Abstract:

The rice variety Ratnagiri 7 (Red rice; RTNRR-4) was evolved through the mutant selection from MO17. The above variety is midlate in duration (122-125 days), Semi-dwarf (100-110 cm plant height), short bold grain type. The variety showed 46.50, 21.40, 50.96 and 59.41 per cent higher yield over the respective checks in station, state, agronomical and adaptive trials, respectively. Ratnagiri 7 (RTN RR-4) recorded 23.88%, 18.69% and 39.40% higher grain yield over IR-64, BPT-5204 and Kalanamak respectively in AICRIP trials. RTN RR-4 consists of 28.50% (17.35 ppm) and 32.7% (7.9 ppm) high iron content over the check Bela (13.5 and 5.95 ppm) in brown and polished rice respectively. Ratnagiri 7 (RTN RR-4) consists of 42.82% (28.35 ppm) and 43.0% (24.25 ppm) high zinc content over the check Bela (19.85 and 16.95 ppm) in brown and polished rice respectively. It also having low glycemic index (53). RTNRR-4 having high milling (64.17%) and head rice recovery percentage (60.65%) with good cooking quality. It recorded average yield of 4.5 to 5.0 t/ha. It showed resistant reaction to stem borer, leaf folder and gall midge and moderately resistant to leaf blast, bacterial leaf blight. Therefore the rice variety Ratnagiri 7 recommended for release for commercial cultivation in Konkan region of Maharashtra in the year 2017.
