Abstract: ‘Jizhen 2’is a new apple dwarfing rootstock cultivar selected from the seedling progenies of‘SH40’. It had a good grafting affinity. Grafted on‘Jizhen 2’as inter-rootstock,the Fuji tree will start flowering in the next year. The flowering and fruiting rate of the 3-year-old tree can reach 90%. The average yield of the 4-year-old tree can reach 15 000 kg ? hm-2. The height of the adult tree is about 85% of the SH40,the branching is 75%–85% of the SH40,and the middle and short branches account for more than 75% of the total branches. The yield can be maintained at 45 000–52 500 kg ? hm-2 in high yield year. The average fruit weight of the Fuji is 256.0 g. The hardness of the Fuji fruit is 8.7 kg ? cm-2. The soluble solids content is 14.5%–16.5%.‘Jizhen 2’is suitable for application in the south-central part of Hebei Province or in similar climate areas.
