MAC 2137 Apple Tree Selective Propagation for Ripening and Flavor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new apple tree variety that offers a unique combination of smaller size, earlier ripening, crunchy texture, and sweeter flavor balance, while maintaining disease resistance and adaptability to different growing conditions.
Innovation Solution
The 'MAC 2137' apple tree variety, discovered through selective seed cultivation and asexual propagation, exhibits these characteristics, with fruit that is smaller than 'Honeycrisp' but similar to 'Minnewashta', and demonstrates moderate resistance to apple scab and cedar apple rust, with a distinct botanical description and growth habits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If larger apple varieties like 'Honeycrisp' are cultivated, then fruit size and yield are improved, but fruit texture becomes less crisp and flavor balance becomes less sweet
Solution Approach 1:
The patent changes the parameter of fruit size by selecting and propagating seedlings that naturally produce smaller fruits. The 'MAC 2137' variety is characterized by smaller fruit size (5.7 cm) compared to conventional varieties like 'Honeycrisp' (8.5 cm), while maintaining enhanced crispness and sweetness through controlled asexual propagation to preserve these parameter changes.
2Loss of time
If earlier ripening varieties are developed, then harvest time is improved, but fruit size and overall quality may be compromised
Solution Approach 1:
The patent achieves earlier ripening (August 28-September 20) by selecting seedlings with early-ripening genetics and propagating them asexually to maintain the trait. This parameter change in harvest time is achieved without significant compromise to fruit quality, as the smaller fruit size of 'MAC 2137' is compensated by enhanced flavor balance and texture.
3Reliability
If disease resistance is improved, then reliability is enhanced, but fruit quality and flavor may be compromised
Solution Approach 1:
The patent develops disease resistance through selective propagation of seedlings that exhibit resistance to apple scab and cedar apple rust. The 'MAC 2137' variety demonstrates moderate resistance to these diseases while maintaining high fruit quality with enhanced sweetness and crispness, achieving both reliability and flavor quality through careful genetic selection.
