Identification of transgressive segregants with high zinc in grains under aerobic condition in F4 population of rice (Oryza sativa L.)

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.
