摘　　要：七月酥梨系1980年用幸水和早酥梨杂交育成。20多年来,在不同生态条件地区试种,结果表明:该品种性状稳定,具有结果早、品质优良、丰产性强、适应性广、极早熟等特点,其成熟期较日本主栽的早熟良种幸水、新世纪梨早1个月,较我国栽培较多的早酥梨早熟约20d。肉质倾向父本早酥梨细嫩而松脆、汁多;风味趋向母本幸水梨甘甜可口,具香味。Qiyuesu was derived from the cross between Kosui x Zaosu, made in 1980. Trials in different climatic areas over 20 years proved it is a very promising extra early cultivar. Its characteristics are stable. Trees are precocious and productive, highly adaptable to growing conditions. Fruits mature in early July in Henan province, a month earlier than that of Kosui (a leading cultivar widely planted in Japan) and Shinseiki, and 20 days earlier than Zaosu (one of the early season cultivars grown in China). The flesh is fine, juicy and crisp like its male parent-Zaosu. As it is sweet and delicious with aroma, the flavor tends to its female parent-Kosui. Due to its high eating quality it has been extremely planted in recent years in China.
