摘要
为准确评价影响芝麻产量的主要农艺性状,对36份芝麻的8个农艺性状进行相关分析、灰色关联分析。结果表明,8个性状变异系数范围为6.13%~75.19%;单株蒴果数、果轴长、千粒重与单株产量呈极显著或显著正相关;灰色关联分析表明,与单株产量关联度较高(大于0.7)的性状有株高(0.720 6)、果轴长(0.740 0)、千粒重(0.704 4)、单株蒴果数(0.743 1),其排序为单株蒴果数>果轴长>株高>千粒重。因此,在今后芝麻选育过程中,应以结蒴多、果轴长、千粒重高作为主要的选育目标。
In order to accurately evaluate the main agronomic traits affecting sesame yield, correlation analysis and grey correlation analysis were carried out for 8 agronomic traits of 36 sesame cultivars. The results showed that the coefficient of variation of the eight characters ranged from 6.13% to 75.19%, and the capsule number per plant, fruit axis length and 1 000-seed weight per plant were significantly or significantly positively correlated with yield per plant. Grey correlation analysis showed that the traits with higher correlation degree(>0.7) were plant height(0.720 6), fruit axis length(0.740 0), 1 000-grain weight(0.704 4) and capsule number per plant(0.743 1), and the order was capsule number per plant>fruit axis length>plant height>1 000-grain weight. Therefore, the main breeding goals should be more capsular number, fruit axis length and 1 000-seed weight in the future breeding process of sesame.
