Abstract: Ganli 2 is a new early ripening and high quality pear cultivar bred from the cross of Shihya- kume ×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 ad- versity, wide adaptability, and excellent comprehensive traits. In 2016, it was recognized as the crop va- riety 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%-13.1%, soluble sugar is 8.8%, titratable acid is 0.24% , 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%-13.1%, soluble sugar is 8.8%, titratable acid is 0.24%, 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 inflo- rescence. The yield was 1 737.4 kg per 666.7 m2 in the fifth year, which was 7.1% higher than that of the control variety Zaosu. In the cultivation, attention should be paid to the management of water and fertil- izer, so as to prevent the tree from becoming weak after a large amount of fruit in the full fruit period, which is suitable for spreading and planting in the pear producing areas in Northwest and North China.
