Big Red Cherry Tree Dwarf Bush Cold Hardiness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of Prunus fruiticosa x Prunus cerasus cherry tree that exhibits desirable characteristics such as a spreading dwarf bush habit, bright red elongated heart-shaped fruit, high flesh to pit ratio, slight sweetness, and hardiness to extreme cold temperatures, which existing varieties do not adequately provide.
Innovation Solution
The 'Big Red' cherry tree is developed through a controlled cross between 'Egbert Center' and 'Kelleris 14', asexually propagated via softwood cuttings onto 'Carmine Jewel' rootstock, demonstrating a true-to-type reproduction and showing resistance to Cherry Leaf Spot and Black Cherry Aphids, with characteristics like bright red fruit, medium vigor, and hardiness to -40 degrees Celsius.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing cherry varieties are used, then they have established growth habits and fruit characteristics, but they do not provide the desired combination of spreading dwarf bush habit, bright red elongated heart-shaped fruit, high flesh to pit ratio, and extreme cold hardiness
Solution Approach 1:
The patent segments the breeding process into controlled cross-pollination between specific parental varieties ('Egbert Center' and 'Kelleris 14') to isolate and combine specific desirable traits. This systematic segmentation of breeding objectives allows for the development of a new variety with a unique combination of spreading dwarf bush habit, bright red elongated heart-shaped fruit, high flesh to pit ratio, and extreme cold hardiness that does not exist in existing varieties
2Adaptability or versatility
If a new variety is developed through controlled cross, then unique desirable characteristics can be achieved, but the breeding and propagation process becomes more complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination between selected parental varieties ('Egbert Center' and 'Kelleris 14') in advance to create the new variety. The asexual propagation method was established beforehand to ensure true-to-type reproduction, and virus-indexing was performed prior to budding onto rootstock. This preliminary preparation of breeding materials and propagation protocols streamlines the development process while achieving the desired unique trait combination
