中文摘要：

采用SRAP分子标记手段,研究了10份不同果色、果形的辣椒种质的亲缘关系。结果表明：22个SRAP引物组合,共扩增出330个条带,多态性比率为52.88%。10份辣椒材料间的相异系数为0.205-0.5429,当遗传距离为0.3959时,可将上述种质分为3类。第一类包括6份种质,分别是9007、9024、8022、9006V1、HT、JO-Ⅰ。第二类共有3份种质,分别是9036Ⅰ、SS-Ⅰ、9049Ⅱ。第三类有1份种质,是7036,上述分类的结论与用果形进行区分的结果不完全相符。

英文摘要：

Using SRAP molecular method, relationship of 10 pepper germplasm of different fruit color and shape was studied. The results indicated that 22 primer combinations could amplified 330 bands with polymorphism rate of 52.88%. The dissimilarity coefficient of ten germplasm was from 0.205 to 0. 5429 ,when genetic distance was 0. 3959, germplasm above could be classified into 3 gourps, and the first group included 6 germplasm of 9007, 9024,8022,9006V1, HT, JO - Ⅰ ; the second group included 3 germplasm of 9036Ⅰ, SS - Ⅰ; 9049 Ⅱ and 7036 was belonging to the third group, while the classification results were not fully corresponding to the classification by fruit shape.
