简介：微卫星标记484/485和484/W2R被用来在米饭细菌原生质在Wx地点识别复等位基因。十五等位基因被使用微卫星班和G-T多型性在278accessions识别。在这些等位基因之中，(CT)_(12)-G,(CT)_(15)-G,(CT)_(16)-G,(CT)_(17)-G,(CT)_(18)-G并且(CT)_(21)-G没被报导。在Wx地点带不同等位基因的72根单个片断的替换线(SSSL)被使用Huajingxian74与开发(CT)是的_(11)-G等位基因作为施主在Wx地点包含12不同等位基因的一个接受者和20就职。代替的片断的估计的长度与17.4厘米的一般水准从2.2～77.3厘米。
