Abstract

Abstract: A new sweet cherry rootstock cultivar‘Jingchun 2’was derived from interspecific hybrids of sour cherry（Prunus cerasus）and Chinese cherry（P. pseudocerasus）. It is easy propagation and has very good grafting compatibility with most sweet cherry cultivars.‘Jingchun 2’could keep very slight injury and high survival rate under waterlogging stress，with prominent waterlogging tolerance than ‘Landing 3’，‘Jingchun 3’ and mahaleb（Cerasus mahaleb L.）. It has moderate dwarfing ability. The tree diameter of‘Rainier’/‘Jingchun 2’is 75.7% of‘Rainier’/‘Landing 3’in the 9th year after graft. The fully yields of grafting trees can be reached after planting 4–5 years. The average yield of ‘Rainier’/‘Jingchun 2’ was up to 21.8 kg per tree in the 6th leaf year.
