| 摘 要： | 利用4个粳稻BT型不育系和5个新选粳稻BT型同质恢复系及4个非同质恢复系通过NCⅡ设计共配36个组合，对杂种一代8个农艺性状和10个品质性状的表现及亲本的配合力进行了研究。结果表明：（1）除播抽历期、千粒重和单株有效穗三性状外，同质恢复系所配杂种的其他农艺性状与非同质恢复系所配杂种相比，均有所降低，但就单株产量而

| Abstract: | Seven million hectares are planted with japonica rice in China yearly. The area of japonica hybrid rice planted annually was less than 10% though the first commercial hybrid cultivar was released in 1975. The major reasons for this situation are that heterosis over pure line check cultivar is not co |
