Cherry rootstock--Colt variety

Abstract

This invention relates to a new and distinct variety of cherry tree useful as a dwarfing cherry rootstock. The new variety originated as a seedling by crossing pollen from Prunus pseudocerasus Lind. onto flowers of Prunus avium L. F 299/2. Cherry trees on the understock of this variety are approximately 50 percent of the size of like cherry trees on F 12/1 understock. Also, this variety induces higher fruit bud production on the scion on this rootstock in the early life of the grafted cherry tree than if grafted on F 12/1 understock, thus giving heavier cherry crops earlier in the life of the grafted tree.

1.  A new and distinct variety of cherry tree useful as a dwarfing cherry rootstock substantially as illustrated and described, produced as a seedling by crossing pollen from Prunus pseudocerasus Lind. onto flowers of Prunus avium L. F 299/2, which when used as an understock induces less growth of the cherry tree, and higher fruit bud production on the scion in the early life of the grafted cherry tree.
