众所周知,寻找与水稻的重要农艺性状紧密连锁的分子标记,并研究这些基因在染色体上的位置,是水稻遗传研究的重要内容,也是分子标记辅助选择(marker assisted selection,MAS)和根据作图位点进行基因克隆(map-based cloning)的基础。近年来,有关水稻育性基因、抗性基因及产量性状基因的定位、作图与分子标记研究取得了一定的进展,为开展 MAS 育种奠定了基础。1 育性相关基因的分子标记禾谷类作物的种子既是产品,又是繁殖材
It is well-known that finding molecular markers closely linked to important agronomic traits of rice and studying their location on the chromosomes are important elements of rice genetic research, as well as marker assisted selection (MAS) Point for the basis of gene cloning (map-based cloning). In recent years, some progresses have been made in the research on the mapping, mapping and molecular marker of fertility genes, resistance genes and yield traits in rice, which laid the foundation for MAS breeding. 1 Molecular Marker of Fertility Related Genes The seed of cereal crops is both a product and a propagating material
