Abstract

A new and distinct Prunus rootstock compatible with other Prunus varieties and producing trees with reduced growth, adaptability to soil and high productivity.

Description

Classification: Prunus L.
Varietal denomination: ‘Piku 3’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of hybrid Prunus known by the varietal name ‘Piku 3’. The new variety was discovered in 1972 in a selective breeding program designed to produce growth reducing rootstock for cherry trees in Dresden-Pillnitz, Germany as a cross between an unnamed, unpatented variety of Prunus pseudocerasus (female parent) and an unnamed, unpatented Prunus hybrid of Prunus canescens×Prunus incisa (male parent). The new variety differs from its parents in its growth habit. The following characteristic distinguish the new variety from Prunus avium rootstock varieties:
    • 1. Three-way hybrid.
    • 2. Reduces growth in grafted varieties by 20%.
    • 3. Minimally precocious crop.
    • 4. Adaptable to soil.
The new variety was first asexually reproduced via green cuttings in 1975 in Dresden-Pillnitz, Germany and subsequent propagation therein has confirmed that the characteristics of the new variety are stable and are transmitted to subsequent generations.
DESCRIPTION OF THE DRAWINGS
The accompanying photographic drawings illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type.
FIG. 1 shows the tree of the new variety;
FIG. 2 shows a branch with leaves;
FIG. 3 shows a branch with flower buds; and
FIG. 4 shows a branch with opened flowers.
 DESCRIPTION OF THE PLANT
The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions via green cuttings carried out in Dresden-Pillnitz, Germany. The color designations were taken outdoors in Dresden-Pillnitz, Germany. Rootstocks were 6 to 7 years old when described. Color designations are noted with reference to standard Prunus avium rootstock. The new variety is adaptable to soil and is free of PNRV and PDV. As a rootstock, it can be reproduced via softwood cuttings and tissue culture. The new variety anchors well with some root sprouts, has good compatibility with grafts and exhibits growth reduction.
