摘要

利用SSR分子标记技术对云南省嵩明和寻甸两地自然农田生态系统中合系41（现代水稻品种）和阿庐糯（传统水稻品种）混合间栽模式下品种间基因流的发生情况进行了研究。嵩明点，从阿庐糯到合系41的基因流频率为0.067%，从合系41到阿庐糯的基因流频率为0.033%；寻甸点，从阿庐糯到合系41、从合系41到阿庐糯的基因流频率均为0.033%。这一结果表明，品种间的基因流发生频率非常低，不会对保存种质资源本身的遗传特性造成明显的影响。

Abstract

In order to estimate the frequency of gene flow between varieties under cropland ecological conditions, a field experiment was conducted using Alunuo(a native traditional glutinous variety) and Hexi 41(a modern variety) as materials at Songming and Xundian sites in Yunnan Province, China. The frequency of gene flow was tested by means of SSR analysis. At Songming site, the frequency from Alunuo to Hexi 41 was 0.067%, from Hexi 41 to Alunuo was 0.033%. At Xundian site, both of them are 0.033%. The frequencies of gene flow are very low, indicating that interplanting model would not obviously affect the genetic characters of germplasm.

Key words： rice; gene flow; genetic diversity; germplasm
