摘要:
采用形态学标记和SRAP分子标记相结合的方法,对100份不同来源的朝天椒(Capsicum annuum.L)材料进行了遗传多样性分析。结果表明:形态学标记分析中,11个农艺性状的的变异系数为 18.36%~34.99%,100份朝天椒材料在欧式距离14处聚为4个群组。在SRAP分析中,筛选出的8对引物,共检测到76条谱带,其中61条谱带呈多态性,多态性比率达80.3%,材料间相似系数变化范围为0.77至1.00,100份朝天椒材料在相似系数为0.815处分为2群组。SRAP聚类结果与品种的来源基本一致,表型聚类结果表现为生态环境相似、地理来源相邻地区的材料遗传关系较近。100份朝天椒材料遗传多样性丰富,聚类结果与传统形态学分类结果略有不同。
Abstract:
The genetic diversity of 100 kinds of Capsicum annuum.L from different countries and regions was analyzed based on the method of morphological marker combined with SRAP molecular marker. The results showed that the coefficient of variation of 11 agronomic traits ranged from 18.36% to 34.99%, and 100 pot pepper were clustered into four groups at the distance of 14. In the analysis of SRAP, eight pairs of primers were screened out, a total of 76 bands were detected and 61 bands were polynorphic. So, the polymorphism rate was 80.3%. The similarity coefficients of materials varied from 0.77 to 1.00. The materials were divided into two groups, when the similarity coefficient was 0.815. The results of SRAP clustering analysis were basucally consistent with the origin of the species. The results of phenotypic clustering showed that the genetic relationship among the materials with similar ecological enviroment and adjacent geographical location was close. The genetic diversity of 100 kinds of Capsicum annuum.L. was abundant, and there were differences between clustering results and traditional morphological classification results.
