利用２０个随机引物对厚皮甜瓜８个亲本与４个杂交种进行ＲＡＰＤ分析。１０个引物的扩增ＤＮＡ谱带具有多态性，亲本具有各自的特异谱带，绝大部分Ｆ１的扩增带型是双亲的互补带。各试材的相似系数范围为６３．６％－９６．５％。遗传距离聚类分析图表明，Ｆ１易与双亲或其一聚在一起。上述结果说明，可以利用ＲＡＰＤ标记在ＤＮＡ水平上进行厚皮甜瓜的亲缘关系及纯度的鉴定。 RAPD analysis was performed on 8 parents and 4 hybrids of Muskmelon melon using 20 random primers. The amplified DNA bands of 10 primers were polymorphic, their parents had their own specific bands, and most of the amplification bands of F1 were the complementary bands of parents. The similarity coefficient of each test material ranged from 63.6% to 96.5%. Genetic distance cluster analysis shows that F1 is easy to get together with their parents or their parents. The above results show that RAPD markers can be used to identify the genetic relationship and the purity of Muskmelon at the DNA level.
