摘要: 偏籼型籼粳交迟熟种“满仓515”具有大穗大粒特性,高抗稻瘟病,并对光温反应不敏感。1996年通过福建省审定,在1994、1995两年福建省产量区域试验中,满仓515比对照荆糯6号和汕优桂32分别增产8.17%和8.26%.该品种选育成功表明杨守仁教授“理想株形与优势利用相结合”在偏籼型亚种间杂交育种的实现。Abstract: Mancang 515”,a newly bred long duration(136 d) indicajaponica cross,possesses the traits of large panicles and heavy grain weight.It shows highly resistant to blast and is nonsensitive to photo temperature.It was registered and released in 1996 in Fujian province.In yield trials in 1994-1995 in northern Fujian,it averaged 8 17% more than Jinruo 6 and 8 26% more than Shanyougui 32.The research indicated that the breeding theoty about “ideal plant morphology combining with dominancy utilization” presented by Prof.Yang Shouren has been proved in the screening indica cline rice of indica japonica hybridization.
