苦瓜品种资源聚类分析

Cluster Anysis of Variety Resources in Bitter Gourd

对14个不同绿苦瓜、白苦瓜和广西野生苦瓜品种的种子可溶性蛋白、盐溶性蛋白、醇溶性蛋白和碱溶性蛋白进行聚丙烯酰胺凝胶电泳,运用遗传距离系数对14个苦瓜品种进行聚类分析方法;同时利用8个数量性状计算主成分遗传距离,对14个苦瓜品种进行聚类分析。结果表明,广西野生苦瓜与其他13个栽培品种之间遗传距离系数大,数量遗传距离也大,亲缘关系远,分别归为不同的品种类群;栽培品种间差异小,很难进行类群的清晰划分。

Polyacrylamide gel electrophoresis （PAGE） of seed water-soluble protein, salt-soluble protein, alcohol-soluble protein and alkali-solube protein was carried out by using 14 green, white and Guangxi wild cultivars in this experiment. At the same time, quantitative genetic distances were calculated by using 8 quantitative characters. Cluster anysis of 14 cultivars were conducted according to genetic distances. The results showed that Guangxi wild bitter gourd was significantly different from other 13 cultivated cuhivars in the protein fingerprints and quantitative genetic distances. However, the protein fingerprints showed a little difference among other 13 cuhivars. All cultivars could not be clearly classified for the little difference.
