摘　　要：为选育出大别山山核桃(Carya dabieshanensis)优良无性系,对初选优树的果实性状鲜果重、果纵径、果横径、果皮厚度、鲜子重、子纵径、子横径和干仁重进行了分析。结果表明,优树果实性状间变异系数存在极显著差异,鲜果重变异系数最大为20.17%,子横径和子纵径变异系数较小,分别为5.78%和7.00%,优树间果实性状总体变异差异不显著;优树JZH、ZZ1和DZY具有果大优良特性,纵径为37.26~41.69mm,横径为34.29~44.19mm;优树ZW3具有皮薄优良特性,皮厚仅为4.18mm。In order to select and breed superior clone of Carya dabieshanensis,the fresh fruit weight,vertical and horizontal diameter of fruit,pericarp thickness,fresh seed weight,vertical and horizontal diameter of seed and dry kernel weight on fruit of primary selected plus trees were analyzed.The results showed that the difference were very significant among selected plus trees,CV of the fresh fruit weight was 20.17%,which was the biggest,CV of the horizontal and vertical diameter of seed were 5.78%and 7.00%,which were the smaller,the total heteromorphosis was not significant among selected plus trees.JZH、ZZ1 and DZY have large fruit character,the vertical diameter of which was 37.26~41.69 mm,the horizontal diameter was 34.29~44.19 mm.ZW3 has thin peel character,which was only 4.18 mm.
