摘要: 野黄瓜Cucumis hystrix(2n=24)是在亚洲发现的第一个染色体基数为12的黄瓜属物种。这一发现对现行的以染色体基数和地理分布为基础的黄瓜属分类系统提出了质疑。采用SSR和RAPD两种分子标记对黄瓜属22份不同类型材料的亲缘关系进行了研究。结果表明,野黄瓜C.hystrix与黄瓜C.sativus var.sativus(2n=14)间的遗传距离(SSR:0.59,RAPD:0.57)小于其与甜瓜C.melo var.melo(2n=24)间的距离(SSR:0.87,RAPD:0.70)。SS

Abstract: Cucumis hystrix is the first wild Cucumis species possessing12basic chromosomes ever found in Asia.This discovery has posed a challenge to the current subgeneric division of this genus which was made mainly based on the differences in basic chromosome num
