摘　　要：豫霜蜜是以晚熟鲜食桃品种秋蜜红为母本,通过实生选种育成的极晚熟鲜食桃新品种。果实圆形,顶端圆凸,缝合线深浅中等,两半部对称,果面茸毛稀少,果皮底色白,成熟时果面不着色;果肉白色,硬溶质,偏韧,黏核,风味浓甜;平均单果质量249.3g,最大单果质量480g。平均可溶性固形物含量(w,后同)16.1%,平均总糖含量14.5%,平均总酸含量0.26%,平均维生素C含量17.5 mg·100g^(-1)。该品种植株长势旺盛,树姿半开张;花蔷薇型,花粉多;果实发育期195d左右,在郑州地区10月中旬成熟;不裂果,商品性好,适宜河南各地区栽培,丰产性强。Peach(Prunus persica L.),originated in China,has been cultivated for a long time.The peach fruits are not suitable for storage and transportation due to the thin skin,soft and juicy flesh.The cultivation of complementary varieties with different maturity dates is necessary for extending market supply.Therefore,the breeding of different ripening complementary varieties are always the main focus of breeding.The extremely late-ripening peach with high sugar content and good flavor are expected by the consumers.Yushuangmi(YSM)is an extremely late ripening peach variety bred by Henan Agricul-tural University,YSM was derived from the seedlings of Qiumihong(QMH),a late-ripening variety.The seeds of QMH were collected in September of 2001 and sowed in March of 2002 with a planting space 0.5 m×1 m.These seedlings were transplanted to the breeding nursery in December of the same year with a planting space 3 m×4 m.The seedlings bore fruit in 2004.Based on the fruits characteris-tics observation of three consecutive years,a high-quality seedling recorded as Yunong 01-2-25-12 was selected in 2006.The regional field trials were conducted in Yuanyang,Xinzheng,and Ningling in 2013.QMH was used as control.The fruits of Yunong 01-2-25-12 showed better quality than QMH in different areas.The ripening date of it in Henan was 15 October,which was about 30 d later than QMH.Yunong 01-2-25-12 was renamed as Yushuangmi(YSM)and was granted new variety certification by the Variet Approval Committee of Henan province in 2019(S-SV-AP-006-2019).The fruits were round in shape,with a slightly convex on the fruit top.The depth and width of the sutures were medium.The flesh on both sides was symmetrical and uniformly ripe.The average fruit weight was 249.3 g,with the largest fruit weighing up to 480 g,bigger than that of QMH.The fruit surface had sparse fuzz,and the skin was yellowish-white.When fully ripe,the fruit surface did not change color.The flesh was white and had a firm texture.The average soluble solids and total sugars content were 1
