The average height of the 4 years old tree is 2.56 m，and the yield can reach 27 000 kg ? hm-2. The yield can be maintained at 45 000–52 500 kg ? hm-2 in high yield year. The average fruit weight is 221.9 g，the hardness is 8.67 kg ? cm-2，and the soluble solids content is 14.5%–16.5%，which is suitable for application in the south-central part of Hebei Province or in similar climate areas.
