| 摘 要： | 以广亲和品种轮回422，02428分别与籼、粳稻配组及粳/籼、籼/粳、粳/粳配组，检验杂种F1代的杂种优势与育性，试验结果表明M-201/日本优的每株穗数和单粒株重优势明显，广亲和品种与籼、粳配组能得到具有生物优势而且育性强的杂种F1代，显著提高水稻产量；轮回422为亲梗型的广亲和品种，但02428对籼稻有较强的亲和力.

| Abstract: | The F 1 heterosis and fertility of combinations of LH422 or 02428 with Indica or Japonica and combinations of Indica with Japonica were inspected in this test. The results showed that F 1 of M-201/Nihonmasari had a quite stronger heterosis on tillers per plant and grains weight per plant, F 1 of WCVs with Indica or Japonica were of higher heterosis and of stronger fertility and would promote the rice output obviously, and LH422 had a stronger tendentiousness to Japonica, but 02428 has also a strong tendentiousness to Indica. |
