中文摘要:
      为研究青藏高原白菜型油菜与甘蓝型油菜远缘杂交的亲和性,对白菜型油菜与甘蓝型油菜 及配制的正反交组合的杂交结实率和亲和指数进行测定,并对杂交 F1 代形态学、花粉活力和自交亲和性 分析。结果表明:白菜型油菜与甘蓝型油菜杂交,以甘蓝型油菜作母本,结实率和亲和指数较高;甘蓝 型油菜与白菜型油菜正反交 F1 代组合均表现为自交亲和,植物学性状均偏向于母本,自交亲和性表现为 甘蓝型油菜 > F1(甘蓝型油菜 × 白菜型油菜)> F1 ( 白菜型油菜 × 甘蓝型油菜 ) > 白菜型油菜,自交亲 和指数分别为 20.37、6.30、1.59、0.51,花粉活力表现为甘蓝型油菜 > 白菜型油菜 >F1(甘蓝型油菜 × 白菜型油菜)> F1 ( 白菜型油菜 × 甘蓝型油菜 )。
英文摘要:
      In order to research the affinity of Brassica rapa and B. napus in Tibet environment, the seed setting rate and affinity of B. rapa, B. napus and reciprocal cross combinations, the morphology, pollen vigor and self of hybrid F1 generation were studied. The results showed that the seed setting rate and affinity index of the crosses between B. rapa and B. napus were higher when B. napus cultivars was used as the female parent. The F1 hybrid of B. napus and B. rapa were self-compatible and their plant morphology was biased towards the female parent, The order of selfing affinity of the parents and the hybrids was as follows: B.napus > F1 (B. napus×B. rapa) > F1 (B. rapa×B. napus) > B. rapa, with the corresponding self-incompatibility index 20.37, 6.30, 1.59, and 0.51. The order of their pollen viability was as follows: B. napus> B. rapa> F1 (B. napus×B. rapa) > F1 (B. rapa×B. napus ).
