DrisStrawTwentyOne Strawberry Plant Breeding for Yield and Fruit Shape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strawberry varieties lack a combination of strong vigor, high yields, unique fruit characteristics, and improved fruit appearance, particularly in terms of size and shape, which are desirable for commercial cultivation and consumer preferences.
Innovation Solution
The development of the strawberry variety 'DrisStrawTwentyOne' through controlled crossing of proprietary parents '13H377' and '587L48', resulting in a plant with upright habit, dense foliage, large bi-conical fruit, and medium flesh, offering improved yield and appearance compared to its parents and commercial counterparts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional strawberry varieties are cultivated, then they can be grown commercially, but they lack a combination of strong vigor, high yields, and improved fruit appearance
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific phenotypic parameters including fruit shape (bi-conical), size (48.91mm length, 47.67mm width), color (dark red RHS 46A), and plant vigor characteristics. This systematic parameter selection and optimization resolves the contradiction by achieving both high productivity through vigor and reliable improved fruit appearance through controlled breeding parameters
2Volume of moving object
If strawberry varieties with larger fruit size are developed, then consumer preference is improved, but plant vigor and yield may be compromised
Solution Approach 1:
The patent applies composite materials principle through hybridization of two proprietary varieties ('13H377' female parent and '587L48' male parent), combining their genetic characteristics to produce offspring that exhibit both large fruit size (48.91mm × 47.67mm) and strong plant vigor. This genetic composite approach resolves the contradiction by integrating desirable traits from both parent varieties
3Shape
If strawberry varieties with unique growth habits are bred, then market differentiation is achieved, but adaptability to various cultivation conditions may be reduced
Solution Approach 1:
The patent applies local quality principle by developing a specific upright growth habit with dense foliage architecture that optimizes light interception and air circulation in commercial cultivation systems. The plant exhibits localized structural characteristics (upright habit, dense foliage, specific leaf arrangement) that enhance performance in targeted cultivation environments while maintaining adaptability through controlled breeding
