摘　　要：甘梨2号是以四百目梨为母本、早酥为父本杂交育成的早熟梨新品种。果实近圆形,果皮黄绿色,平均单果质量255 g;果面光洁,果点中密、明显;果肉乳白色,肉质细、酥脆,石细胞少,汁液多,酸甜适口,具清香;果心小。可溶性固形物含量(w,后同)12.4%~13.1%,可溶性糖含量8.8%,可滴定酸含量0.24%,果肉维生素C含量5.4 mg·100g^(-1),品质优良。该品种树势中庸,萌芽力高,成枝力低,以短果枝结果为主,连续结果能力强。在甘肃景泰地区8月中旬成熟,货架期20 d,冷藏条件下可贮藏4个月。适宜在我国西北、华北等梨产区推广种植。Ganli 2 is a new early ripening and high quality pear cultivar bred from the cross of Shihyakume×Zaosu.The cross was set in 1981 and selected as the superior line in 1993.Comparison tests and production adaptability tests were carried out with Zaosu as the control from 2008 to 2015.The results showed that early fruit maturity,good quality,high yield and stable yield,strong resistance to adversity,wide adaptability,and excellent comprehensive traits.In 2016,it was recognized as the crop variety of Gansu province,and in 2018 it obtained the new plant variety right.In Baiyin area of Gansu Province,Ganli 2 blossoming in late April and ripening in mid-August.The fruit development days of Ganli 2 are about 110 days,and the fruit ripening period is about 10 days earlier than Zaosu.The fruit is nearly round with yellowish green rind,and the average weight of single fruit is 255 g.Fruit surface is smooth,fruit dot is dense and obvious;The flesh is milky white,the flesh is fine,crisp,the stone cells and the residue are little,the juice is much,the sweet and sour palatability,has the faint fragrance;The core is small.The content of soluble solids is 12.4%^(-1)3.1%,soluble sugar is 8.8%,titratable acid is0.24%,and vitamin C is 5.4 mg·100 g^(-1) of pulp.This kind of tree potential is moderate,germination force is high,into branch force is low,give priority to with short fruit branch result,continuous result ability is strong.The content of soluble solids is 12.4%^(-1)3.1%,soluble sugar is 8.8%,titratable acid is0.24%,and vitamin C is 5.4 mg·100 g^(-1) of pulp.The shelf life is 20 days.It can be stored for 3-4 months under cold storage.The tree potential of this product is moderate,the germination rate is high,the branch forming force is weak,the short fruit branch results mainly,has the axillary flower bud bearing habit,the continuous bearing ability is strong,the fruit-setting rate is high,the average 3 fruits per inflorescence.The yield was 1737.4 kg per 666.7 m2 in the fifth year,which was 7.1%higher than that of the co
