83-49 Department of China Rice Research Institute cultivated into a new variety of early maturing rice. In 1988, the county introduced the trial planting and participated in the early-maturing medium-yielding group experiment. The average yield per mu was 465 kg at 6 spots, ranking the first place; the yield was 7.7% more than that of the control variety 73-07. On the basis of successful trial planting in 1989, it took 1750 kg of seeds and planted more than 200 acres of land. After field investigation and production acceptance, the average yield per mu was 457.5 kilograms. In medium-ripening group than in the test, still ranked first; than the control varieties 73-07 yield 7.95%. Special features: The variety is medium maturing varieties, the whole growth period of about 116 days. Seedling leaves dark green leaves upright, plant compact, strong tillering; late fall color is good, not premature. Plant height of 79 cm, tillering into high spikes, large grains, spike
