摘　　要：对东营市及周边地区进行冬枣品种资源调查,从中选出5个冬枣优良单株,经对嫁接扩繁的各株系进行生物学特性、产量、果实品质等性状的观察测定,筛选出产量和品质最好的钰枣1号,脆熟期9月20日左右,比普通沾化冬枣早10 d,脆熟期可溶性固形物含量32.46%,明显优于目前栽植的沾化冬枣和其他4个冬枣优系,可作为良种进行区域试验和审定推广。Through the investigation on the variety resources of winter jujube in Dongying City and its surrounding areas,five excellent individual plants of winter jujube were selected and then grafted and propagated.By observation and determination of biological characteristics,yield and quality of each strain,Yuzao No.1 with the best yield and quality was screened.The mature period of Yuzao No.1 was 10 days earlier than that of ordinary winter jujube,and the soluble solids content at brittle maturity was up to 32.46%,which was obviously superior to currently planted winter jujube and the other four winter jujube strains.Yuzao No.1 could be used as a good variety for regional testing and validation promotion.
