桃树QT01芽变枝的初步鉴定

通过离体芽接初步观察,结果表明:芽变枝(QT01)与艳红同株非芽变枝比较.QT01果实的形状、皮色、肉质、风味等性状无明显差异,而果实缝合线、果顶和成熟期差别明显,主要芽变性状是桃缝红凸如唇、果顶内凹似苹和晚熟10d;QT01母体枝与离体芽接株成熟果实的芽变性状表现稳定一致;成熟果实总糖、还原糖、总酸和Vc 4个指标营养成分含量均比艳红同株非芽变枝优良.QT01为桃树优异芽变新资源.利用价值较大.

Identification of Bud Mutation QT01 from Peach

Observation on budding in vitro of peach variety Yanhong indicates that there are no clear differences between bud mutation QT01 and its homophyletic non-mutation bud on shape, skin color, flesh texture and taste of fruit. A significant difference is the suture line, apex and maturity of fruit. Main characteristics of the bud mutation are red, convex and lip-like suture line, inter concave and apple-like apex, and 10 days late maturity.
