摘　　要：对104份光核桃种质资源幼树叶片的11个表型性状进行了多样性分析。结果表明,所有供试材料的8个描述型性状(叶色、秋叶色、叶形、叶尖形状、叶基形状、叶腺,叶缘形状、叶腺数量)多样性指数在0.191~1.641,3个数值型性状(叶长、叶宽,叶柄长)的变异系数范围为14%~31%。大部分种质资源在拉萨同质园内表现了出丰富的多样性。The objective of this research was to evaluate the diversity of Prunusmira Koehne germplasm resources by basic phenotypic characters.A total of 104 Prunusmira Koehne accessions were tested.Result showed that the genetic diversity 8 descriptive traits(leaf color,the autumn leaves color,phylliform,tip shape,leaf base shape,leaf gland,leaf shape,leaf number of gland)ranged from 0.191 to 1.641,in addition,the variation coefficients of 3 numerical characters(leaf length,blade width,Petiole length)ranged from 14%to 31%.Most germplasm resources showed rich diversity that,by taking use of these resources,might provide an insight for selecting parental materials in breeding for elite adlay.
