Select Myrobalan tree ‘RI-1’

Abstract

A new and distinct variety of Myrobalan tree ( Prunus cerasifera ). Its novelty consists of the following unique combination of features that are desirable in a new interstock when growing cherries: 1. Decreasing the height of the cherry tree for more economical harvesting. 2. Providing earlier production of fuit when growing cherries with the new interstock variety on Citation Rootstock. 3. Increasing the number of rootstocks available for cherries. 4. Improving the opportunity to match soil type with the desired rootstock by using an interstock.

We claim:  
     
       1. A new and distinct variety of Myrobalan ( Prunus cerasifera ) tree, substantially as illustrated and described, characterized by being medium to large in size, moderately vigorous, upright growth and having graft compatibility with numerous rootstocks and also with various cherry trees, giving this Myrobalan tree the potential to be used as an interstock for growing cherries on various non-compatible rootstocks; the new variety is further characterized by having the ability to reduce the size of the cherry tree by shortening the length of the interstock between the cherry scion and the rootstock.
