摘要 博优315是利用博A与自选恢复系测315配组而成的感光型晚籼新组合。全生育期122d左右,分蘖力较强,有效穗270~300万/hm^2。每穗总粒数142粒,结实率79.8%左右,千粒重22.3g。耐肥抗倒,后期耐寒性中等,米质较优。一般产量7.5t/hm^2,高产可达8.55t/hm^2以上。截至2005年巳在桂南稻作区累计推广种植3.3万hm^2以上。 Boyou 315 is a new photo-sensitive type combination, which was bred through a crossbreeding between 13o A and optional restorer llne Ce 315. It is characterized by strong tillering ability, strong toleranee to exessive fertilization rate and lodging, medium cold tolerance and good grain quality. The whole growth duration is about 122 days, the effective panicle per ha is 2.7-3.0 million, the grains per panicle were 142, and the seed-setting rate is 79.8%, and the 1000-grain weight is 22.3g. The general yield of Boyou 315 is 7, 5 ton/hm^2 and the highest yield was 8. 55 ton/hm^2. A total cultivated area of Boyou 315 was over 33,000 hm2in South of Guangxi by the year 2005.
