摘　　要：以大名县枣育种园150个枣自然实生后代中分离出的酸枣实生群体为试材,调查了酸枣果实成熟期、裂果情况、果实鲜食品质等19个性状,并进行了相关性分析。结果表明:枣自然实生后代中的酸枣类型农艺性状变异很大,成熟期从8月上旬到10月上旬,单果重变异系数为0.45,双仁率变异系数为0.76;单果重与可食率、单核重与千仁重、出仁率与双仁率均呈极显著正相关;筛选出大果类型7个,抗裂类型7个,优质丰产类型6个,高出仁率类型6个,早熟类型5个。150 open pollinated Chinese juiube （Zizyphus jujuba Mill. ）progenies were investigated in breeding orchard in Daming county,and 19 main characters such as fruit maturity period,fruit cracking rate etc were recorded and analyzed. The results showed that there were much variation in agronomic characters, maturity was from early August to early October,the variation coefficient of single fruit weight was 0. 45, variation coefficient of dual rate was 0. 76. There were significant positive correlation between single fruit weight and the edible rate, the stone weight and the thousand weight, the rate and the double kernel rate. 7 big fruit types,7 cracking resistance types,6 high yield types,6 high rate of types and 5 early ripen types had been selected.
