| 摘 要： | 利用甘蓝型油菜隐性核不育系ZWAB及临保系和恢复系分别配制了临保三交种、单交种进行组合的杂种优势比较,结果表明:临保三交种在抗性方面优于单交种,在经济性状及产量上与单交种相当。临保三交种完全可以替代单交种,从而节省了两系制种过程中初花期拔除50%可育株的环节,降低了劳动强度和成本,提高了制种产量和种子纯度。

| Abstract: | Comparison of recessive genetic male sterile ZWAB of Brassica napus L.temporary-maintainer triple and single cross hybrids.indicated that there were significant differences in resistance and no difference in economic characters or yield between temporary-maintainer triple and single cross hybrids.The temporary-maintainer triple hybrids can be commercially used instead of single cross hybrids.it did not need to get rid of 50% male fertile plants in producing hybrid seeds,and lowed the cost and work force,improved the yield and purity of hybrid seeds production. |
