摘　　要：采用土培方法，研究了甘蓝型油菜硼营养高效品种９１１８和低效品种９１４１间正反交杂种一代对缺硼的反应。结果表明，在土壤缺硼（土壤有效硼０．３０ｍｇ／ｋｇ）条件下，杂种一代硼效率系数平均为０．８８５，与高效亲本０．８９５相近，显著高于低效亲本０．１５４。缺硼时，杂交一代农艺性状的变化，硼的吸收，分配和运转系数均与高效亲本相一致。说明杂交一代硼的营养为高效，甘蓝型油菜硼营养高效性状为显性性状。The response of reciprocal F 1 generations crossed between Boron inefficient cultivar 9141 and Boron efficient cultivar 9118 of Brassica napus to Boron deficiency was tested under soil culture. The results obtained indicate that the mean of Boron efficient coefficient of the reciprocal F 1 generations is 0.885 when there is a Boron deficiency in soil, which is close to that of the Boron efficient cultivar (0.895), and is significantly higher than that of the Boron inefficient cultivar (0.154). When available Boron was deficient in soil, the variation of the agronomic traits and the uptake, distribution and translocation coefficient of Boron for the F 1 generations are consistent with that of the Boron efficient cultivar. It is concluded that the Boron utilization of the F 1 generations crossed from the two various Boron efficient parents is Boron efficient and the Boron efficient trait of Brassica napus is a dominant trait.
