为了探讨甘蓝型油菜育种材料的遗传效应,采用MINQUE(1)统计方法及AD模型对11个甘蓝型油菜育种材料及其杂种后代的产量性状和品质性状进行了遗传分析。结果表明,4个主要性状均存在极显著的加性效应和显性效应,其与环境的互作效应也达到了极显著水平,品质性状的遗传率明显高于单株产量的遗传率；4个性状的杂种F1和F2代平均优势表现较好,而超亲优势表现普遍较差；品质性状间存在较好的相关性,但其与单株产量的相关性较差；所有亲本主要性状的遗传效应差异明显,选用适合亲本可实现对特定目标性状的有效改良。%In order to study the genetic effects of agricultural traits of rapeseed breeding lines, inheritance analysis of the yield traits and quality traits for 11 elite rapeseed parents and their F1 were conducted using MINQUE(1) method and AD model. Four traits showed significant additive effects and dominant effects, and their interactions with environment were significant as well. The quality traits showed higher heritability than yield per plant. The F1 and F2 of the four traits exhibi-ted good mid-parent heterosis but poor better-parent heterosis. Correlations were found among the quality traits, not between quality traits and yield per plant. All 11 parents had a wide range of difference in genetic effect of main agricultural traits, which made it possible for them to be used for target trait-oriented improvement.
