Strawberry Plant PE-7.2059 Conical Fruit Shape and Climate Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new strawberry variety that is well-suited to the climate and growing conditions of the central coast of California, with specific traits such as large fruit size, conical shape, and moderate disease resistance, which are not adequately met by existing varieties.
Innovation Solution
The development of the strawberry variety 'PE-7.2059', which is a result of a controlled cross between 'PS-7625' and 'VALOR', exhibiting unique characteristics like large red fruit, medium plant size, and strong interveinal blistering, adapted to the central coast climate and demonstrating stability through asexual reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing strawberry varieties are used, then general adaptability is maintained, but large fruit size with conical shape and specific quality traits cannot be achieved
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific fruit characteristics including conical shape, large size (22.5 grams average), and red coloration. The variety 'PE-7.2059' was developed through controlled crossing and selection to achieve these specific parameter values while maintaining adaptability to central coast California conditions through multiple years of field testing.
2Reliability
If disease resistance is improved, then reliability under varying conditions increases, but fruit quality and flavor may be compromised
Solution Approach 1:
The patent merges multiple desirable traits from parent varieties through controlled crossing. The resulting variety 'PE-7.2059' combines moderate disease resistance (angular leaf spot resistance) with good fruit quality characteristics including flavor, large size, and conical shape, achieving a balance where neither trait compromises the other.
3Quantity of substance
If fruit size is increased, then yield per fruit increases, but plant size and vigor may be affected
Solution Approach 1:
The patent applies local quality by concentrating genetic resources into producing large individual fruits (22.5 grams average) while maintaining medium overall plant size. The variety achieves this through specific genetic combinations that direct energy and resources preferentially to fruit development rather than excessive vegetative growth, resulting in large fruit on medium-sized plants.

AI summary
This invention relates to a new and distinct variety of strawberry plant named ‘PE-7.2059’. This new strawberry plant named ‘PE-7.2059’ is primarily adapted to the growing conditions of the central coast of California, and is primarily characterized by its large fruit size that is red in color, conical in shape with medium to strong gloss and a calyx that tends to be raised; seeds that range from level with to above the surface; medium plant size, with foliage that lacks gloss and has medium to strong interveinal blistering; fruiting truss pubescence that is strong and held strongly outward; and stolons, stipules and fruiting trusses that all lack anthocyanin coloration.
