一种与水稻抗稻瘟病基因Pi1紧密连锁的分子标记R112865-1及应用
摘要：
一种与水稻抗稻瘟病基因Pi1紧密连锁的分子标记R112865-1及应用。本发明属于分子生物学领域，涉及一种分子标记，具体的，涉及一种与水稻抗稻瘟病基因Pi1紧密连锁的分子标记，该分子标记含有Seq ID No.1所示序列。本发明还涉及扩增该分子标记的引物、该分子标记和引物在水稻抗稻瘟病基因Pi1定位或水稻遗传育种中的用途，以及一种水稻育种方法。本发明公开的与水稻抗稻瘟病基因Pi1紧密连锁的分子标记、扩增引物可以对水稻抗稻瘟病基因Pi1进行良好分型，可以用于水稻抗稻瘟病的分子标记辅助育种，为实现水稻抗稻瘟病性状的早期鉴定和筛选育种提供分子辅助技术支持，对于加快水稻品种的遗传选育和改良进程具有重要的理论和实践指导意义。
摘要（英）：

A rice blast disease resisting gene Pi1 tightly interlocked molecular marker R112865-1 and application thereof belongs to the field of molecular biology, relate to molecular markers, particularly to the rice blast disease resisting gene Pi1 tightly interlocked molecular marker R112865-1. The rice blast disease resisting gene Pi1 tightly interlocked molecular marker R112865-1 has a sequence shown as Seq ID No.1. The invention also relates to a primer for amplifying the rice blast disease resisting gene Pi1 tightly interlocked molecular marker R112865-1, application of the rice blast disease resisting gene Pi1 tightly interlocked molecular marker R112865-1 and the primer to rice blast disease resisting gene Pi1 positioning or rice genetic breeding, and a rice breeding method. The rice blastdisease resisting gene Pi1 tightly interlocked molecular marker R112865-1 and the amplification primer can well type rice blast disease resisting gene Pi1 and also can be applied to rice blast diseaseresistance molecular marker-assisted breeding to provide molecular assisted technical support for early determination and screening of rice blast disease resisting characters, thereby be of high significance in theories and practical guidance to acceleration of genetic breeding and improvement of rice varieties.
