| 摘 要： | 目的]全面评价不同类型芝麻品种中主要农艺性状对产量的效应。方法]选取国内外芝麻品种179份,按株型、叶腋花数、蒴果棱数差异进行品种分类,对各类型品种的主要农艺性状与单株产量分别进行相关和通径分析。结果]在各类芝麻品种中,单株蒴数对单株产量的相关系数和直接效应均为最大,其次是每蒴粒数和千粒重;蒴果长度对单株产量的作用主要是间接效应,株高在不同类型芝麻中表现有差异。结论]选育芝麻品种时要根据品种类型的不同,对不同性状应有所侧重。

| Abstract: | Objective] The research aimed to comprehensively evaluate the contributing effect of main agronomic characters to yield in different types of sesame cultivar.Method] Correlation and path analysis between agronomic characters and yield per plant were carried on in 179 sesame cultivars with different plant types,flowers per leaf axil,and locules per capsule.Result] The results showed that capsules per plant had the highest direct-effect on yield per plant,and the number of seeds per capsule and 1 000-seed weight came second.There were big differences in the height of plants and length of capsules between different types of sesame cultivars.Conclusion] Agronomic characters should be emphasized respectively in different types of sesame cultivar selections. |
