摘　　要：豫金蜜3号是以晚熟白肉鲜食桃品种秋蜜红为母本,通过天然杂交选育出的中熟黄肉桃新品种。该品种萌芽率高和成枝力均强,树势旺盛,半开张树姿。花蔷薇型,花粉多,结实力强。果实圆形,两半部较对称,果顶圆凸,缝合线浅。果实大,平均单果质量245 g。果面茸毛稀少,果皮底色浅黄;果肉黄色,硬溶质偏韧,核周围有红色素;果肉细嫩,风味浓甜,香味浓郁;可溶性固形物含量(w,后同)13.9%~16.2%,总糖含量8.2%~10.8%;黏核。在河南郑州地区,8月上旬成熟,果实发育期120 d左右。Peach(Prunus persica L.)is one of the most important fruit crops in the world,which is popular by consumers as the flesh is sweet and fruit is covered with excellent color.Yellow-fleshed fruit are rich in carotenoids,which have multiple physiological activities that are beneficial to human health,especially like antioxidation.Therefore,yellow flesh is one of the most important breeding goals in peach.There are many peach varieties in China but most of them are white fleshed,and only a few have yellow flesh.In recent years,yellow-fleshed peach cultivars have been obtained and they have attracted more and more consumers due to requirement of nutrition and health.Yujinmi 3(YJM3),a new yellowfleshed peach cultivar,was obtained from a natural cross of Qiumihong(QMH)with late-maturing and white-flesh,which was bred by Henan Agricultural University.Two hundred and ninety-six natural cross fruits were harvested in 2001,and then hybrid seeds were sown into a greenhouse.156 healthy seedlings were obtained in 2002.Hybrid peach trees began to flower and fruit in 2004,and among them,the fruit of Yunong 01-2-20-6 exhibited yellow flesh,hard melting and excellent flavor by the observation of three consecutive years.The Yunong 01-2-20-6 was selected as an excellent plant in 2006 for further trails.The bud wood of Yunong 01-2-20-6 was grafted onto the wild peach rootstocks(Amygdalus persica)and planted in three production areas(Zhengzhou,Nanyang and Xinyang city)in Henan province for variety comparison and regional trails.QMH and Huangjinmi 3(HJM3)were served as the control.All testing peach trees were planted by 3 m between trees and 5 m between rows under normal management conditions.After 5 years of observation(2014—2019),it was concluded that the characteristics of YJM3 were obviously different from the female parent QMH and HJM3.The full bloom date of YJM3 is early-April,similar with QMH and HJM3.The flowers of YJM3 are showy and have fertile pollen.The average ripening date of YJM3 is early August,about 120 d after full b
