摘　　要：韦端蜜红是从福建省古田县吉巷乡韦端村桃园中优选出的晚熟桃芽变新品种。具有晚熟、果大、肉脆、味甜、抗逆性较强等优良性状。果实近圆形,果顶微凸,果实缝合线浅且较明显,平均单果质量259 g;果皮底色黄绿色,果面带有深红色红晕;果肉黄白色,果汁多,风味甜,可食率达93.73%,成熟果实硬度为10.91 kg·cm^(-2)。果实汁液可溶性固形物含量(w,后同)12.6%~14.5%,总糖含量(以葡萄糖计)10.4%~11.0%,可滴定酸含量(以苹果酸计)0.15%~0.21%,抗坏血酸(维生素C)含量10.2 mg·100 g^(-1),果皮花青素、总酚、类黄酮含量分别为18.03 mg·kg^(-1)、1.65 mg·g^(-1)和1.53 mg·g^(-1)。在古田县3月上旬始花,果实成熟期为7月下旬至8月上旬,果实生长发育期约为135 d,在株行距5.02 m×5.03 m条件下,5年生树株产达92.41 kg。适宜在福建省桃主产区推广种植。Peach[Prunus persica(L.)Batsch.]is one of the deciduous fruit crops in Rosaceae originat-ed from China,which is popular in the world.China has the world’s largest yield of peaches,account-ing for approximately three-fifths of the world.Fujian province locates in a subtropical climate and on the west coast of the Taiwan Strait.Gutian county in Ningde city,situated in Fujian province’s east coastal area,is about 100 kilometers away from Fuzhou.Late-mature peach denotes a fruit development period of 121-150 days.Weiduanmihong is a late-mature peach germplasm resource budded from Yi-hong.The mutant of late-mature tree was found in 1994,which showed late-maturity,high quality,high yield,large and sweet fruit,strong stress resistance,richness in phenolic substances and stable excellent characteristics.Comprehensive analyses of ISSR(inter-simple sequence repeat)molecular markers showed that Weiduanmihong and Yihong could be differentiated at the similarity coefficient of 0.92 with UPGMA(unweighted pair-group method with arithmetic means)cluster analysis.And Weiduanmi-hong had different polymorphic bands from the Yihong.There are differences at the DNA level between Weiduanmihong and Yihong,showing that the Weiduanmihong is a bud-sport from Yihong.It has passed the professional certification by Fujian Forestry Bureau and it is called Weiduanmihong(S-SV PP-015-2021).Weiduanmihong has an open-center crown with light gray brown trunk.Leaf is long ob-ovatelanceolate with margin serrate.The flowers are rose-shaped with 5 petals.The optimum humidity at flowering stage is 67%-87%,and the most suitable temperature is 12-14℃.The fruit is near round with the apex slightly convex,and the suture line is obvious.The average weight of single fruit is 259 g.The ground color of the fruit is green-yellow with dark red color near the stone.The flesh is yellowwhite,hard and crispy and semi-cling stones.The edible rate of the juicy and sweet fruit is 93.73%,the flesh firmness is 10.91 kg·cm^(-2),and the total soluble solid content is
