| 摘要 | [Objectives] To distinguish loquat flesh color, thereby guiding early-age selection in loquat hybrid progeny. [Methods] Molecular markers based on the phytoene synthase gene (PSY) of loquat were applied to a hybrid progeny population derived from a cross between ‘Zaozhong 6’ and a local wild white-fleshed loquat resource ‘DB1’. [Results] Among the 49 hybrid progeny, 24 were identified as white-fleshed loquat resources and 25 as yellow-fleshed loquat resources. [Conclusions] The molecular marker of the PSY gene can effectively distinguish loquat flesh color and is of significant importance for guiding early-age selection in loquat hybrid breeding. |
