Abstract:Abstract:【Objective】This research aim to enhance the utilization and research of wild apple germplasm resources, and promote the research of the wild apple.【Method】We used 129 single-plant of Xinjiang wild apple resources, collected in recent three years, as material to analyze genetic diversity and correlation of 12 quantitative traits(single fruit weight, fruit diameter, leaf size, etc. ) and 5 qualitative traits(leaf color, leaf opex type, leaf margin, etc.).【Result】The results showed that: qualitative traits such as leaf color, leaf opex, leaf margin, leaf shape and leaf surface had relatively concentrated distribution of frequency; Quantitative traits for example , single fruit weight, fruit diameters, petiole length , leaf blade width, soluble solid, trunk perimeter and tree heights had a large variation range, variable coefficients range from 16% to 51%. Diversity index of each traits were also larger, with mean value of 1.9264, minimum in leaf length (1.7359); maximum in fruit stem( 2.0525).【Conclusion】Xinjiang wild apple resources are abundant in genetic diversity, large diversity index and variation ranges are particularly reflected爄n fruit related characters. These indicate that abundant genetic diversity is an important characteristic of Xinjiang wild apple resources.
