摘要:
甘蓝型油菜引入我国历史较短,遗传基础狭窄,为了拓宽其遗传基础,前人对其开展了大量的远缘杂交研究。本文总结了甘蓝型油菜与芸薹属植物、其他十字花科植物远缘杂交研究利用进展。甘蓝型油菜种间杂交已创制出早熟、黄籽、抗病等新材料,甘蓝型油菜属间杂交已导入抗旱性、抗寒性、乳白花等优良性状。甘蓝型油菜远缘杂交还选育出新的不育系、附加系、代换系。对甘蓝型油菜远缘杂交的发展方向进行了探讨。

Abstract:
Brassica napus had been cultivated in China since 1930s, but the Chinese modern cultivars represented a narrow genetic basis. In order to enrich the genetic diversity in gene pool, distant hybridizations with relative species have been conducted. This paper summarizes recent advances on distant hybridization in Brassica napus with other Cruciferae plants. These novel germplasm resources showing early maturation, yellow seed or disease resistance, have been generated by inter-species hybridization in genus Brassica. The elite alleles on traits of drought resistance, cold resistance or milky white flower, which were identified from other genus, have been introgressed into Brassica napus. We further proposed the focus on distant hybridization in Brassica napus in future.
Key words:  Brassica napus  Brassica spp., interspecific hybridization  intergeneric hybridization  germplasm enhancement
