果树农艺性状基因的分子标记及其应用

Molecular Markers and Its Application of Agronomic Trait Gene on Fruit Trees

总结了果树农艺性状基因标记策略和已获得的分子标记及其在果树上的应用。集团混合分离分析法(BSA)、平行芽变分析法(PSA)和已知信息捕捉法(KIH)是果树农艺性状基因标记筛选的主要方法。目前已获得了大量果树农艺性状基因的分子标记,这些标记是果树基因作图、图位克隆、分子辅助选择和种质资源鉴定等遗传研究与育种实践的有用工具。

In this paper the strategy of screening molecular m arkers of agronomic trait gene of fruit trees is summarized.Three main methods of screening molecular markers on fruit trees are Bulk Segregant Analysis(BSA ),Parallel Sports Analy-sis(PSA),and Known Information Hunting(KIH).A l ot of molecular markers of agronomic trait gene on fruit trees have been screene d.They are more useful for gene locus linkage mapping,gene-based cloning mar ker-assisted selection(MAS),and germplasm identification in fruit breeding.
