摘要: 利用30对SRAP(Sequence related amplified polymorphism)引物和11对EST-SSR引物对西瓜9份栽培自交系、3份美国材料和6份非洲野生种进行了遗传多样性分析。结果表明,栽培种与野生种间多态性比率高达92.11%,野生种间多态性比率为34.11%,栽培种间多态性比率仅为21.05%。3份美国材料的扩增带多数与栽培种相似,但也扩增出了一些特异条带。试验表明SRAP和EST-SSR用于西瓜作物的遗传分析是高效可行的。

关键词: 野生西瓜, 栽培西瓜, 多态性, SRAP, EST-SSR

Abstract: The genetic diversities were studied using 30 SRAP primer pairs in 9 cultivated watermelon lines,3 American lines,6 African wild lines.The results implied that the polymorphic percentage between cultivated lines and wild lines was 92.11%, the polymorphic percentage in wild lines was 34.11%, and in cultivated lines was 21.05%.The bands of American lines were mostly the same as cultivated lines'and some specific bands were amplied.The results showed that SRAP and EST-SSR were highly effective and feasible on watermelon studying.

Key words: Wild watermelon, Cultivated watermelon, Polymorphic, SRAP, EST-SSR
