| 摘 要： | 利用SSR、ISSR标记分析了24份非AA型野生稻及4份AA型对照的遗传多样性。结果表明,11对SSR引物共检测到104个多态性片段,平均每个引物扩增多态性片段9.5个。非AA型野生稻的特异性片段74个,占总片段数的71.2%;8个ISSR引物共检测到166个多态性片段,平均每个引物扩增多态性片段20.8个。非AA型野生稻的特异性片段113个,占总片段数的68.7%。两种标记构建的亲缘关系树基本相似。非AA型野生稻遗传多样性丰富,且具有很多独特的性状,可以为水稻育种提供丰富的种质资源。 |

| Abstract: | Genetic diversity in non-AA wild rice was studied using SSR and ISSR molecular markers.11 SSR primers generated total 104 polymorphic bands,average 9.5 bands per primer.74 of those polymorphic bands originated from the non-AA wild rice,account for 71.2%.166 polymorphic bands were detected with 8 ISSR primer pairs,average 20.8 bands per primer.113 of those polymorphic bands originated from the non-AA wild rice,account for 68.7%.Cluster dia-grams based on SSR data was very similar to that of based on ISSR data.The results showed that non-AA wild rice could provide rice germplasm resources in rich breeding for their genetic diversity and abundant unique characters. |
