The variety showed 36.57, 19.96, 9.11, 23.53 and 26.38 per cent higher yield over the respective checks in station, state, national, agronomical and adaptive trials, respectively. It showed excellent milling (70.30 %), head rice recovery (66.19 %) and good cooking qualities (Amylose content 25.43 %). Ratnagiri 6 rice variety showed moderately resistant to leaf blast and bacterial leaf blight diseases and moderately resistant to stem borer, leaf folder and gall midge at endemic sites.
