs.
