摘要: 以大久保桃自交后代为研究材料,对果实成熟期QTL进行了SSR标记。通过集群分离分析法(BSA)对分布于桃基因组上的165对SSR引物进行筛选,确认第4连锁群上的‘BPPCT015’标记与果实成熟期QTL有连锁关系。该标记在果实发育期 < 75 d和果实发育期 > 120 d的单株中所扩增出的带型与其表现型的符合度分别达到90%和92%,在88个不同成熟期的品种资源中的符合度分别为82%和84%。在桃育种实践中‘BPPCT015’标记可用于对成熟期的预先选择。

Abstract: The self-crossed progeny of Okubo peach were used as material to mapping the maturity QTL in peach. 165 SSR markers from the genome of Prunus persica were screened by Bulked Segregant Analysis(BSA). BPPCT015,a SSR on the 4th linkage group,was found link to the maturity QTL in peach. The conformity percentage(compared amplification band with phenotype)was 90% and 92% in early maturity(Fruit development period < 75 d)and late maturity(Fruit development period > 120 d)individuals respectively;In 88 peach accessions with different maturity date the conformity percentage was 82% and 84% respectively.

Key words: peach, maturity date, SSR molecular markers, preliminary selection
