摘　　要：‘翠玉’梨是以‘西子绿’为母本,‘翠冠’为父本杂交选育而成的早熟砂梨新品种。果实圆形,果形端正。果皮浅绿色,果面光洁具蜡质,基本无果锈,果点极小,萼片脱落,外观显著优于‘翠冠’。果肉白色,肉质细嫩,石细胞少,汁液多,口感脆甜,可溶性固形物含量11%左右,单果质量300 g左右。树姿较开张,花芽易形成,丰产性好。杭州地区3月底开花,花期比‘翠冠’迟2-3 d,7月上中旬成熟,果实生育期100 d左右,成熟期较‘翠冠’早7-10 d。S基因型为S3S4,可与‘翠冠’、‘玉冠’等互为授粉品种,但不能与‘初夏绿’相互授粉。Pear ＇Cuiyu＇,a new early maturing cultivar,was derived from the Pyrus pyrifolia cross ＇Xizilǜ＇×＇Cuiguan＇.The fruit is round and regular.Fruit skin is bright and clean with beautiful light-green color,has wax coat and no/less russet spot,dots are minimum-size.The flesh is white,crisp and juicy,sclereid content is lower,Brix value is about 11% in usual years,average fruit weight is about 300 g.The tree is open and easy to produce flower buds,which showed the character of high yield.It＇s flowering by the end of March（2 to 3 days later than ＇Cuiguan＇）,matures in early July in Hangzhou area（Zhejinag province,China）.The fruit development period is about 100 days（7 to 10 days earlier than ＇Cuiguan＇）.Its self-incompatible genotype is S3S4,which can be used as mutual pollination varieties among ＇Cuiguan＇,＇Yuguan＇,et al.,except ＇Chuxialǜ＇.
