HC2-1 Apple Tree Cross-Breeding for Early Maturity and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apple tree varieties lack desirable traits such as early maturity, attractive skin color, crisp flesh, balanced taste, and improved storage ability, which are not adequately addressed in current cultivars like 'DL33', 'HY46-3', and 'Gala'.
Innovation Solution
The 'HC2-1' apple tree variety, resulting from a controlled cross between 'DL33' and 'HY46-3', exhibits earlier maturity, shiny solid flush overcolor, finer flesh, and balanced taste, with characteristics distinct from both parents and 'Gala', including orange-red skin color, less greasiness, and enhanced storage life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing apple tree varieties are used, then current cultivars can be grown, but they lack early maturity, attractive skin color, crisp flesh, balanced taste, and improved storage ability
Solution Approach 1:
The patent combines desirable traits from multiple parent varieties through controlled cross-breeding. The new variety 'HC2-1' merges early maturity from one parent, attractive orange-red skin color from another, crisp flesh texture, balanced taste profile, and improved storage ability, creating a composite variety that exceeds the capabilities of any single parent variety.
2Volume of moving object
If fruit size is increased, then larger fruit is produced, but harvest maturity may be delayed
Solution Approach 1:
The patent achieves a breakthrough by changing the genetic parameters of the apple variety through controlled cross-breeding. The new variety 'HC2-1' simultaneously optimizes multiple parameters: fruit size (medium to large), harvest maturity (early, September), flesh texture (crisp), skin color (orange-red), and storage ability (4-5 months), breaking the traditional trade-off between fruit size and maturity timing.
3Shape
If skin color is made more attractive, then market appeal improves, but flesh quality may be compromised
Solution Approach 1:
The patent applies local quality by differentiating the characteristics of different parts of the fruit. The skin exhibits attractive orange-red coloration with solid flush overcolor for market appeal, while the flesh maintains superior crisp texture, fine grain, and balanced sweet-acid taste. This localized optimization of different fruit components resolves the contradiction between external appearance and internal quality.
