育种实践证明 ,以广谱广亲和光温敏核不育系培矮 64S为母本 ,性状优良的典型粳稻为父本 ,选育产量高、品质优、抗性好的两系亚种间杂交粳稻组合是可行的。并从利用籼粳中间型光温敏核不育系 ,加强广亲和系的选育和引进理想株型育种方面对选育两系亚种间杂交粳稻进行了探讨 Breeding practice has proved that a broad-spectrum broad-compatible and thermo-photo-sensitive genic male sterile line Peiai 64S was used as the female parent. The typical japonica rice with good traits was used as the male parent. Breeding of two-line subspecies with high yield, good quality and good resistance Japonica rice combinations are feasible. The breeding of two-line intersubspecific hybrid japonica rice by using indica-japonica intermediate photo-thermo sensitive genic male sterile line, strengthening the breeding of wide compatibility line and introducing the ideal plant type breeding
