摘要： 本试验对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。研究结果表明，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，它们分别归为不同的品种类群，聚类分析将广西野生苦瓜确定为不同的亚种；栽培品种间差异小，很难进行类群的清晰划分。

Abstract: Abstract：Polyacrylamide gel electrophoresis(PAGE) of seed water-soluble protein, seed salt-soluble protein, seed alcohol-soluble protein and alkali-solube protein were 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 were conducted for the experiment data. The results showed that Guangxi wild bitter gourd was significantly different from other 13 cultivated cultivars in the protein fingerprints and quantitative genetic distances. However, The protein fingerprints showed a little differences among other 13 cultivars.Guangxi wild bitter gourd was regarded as a different subspecies from other 13 cultivars because of a larger genetic distance.All cultivars could not be clearly classified for the little difference.
