中文摘要:
      以四川盆地宜栽的10 个甘蓝型杂交油菜为材料,对不同甘蓝型杂交油菜枝、荚、粒结构特点及其与产 量的关系作了相关研究。结果表明院经济产量与枝、荚、粒均呈正相关;一次分枝重、二次分枝荚果数、二次分枝荚壳 重、二次分枝粒重、二次分枝数、二次分枝重、一次分枝粒重对产量的影响较显著,其中二次分枝数、二次分枝重、一 次分枝粒重对产量的影响达到极显著水平。因此,在高产育种时,在兼顾其余4 个因素和其他农艺性状的同时,应着 重加强对这3 因素的选择。
英文摘要:
      The paper studied the yield-related of different hybrid rapeseed branches, pods, grain structures, using 10 hybrid rapeseed as the material by correlation analysis. The results showed that economic production presented positive correlation with the branches, pods and grains. First branch weight, pod number of secondary branches, secondary branches pod shell weight, seed weight of secondary branches, number of secondary branches, weight of secondary branches and weight of first branch impacted more significantly on the yield, number of secondary branches, weight of secondary branches, first branches weight and yield-related characters reached significant level. So when we take four components and the other agronomic characters, the choice of these 3 factors could be considered to be utilized in high yield breeding.
