摘　　要：阐述并比较了基于遗传连锁图谱、利用集团分离分析或分离群体分组分析(BSA)以及全基因组关联分析(GWAS)等鉴定主要果树重要性状QTL的方法,综述了近年来果实外观品质和内在品质、生长发育、抗生物和非生物胁迫等重要性状的QTL鉴定的研究成果,对QTL鉴定及定位方法策略等问题进行了讨论与展望,以期为果树QTL鉴定研究以及果树育种提供参考与借鉴。The methods for QTL identification of important traits in fruit trees by genetic linkage map,BSA and GWAS are expounded and compared.The current review summarizes advancement on the identification of QTLs associated with important traits of fruit trees,including external appearance,internal quality,growth and development,resistance to biotic and abiotic stress,in recent years.The purpose of this review is to provide clues for understanding the QTL identification and breeding of fruit tree,and to discuss and propose the methods and strategies that can be used for QTL identification and mapping of important characters in fruit trees.
