摘　　要：【目的】选育鲜食枣新品种,丰富北京地区枣栽培种类。【方法】通过品种资源调查获得农家品种,采用多点区域试验,对植物学性状、果实品质、抗逆性、丰产性进行品质比较试验。【结果】选育出鲜食枣新品种‘鸡心脆枣’,果实鸡心形,平均单果质量13.2g,可食率98.1%。果皮薄,红色,光滑平整。果肉白色,多汁,酥脆细嫩,酸甜适口。可溶性固形物含量28%,总酸0.74%,维生素C 3.13mg/g。在北京地区9月中旬成熟。【结论】该品种自花结实,品质优良,早果性强,丰产稳产,抗病耐瘠,性状表现稳定,适于京郊宜枣平原及山地发展。[Objective]This research aims to select new fresh consuming jujube cultivar and enrich jujube cultivation species in Beijing. [Methods]Finding farmholding variety from investigation of germplasm., the botanical traits, fruit quality, stress resistance, fertile ca- pability were noted by multi point regional test.[Results]The new eultivar ＇Jixincuizao＇ has been selected. The fruits show heart-shape with smooth peel, red color and white flesh. The fruits also show good flavors and nice tastes. The average weight of the fruits was 13.2 gram and the edible ratio is 98. 1% ,the soluble solids content is 28 %,the total acid content is 0. 74%o ,and the vitamin C content is 3.13 mg/g. It ripens in mid-September in the Pinggu District of Beijing.[Conclusion]＇Jixincuizao~ is self-fruitful and has high yield, which is suitable for the cultivation in both plain and mountain area of Beijing.
