摘要：为探讨产区间冬枣的品质、遗传差异，将来源于河北和山东不同产地的冬枣按照完全随机区组设计栽种于河北、山东、北京的4个试验园，采取同样的栽培管理措施。通过对试验园冬枣果实的形态、品质等各项指标进行连年的分析测定和感官评价，并进行了DNA—AFLP分子标记研究。结果表明：河北、山东两省冬枣的单果质量、纵横径、果形指数、可食率、含水率、着色指数，果实Vc、总糖、可滴定酸和可溶性固形物含量等指标间没有明显差异，在同一试验园两省冬枣的感官评价差异也不明显；AFLP分析证明两省冬枣样品间遗传相似性很高（SM=0．9873～1．0000），被聚为一类，表明产自河北、山东的冬枣属于同一品种，造成冬枣果实品质差异的主要原因是立地条件和管理措施。冬枣品种内确实存在一定差异，这些差异属于单株变异，与产地来源无关。
＇ Dongzao＇ （ Ziziphus jujuba Mill. cv. Dongzao） is one of the famous fresh-eating cuhivars of Chinese jujubes that matures in middle October. ＇Dongzao＇ originates in the neighbouring region of Bohai Bay region. There is a little bit difference in the quality of ＇ Dongzao＇ fruit from different production area of Hebei and Shandong province, and we are curious about the reason. Four paralleled orchards, located respectively in Huanghua and Cangxian counties in Hebei province, Zhanhua county in Shandong province and Changping county in Beijing were established to evaluate the fruit quality of ＇Dongzao＇, in order to analyze the main factor causing the quality difference. The three-year-old grafted jujube trees derived from five different original provenances, which were Huanghua and Cangxian counties in Hebei province, and Zhanhua, Qingyun and Laoling counties in Shandong province respectively, were selected as test tree materials. The results are as follows： the quality traits of ＇ Dongzao＇ fruit such as weight, shape, water content, edible ratio, color of the pericarp, contents of Vc, organic acid, sugar, soluble solid content and the score of sense evaluation, as well as the AFLP markers, from different original provenances＇ tree materials, had not significant difference in the same experiment orchard. So we could consider that ＇ Dongzao＇ , native to Hebei or Shandong province, belonging to the same variety, which had a very small distance of heredity （ SM = 0. 987 3-1. 000 0 ）. The reason causing the difference of the fruit quality of ＇ Dongzao＇ in different orchards could be attributed to the different growth condition and cultivating methods. So the improvement of ＇ Dongzao＇ was mainly dependent on selecting of the individual advanced trees.
