Plared 15105 Strawberry Variety Breeding for Yield and Fruit Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a strawberry variety that combines desirable traits such as early flowering and ripening, large fruit size, and specific leaf and fruit characteristics, which are not adequately met by existing varieties like 'San Andreas'.
Innovation Solution
The development of the strawberry variety 'Plared 15105' through crossing two parent varieties and subsequent asexual propagation, which results in a semi-upright growth habit, medium width fruit band without achenes, raised calyx attachment, and conical shape with medium red color, along with early flowering and ripening, and improved yield and quality characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the strawberry variety has early flowering and ripening traits, then the productivity is improved, but the fruit size may be reduced
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific phenotypic parameters including early flowering time, fruit size (30-50g), conical shape, and raised calyx attachment. The breeding program optimized multiple parameters simultaneously to achieve both early productivity and adequate fruit size, resolving the contradiction between rapid maturation and fruit development.
2Manufacturing precision
If the fruit band without achenes is narrow, then the manufacturing precision is improved, but the quality and appearance may deteriorate
Solution Approach 1:
The patent specifies a medium-width band without achenes as an optimal parameter that balances manufacturing precision (uniform fruit shape) with quality (appeal and marketability). This medium width provides sufficient structural uniformity while maintaining adequate surface area for aesthetic quality and consumer acceptance.
3Ease of manufacture
If the calyx attachment position is level with surface, then the ease of manufacture is improved, but the fruit quality may deteriorate
Solution Approach 1:
The patent specifies raised calyx attachment as a key phenotypic parameter that improves fruit quality by providing better protection during development and enhanced appearance. The raised position maintains adequate harvesting ease while significantly improving marketability and consumer acceptance compared to level attachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The 'Plared 15105' variety exhibits enhanced yield and quality, with larger fruit size, earlier flowering and ripening, and maintains quality characteristics suitable for fresh consumption and processing, with improved adaptability and disease resistance.
Implementation Method 1
mother plants that had developed several stolons were subjected to a heat treatment, or thermotherapy, at 36° C.-37° C. for 3 to 4 weeks
