基因(座)名称稻瘟病抗性基因
Pyricularia oryzae resistance-1
基因符号Pi1
所在染色体11 (已克隆)
供体材料LAC23

源自利比亚粳型品种"LAC23"的稻瘟病抗性基因,对稻瘟病菌IK81-3, PO6-6等有较强的叶瘟抗性;与Pi-k 连锁,重组值6.1%。

Yu等把Pi-1 定位于水稻第11 染色体的长臂末端,与RFLP 标记RZ536 的距离为11 cM;Mew等将其定位于RZ536 与NPB181 之间,距离分别为7. 9 和3. 5 cM;刘士平等利用同交育种中产生的回交群体,将Pi-1 定位在RFLP 标记RZ536 与SSR 标记RM144 之间,图距分别为9.7cM和6.8 cM;陈志伟等将Pi-1 进一步定位在SSR 标记MGR4766 附近,距离仅1.3cM。
