| 摘 要： | 对6个食用向日葵品种（系）主要经济性状与产量的关联度分析结果表明：食用向日葵的盘粒数与产量关系最为密切,等权关联度和加权关联度分别为0.6934、0.6911;结实率与产量的关联度次之,分别为0.6256、0.6215;株高与产量的关联度居第3位;千粒重、盘径与产量的关系较远。因此选择食用向日葵品种时,要考虑品种综合农艺性状,避免用千粒重、盘径两项指标选择品种。

| Abstract: | Based on 6 edible sunflower varieties(lines) main economic traits and yield of the relationship between the correlation analysis,the results showed that edible sunflower disk grains most closely to its production,such as the right degree of correlation and the weighted correlation,0.693 4,0.691 1 respectively,seed rate and yield correlation times,0.625 6,0.621 5 respectively,plant height and yield correlation ranks No.3;grain weight,plate diameter and yield a more distant.Therefore,the purchase edible sunfl... |
