摘要/Abstract

摘要：以2个广亲和品种(轮回422，02428)分别与籼、粳稻配组及粳/籼、籼/粳、粳/粳配组，检测了杂种F1代的结实率及镜检亲本F1代的花粉活性.试验结果表明：除测49外，亲本花粉可育性均较高，杂种F1代的花粉育性因亲本不同而有所差异，以广亲和品种与籼、粳稻配组所得的杂种F1代的花粉可育性最高；籼粳杂种F1代的花粉败育率与植株不结实率的相关系数达0.838 0.

Abstract: Wide compatibility rice varieties(WCVs) LH422 and 02428,Indica and Japonica rice varieties were used in this test with cross-combination types.The seedset values of F1 hybrids were determined,and the pollen activities of the parent lines and F1 hybrids were also inspected with microscope.The results showed that the pollen fertilities of the parent lines reached a competitive higher level except those of Ce49,but the pollen fertilities of F1 hybrids varied according to their parent lines.The pollen fertilities of F1 hybrids which were cross-combined by WCVs and Indica or Japonica rice varieties were the highest among all the combinations.The correlation coefficience of the pollen sterilities and the unfilled grain rate reached 0.838 0.

Key words: WCVs, seedset, pollen activities, F1 hybrids
