Rice is grown in many different ecosystems. Iron and zinc deficiencies have been reported to be a food-related primary health problem affecting nearly two billion people worldwide. The brown and red rice genotypes have high grain iron and zinc content and attempt was made to study the heterosis for these traits along with grain yield. Forty eight rice hybrids developed by line × tester mating design involving 6 lines and 8 testers were evaluated for heterosis over better parent and standard variety, Swarna and Chittimutyalu for ten characters. Two hybrids exhibited positive heterosis over standard variety, Chittimutyalu for grain iron content and fourteen hybrids recorded positive significant heterosis for grain zinc content over standard variety, Chittimutyalu. For grain yield, thirty six hybrids exhibited positive significant standard heterosis over standard variety, Swarna.
