| 摘 要： | 对四川盆地宜栽的三系和两系甘蓝型杂交油菜(Brassica napus L.)的产量构成因素及其与单株产量的相关性进行了分析和比较。结果表明,单株有效角果数、每角粒数对单株产量在两类材料中均呈极显著正相关,但贡献大小在两类材料中不同;在三系中,每角粒数>单株有效角果数>千粒重;在两系中,单株有效角果数>每角粒数>千粒重。千粒重对单株产量在三系中呈负相关,但不显著,在两系中呈显著正相关。

| Abstract: | Correlation analysis and path analysis was conducted to study the yield components and their relationship with yield of three line and two line Brassica napus L.able to be cultivated in Sichuan Basin.As a result,significant positive correlation was revealed between effective pod number per plant and yield per plant,seed number per pod and yield per plant in both two materials with different contribution size.The order of contribution size in three-line rape was seed number per pod> effective pod number per ... |
