[Objectives] To study the germplasm resources of excellent peach cultivars. [Methods] Five peach cultivars were introduced, including ‘Jinxiu’ peach, ‘Jinxiang’ peach, ‘Chunxiao’ peach, ‘Hujingmilu’ peach and ‘018 nectarine’ peach. Then, these five cultivars were used to study the biological characteristics of peach trees, namely, as phenology, fruit quality, heat resistance, cold resistance and other resistance. [Results] Five cultivars of peach plants grew fast and robust, among which ‘018 nectarine’ had very crisp fruit, ‘Jinxiu’, ‘Jinxiang’, ‘Chunxiao’ and ‘Hujingmilu’ had very sweet fruit; the peach trees of these five cultivars have good water resistance, heat resistance and cold resistance. [Conclusions] The results of this study can not only provide a reference for the introduction of peach trees, but also provide a practical basis for the large-scale planting of peach trees.
