| 摘 要： | 对芝麻9个品种9个数量性状与产量灰色关联度分析结果表明,产量与各产量性状的关联度大小顺序为:单株蒴果数》每蒴粒数>千粒重>始蒴高度>株高>全生育期>分枝数>空稍高度。芝麻产量主要取决于与其关联度较高的单株蒴果数、每蒴粒数、千粒重等性状。

| Abstract: | The gray relational grade degree between nine quantity characters and yield of nine sesame varieties were analyzed in this paper. The results show that the relational grade are as follows: capsules per plant > seeds per capsule > 1 000-seed weight > height of first capsule located > plant height > growth days > branch numbers > length of unfertile tip. This indicates that sesame yield mainly depends on capsules per plant, seeds per capsule, 1 000-seed weight and height of first capsule located, which provides scientific basis for the sesame selection of high yield and quality. |
