| 摘要: |
| 玉米异细胞质MO17雄性不育系籽粒产量的配合力无显著差异，雄性不育的MO17与可育MO17的配合力也无显著差异。直观看，穗长等农艺性状的表现也基本一致。因此，在玉米杂种优势利用中，可用异细胞质MO17雄性不育系组配同一个杂交种，不会因利用单一的雄性不育细胞质而带来潜在性的危险。 |

| Abstract: |
| There is no significant difference in the combing ability of grain yield of MO17 male-sterile lines with different cytoplasmw in maize,and also in the combining ability of grain yield of MO17 male-sterile lines and MO17 fertile lines.As viewed intuitionally,the ear length and other agronomic traits are basically in the uniformity.As a result,in using the hybrid vigors in maize,the same hybrid could be obtained by using MO17 male sterile lines with different cytoplasms in the combination; and thus,it is impossible to bring about the latent disaster of danger by using only one kind of male-ster-ile cytoplasm. |
