以河南省银杏资源为对象，通过资料收集和实地调查，对河南银杏主产区10种优良银杏栽培品种的种核形态、种核性状、各性状之间的相关系数进行比较分析.对河南观赏银杏和古银杏进行实地踏查和资料整理分析.结果表明：河南优良栽培银杏品种的主要产量性状表现与国内主要栽培区的其他品种相比并不低；性状的变异系数和出仁率高于国内主要栽培区的品种.河南银杏观赏品种资源主要有塔形银杏、垂枝银杏、裂叶银杏、斑叶银杏、黄叶银杏、壮枝银杏、大叶银杏、柱冠银杏和异叶银杏等9种.河南省有古银杏5153株，其中新县和嵩县是河南银杏古树分布最为集中的区域，占全省总数的90%以上.在已知性别的银杏古树中，雌株占85%左右.树高最大为46.0 m，最小为7 m；树龄最长为2800年；胸径最大为3.8 m，最小仅为0.3 m；平均冠幅最大为40.0 m，最小为4.2 m .对河南银杏资源的特点分成进行良种栽培银杏、观赏银杏和古银杏3大类进行探讨.

Taking the ginkgo resource in Henan Province as the research object,through data collection and field survey,we comparatively analyzed the variation coefficient among the seed nucleus morphology ,seed nucleus characters,other characters of 10 excellent ginkgo cultivars in the main producing areas of Henan. Based on the field survey and data analysis of ginkgo and ancient ginkgo,the results show as follows. The main yield traits of good ginkgo cultivars in Henan is not worse than other ginkgo varieties in main planting areas of China. Moreover their variation coefficient of traits and kernel rate are higher than that of the main planting area of China. The ginkgo resources in Henan are mainly tower type,weeping ginkgo,crack leaves ginkgo,variegated leaves ginkgo,yellow leaves ginkgo,strong branches ginkgo,big leaves ginkgo,column crown ginkgo and variant leaves ginkgo. Henan Province has 5153 plants of ancient ginkgo,and Xinxian County and Songxian are the most concentrated area of ancient ginkgo trees in Henan,accounting for more than 90% of the total number. In gender,the female plants accounted for about 85%. The maximum tree height was 46 m,while the minimum was 7 m. The oldest tree was 2800 a. The maximum DBH was 3.8 m,while the minimum is only 0.3 m. The average width is 40 m,and the minimum was 4.2 m. The Henan ginkgo resource characteristics of three categories,which are benign planting ginkgo,ornamental ginkgo and ancient ginkgo,were discussed.
