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。 The results showed that the three crossbreds of Linbao were superior to those of the three crossbreds of Linbao, In monoculture, the economic traits and yields are comparable to those in monoculture. Linbao three crossbreed can replace single crossbreed completely, thus saving 50% of the fertile plants at early flowering stage during the two-line seed production, reducing labor intensity and cost, and improving seed production and seed purity.
