Hainan early growth and special indications accounted for 25%, 77 days longer than the hybrid 77, shorter than the II you 128, late Hainan made Ⅱ You 128 short 7d; Hubei for a quarter of the whole growth period than Ⅱ You 725 short 9.5d ; Mianyang, Sichuan Province, a quarter shorter than Shanyou 63 short 2d; Hunan, Jiangxi for double late growth period than Shanyou 46 short 2 ~ 3d. Plant height 105 ~ 115cm, spike length 22.5cm, effective spike 3 million / hm ~ 2, about 170 grains per spike, seed setting rate of about 82%, grain weight about 24g, strong tillering, effective spike, leaves Spike, moderate plant type, ripe maturity good color. In 2004, he took part in the regional trial of early quality aroma rice in Hainan Province, with an average yield of 8772kg / hm ~ 2, ranking No. 2 and bit of indica accounting for 25%
