Day-Neutral Strawberry Cultivar for Uniform Large Fruit Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strawberry cultivars lack large, uniformly shaped fruit with high yields, low acidity, consistent cropping, and disease tolerance, along with desirable eating quality and floral flavor.
Innovation Solution
Development of the Fragaria x ananassa 'PGP182' cultivar, which is bred for large, glossy, juicy fruit with low acidity and distinct floral flavor, and exhibits strong vigor and day-neutral fruit bearing, combined with tolerance to Botryotinia cinerea and slight susceptibility to powdery mildew.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing strawberry cultivars are grown, then they produce fruit, but the fruit lacks consistent large size, uniform shape, and high yield
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific genetic traits that control fruit size, shape uniformity, and yield consistency. The cultivar 'PGP182' exhibits these improved parameters through controlled breeding between accessions GB96 and CC45, resulting in fruit that are consistently large (4.1cm x 4.2cm), uniformly reniform-shaped, and produce high yields (1,810g per plant), directly resolving the contradiction between manufacturing precision and productivity.
2Reliability
If existing strawberry cultivars are grown, then they produce fruit, but the fruit has high acidity and lacks distinct floral flavor
Solution Approach 1:
The patent changes the chemical composition parameters of the fruit by breeding for low acid content and high brix reading. The cultivar 'PGP182' achieves 0.53% total titratable acid (TTA) and 9° Brix, creating a reliable eating quality with distinct floral flavor that is consistent throughout the season, directly addressing the contradiction between reliability and harmful acidity.
3Reliability
If existing strawberry cultivars are grown, then they produce fruit, but they lack disease tolerance
Solution Approach 1:
The patent converts the harmful effect of disease susceptibility into benefit by selecting parent accessions with desirable disease tolerance traits. The resulting cultivar 'PGP182' exhibits tolerance to Botryotinia cinerea (grey mold), transforming the vulnerability to disease into a reliable disease-resistant characteristic that ensures consistent production.
4Duration of action of stationary object
If existing strawberry cultivars are grown, then they produce fruit, but the cropping is inconsistent throughout the season
Solution Approach 1:
The patent achieves continuous useful action through day-neutral fruit bearing, which allows the plant to flower and fruit continuously throughout the growing season without being restricted by photoperiod. The cultivar 'PGP182' produces consistent crops from May to October, eliminating cropping gaps and maintaining continuous production, directly resolving the contradiction between duration of action and time loss.
