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。
Nineteen characters of jujube fruit jujube were isolated from 150 jujube progenies of Dazao County jujube seedlings. The fruit jujube fruit ripening period, fruit cracking and fresh fruit quality were investigated and their correlations were analyzed. The results showed that the jujube type agronomic characters varied greatly from early April to early October. The coefficient of variation of single fruit weight was 0.45 and the coefficient of variation of double kernel rate was 0.76. The fruit weight and edible rate, Single kernel weight and kernel weight, kernel rate and double kernel rate were significantly and positively correlated. Seven large fruit type, seven anti-splitting type, six high-quality and high yield type, six kernel type were selected, Five types of precocious.
