Abstract
A new and distinct cultivar of Prunus mahaleb is provided. The new cultivar is particularly well suited for serving as an understock during cherry production. A number of advantages are provided when compared to the standard Mahaleb rootstock. The cultivar is readily amenable to vegetative propagation (e.g., by the use of softwood cuttings), and exhibits improved resistance to Phytophthora spp. When used with a ‘Bing’ cherry scion, increased yields and yield efficiency have been observed without reduced fruit size. Improved precocity in bearing is displayed when compared to the standard Mahaleb rootstock. The new cultivar when grown without use as an understock forms a smaller tree than the ‘UCMH 55’ cultivar and the standard Mahaleb rootstock. Few suckers are produced.
Claims1
