摘　　要：‘金圆’是以种间杂交品种‘金艳’(Actinidia chinensis×A. eriantha)为母本、中华猕猴桃(A. chinensis Planch.)为父本,从回交F1代群体中选育出的中熟黄肉猕猴桃新品种。通过对‘金圆’植物学性状、特异性、营养成分、贮藏性等进行研究,结果显示:‘金圆’果实为短圆形,单果重80～100 g,软熟时果肉橙黄色,质细味浓;‘金圆’的花瓣数和花丝数与母本‘金艳’接近,花冠直径和柱头数较‘金艳’分别增大了9.31%和52%,而花柄长度比‘金艳’短16.75%;萌芽率和果枝率略低于‘金艳’,但比‘海沃德’高出55.26%和43.33%;‘金圆’的可溶性固形物、总糖和可滴定酸含量与‘金艳’相当,但维生素C含量比‘金艳’高4.63%,是‘海沃德’的2.2倍;‘金圆’矿质元素含量丰富,P和K含量分别比‘金艳’高30.86%和22.53%,Mg含量比‘海沃德’高24. 86%;‘金圆’的总氨基酸含量丰富(8 mg/g),E/N和E/T值均高于‘金艳’和‘海沃德’,更接近于理想模式;‘金圆’在低温下(1～2℃,相对湿度90%～95%)贮藏150 d时,好果率在80%以上,200 d后,好果率仍有65%,贮藏性略低于‘金艳’,但显著高于‘海沃德’。利用Geo7-223分子标记扩增‘金圆’基因组得到3个条带,表明其与‘金艳’和‘金桃’在分子水平上具有一定差异。本研究表明‘金圆’具有良好的农艺性状和品质特性。‘Jinyuan’ is a kiwifruit cultivar bred in 2002 by backcrossing interspecific hybrid cultivar ‘Jinyan’( A. chinensis × A. eriantha ) as the female parent and Chinese kiwifruit ( A. chinensis ) as the male parent, which produced the medium-mature yellow fruit from the F 1 group. The botanical characters, specificity, nutrient composition, and storage ability of the ‘Jinyuan’ kiwifruit were studied in this paper. Results showed that the ‘Jinyuan’ fruit had a short columnar shape, with a weight of 80-100 g. The flesh of the soft ripening fruit was orange-yellow, and the number of petals and filaments were close to those of its female parent ‘Jinyan’. The corolla diameter and number of stigmas were 9. 31% and 52% higher than that of ‘Jinyan’, respectively. The length of the flower stalk was 16. 75% lower, and the germination and fruit branching rates were also slightly lower than that of ‘Jinyan’ but were 55. 26% and 43. 33% higher than the ‘Hayward’ variety, respectively. The contents of soluble solids, total sugar, and organic acids in ‘Jinyuan’ were similar to those of ‘Jinyan’, but vitamin C content was 4. 63% higher than ‘Jinyan’ and 2. 2 times higher than ‘Hayward’.‘Jinyuan’ exhibited mineral element richness, with P and K content 30. 86% and 22. 53% higher than that of ‘Jinyan’, respectively, and with Mg content 24. 86% higher than that of ‘Hayward’.‘Jinyuan’ also demonstrated abundant amino acid content (8 mg/g), and the E/N and E/T values were higher than those of ‘Jinyan’ and ‘Hayward’, close to the ideal model. After 150 d of storage in a harsh environment (T: 1℃-2℃, RH: 90%-95%), the good fruit rate was above 80%. After 200 d of storage, the good fruit rate was still 65%. The ‘Jinyuan’ storage property was slightly lower than that of ‘Jinyan’, but significantly higher than that of ‘Hayward’. Three bands were observed after amplification by Geo7-223, which were different from those of ‘Jinyan’ and ‘Jintao’ at th
