摘　　要：烟香玉是以引进中熟苹果品种红露为母本实生选育的黄色苹果新品种。该品种果实长圆柱形,平均单果质量120.2 g,果皮呈黄色,表面光滑,果肉呈浅黄色,口感硬脆,肉质细腻,风味甘甜,可溶性固形物含量(w,后同)为14.3%,去皮硬度9.2 kg·cm^(-2),可滴定酸含量0.32%,维生素C含量2.53 mg·100 g^(-1),较其他早熟品种耐贮藏,自然条件可贮藏2个月。在烟台地区成熟期一般在8月中下旬,抗病性较强,适宜在山东、山西、新疆、陕西等苹果适栽区进行免套袋栽培,盛果期产量29.4 t·hm^(-2)。Yanxiangyu is a new early-maturing and yellow apple variety, formerly named HL-65. It is the seedling offspring of the Korean-introduced variety Honglu. Healthy seedlings were planted in the spring of 2005. After evaluation and screening, HL-65 was selected as an excellent single plant. Scions were collected in 2011 and grafted on Begonia octagona as rootstock.

The fruit size of this variety is small, the average single fruit weight is 120.2 g, the fruit is long and cylindrical, the fruit surface is smooth, nonarris and waxy, and the fruit dots are medium large and medium dense. The variety has yellow peel,light yellow pulp, hard and crisp taste and sweet flavor, with soluble solid content of 14.3%, peeling hardness of 9.2 kg·cm^(-2), titratable acid content of 0.32% and vitamin C content of 2.53 mg·100 g^(-1). It was accepted by experts organized by Yantai Science and Technology Bureau in September 2016 and was named Yanxiangyu. Yanxiangyu is more resistant to storage than other early maturing varieties. It can be stored for 2 months under natural conditions. It matures in mid and late August. The fruit growth period is 115 days and the maturity degree is the same.
