Abstract


MGR (CORH1) rice hybrid was developed using cytoplasmic genic male sterile line, maintainer line and restorer line (A/B/R). The parentage of this hybrid is IR 62829 A/IR10198-66-2R. This matures in 110-145 days, grows to a height of 75 cm and tillers profusely under a wider spacing of 25 x 10 cm. The average grain number is 150 per panicle and 1000 grain weight is 20 g. It gives one tonne more yield per hectare over IR 50. The grain is medium slender, straw coloured with white rice. This is best suited for May-June and December - January sowings in Tamil Nadu.
