摘　　要：为了明确传统水稻品种和杂交稻长期混合间栽种植基因流是否会对传统水稻品种的种质产生影响,利用SSR分子标记对杂交籼稻冈优827,中优7号分别与黄壳糯按照8∶1混合间栽组合中基因流的发生情况进行了研究。结果显示,在两个组合的每个品种所检测的3 000个单株中均没有检测到基因流的发生。这一结果表明,现行的水稻品种多样性混合间栽模式中基因流不会对传统水稻品种产生影响。It＇s important to understand whether pollen-mediated gene flow has impact on rice landrace germplasm when inter-planting between rice hybrid and landrace for long-term in rice fields. In this study, the gene flow between hybrid indica rice varieties and Huangkenuo （a local traditional glutinous variety） in inter-planting fields with the ratio of eight to one （ eight rows of hybrid versus one row of Huangkenuo） were investigated using SSR molecular markers. The results indicated that the gene flow was not detected in two inter-planting combinations of 3 000 detected individuals in each variety. This finding indicated that rice varieties inter-planting model had no significant impact on rice landrace germplasm.
