选取油用向日葵资源80份,采用灰色关联分析方法,对影响向日葵产量(单株粒重)的主要农艺性状进行分析。结果表明:与单株粒重关系密切程度从大到小的顺序是:单株成粒数>单株总粒数>粒宽>花盘直径>结实率>百粒重>粒长>百仁重>茎粗>株高>皮壳率>长宽比。因此选择单株成粒数和总粒数较多、籽粒较宽的材料有利于得到产量较高的向日葵自交系,为选育高产油用向日葵品种提供了依据。
Eighty oilseed sunflower resources were selected and the main agronomic traits affecting sunflower yield (grain weight per plant) were analyzed by gray relational analysis. The results showed that the order of the relationship between grain weight per plant weight and grain weight was as follows: grain number per plant> total grain number per plant> grain width> disk diameter> seed setting rate> grain weight> grain length> > Stem diameter> height> husking rate> aspect ratio. Therefore, selecting the number of grains per plant and the total number of grains is more, and the material with wider grain size is advantageous to obtain the high-yielding sunflower inbred lines, which provides a basis for breeding sunflower varieties with high yield.
