PremA019 Apple Tree Breeding for Fruit Quality and Vigor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new apple tree variety that produces fruit with an attractive red skin color, appealing flavor, and large size, while maintaining high tree vigor and disease resistance.
Innovation Solution
The development of the apple tree variety 'PremA019', which was created through a controlled cross between 'Scifresh' and 'A174T01T204', resulting in fruit with a large size, attractive red skin color, and appealing flavor, and exhibiting high tree vigor and smooth to moderate bark texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a controlled cross breeding program is performed to develop new apple variety, then fruit quality (red skin color, flavor, size) is improved, but breeding time and complexity increase
Solution Approach 1:
The patent performs preliminary selection of parent varieties with desired traits ('Scifresh' for red skin color and 'A174T01T204' for large fruit size) before conducting the controlled cross. This preliminary action of selecting parents with complementary traits accelerates the breeding process by ensuring the desired characteristics are present in the first generation progeny, reducing the time needed for multiple generations of selection.
2Volume of moving object
If fruit size is increased to large size, then market appeal is improved, but tree vigor and disease resistance may be compromised
Solution Approach 1:
The patent applies local quality by selecting specific parent varieties that excel in different traits: 'Scifresh' provides disease resistance and red skin color, while 'A174T01T204' contributes large fruit size. The controlled cross combines these localized strengths in the progeny 'PremA019', which inherits both large fruit size (287g) and disease resistance, demonstrating that specific traits can be combined without compromising overall tree health.
3Shape
If smooth bark texture is maintained, then aesthetic quality is improved, but genetic diversity from rough-barked parents is reduced
Solution Approach 1:
The patent extracts the desired smooth bark texture trait from the 'Scifresh' parent variety while simultaneously extracting the large fruit size trait from the 'A174T01T204' parent. By taking out only the specific desirable traits through controlled crossing, the patent creates a new variety that combines smooth bark with large fruit size and disease resistance, rather than inheriting all traits including the unwanted rough scaly bark from one parent.
