摘　　要：水稻群体育种是以光温敏核不育水稻为遗传载体,借助它的生态不育特性,建立多亲本天然授粉的杂交群体。在F2、F3……进行生态育种和常规育种的双向选择,即选择优良不育株,育成新的光温敏核不育系。选择可育株,育成新的常规水稻品种。在F2、F3……代收取不育株的天然杂交种,构建新一轮杂交群体。作者利用群体育种技术已育成通过辽宁省审定的粳型水稻光敏核不育系GB028S和常规水稻品种盐丰47。Rice colony breeding is use the rice which is sensitive to light temperature and karyon is no-breeding as genetic carrier,in virtue of it`s zoology no-breeding,building up mul-parent`s hybridized colony which is self-pollination.Make double choice at zoology breeding and general breeding during F2,F3......Choose excellent no-breeding plant ,breed it to new series which is sensitive to light temperature and karyon is no -breeding.At the same time choose breeding plant ,breed it to series which is general breeding.Choose self-hybridized seed that no-breeding from F2,F3......to build a new hybridized colony.Use the colony breeding technology author has breed the rice named GB028S and Yanfeng-47that had examined and approved by liaoning province.
