CIVH413 Strawberry Plant Breeding for Fruit Shape and Firmness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strawberry varieties face challenges in maintaining high productivity and disease tolerance, especially in high chill conditions, with limited shelf life and irregular fruit shape, size, and firmness.
Innovation Solution
The development of strawberry variety 'CIVH413' through controlled breeding, which results in a june-bearing strawberry with upright habit, conical and regular fruit shape, high firmness, and extended shelf life, adapted to high chill conditions and tolerant to common leaf and root diseases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional strawberry varieties are cultivated, then productivity may be maintained, but fruit shape regularity and firmness deteriorate
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific genetic traits that control fruit shape (conical form, regular contours) and firmness (resistance to softening). The variety CIVH413 exhibits these improved parameters through controlled variation of genetic and physiological parameters during the breeding process, achieving both regular fruit shape and maintained productivity.
2Duration of action of stationary object
If strawberry varieties with extended shelf life are developed, then fruit quality is maintained longer, but productivity during picking season may be reduced
Solution Approach 1:
The patent resolves this contradiction through parameter changes in the fruit's physiological characteristics. CIVH413 possesses altered parameters including higher firmness (measured as resistance to compression) and modified cellular structure that slows degradation. These parameter changes enable the fruit to maintain quality for 6-8 days post-harvest while the plant maintains high productivity throughout the picking season, as the traits are genetically fixed and do not compromise yield.
3Reliability
If strawberry plants are bred for disease tolerance, then reliability under adverse conditions improves, but fruit firmness and shelf life may deteriorate
Solution Approach 1:
The patent applies merging by combining multiple desirable traits into a single integrated variety. CIVH413 merges disease tolerance (resistance to common strawberry pathogens) with enhanced fruit firmness and extended shelf life through selective breeding. The genetic makeup integrates genes for pathogen resistance with genes controlling fruit texture and longevity, achieving synergistic effects where all traits coexist and reinforce each other rather than trade off against one another.
4Productivity
If conventional strawberry varieties are cultivated, then adaptability to various conditions may be maintained, but productivity consistency during picking season deteriorates
Solution Approach 1:
The patent applies parameter changes by optimizing specific physiological parameters that control productivity consistency. CIVH413 exhibits altered parameters including photosynthetic efficiency, resource allocation patterns, and fruit development timing that ensure steady production throughout the picking season. The variety maintains adaptability to high chill conditions and various soil types while achieving consistent daily yields, as the genetic parameters are tuned to provide stability without sacrificing environmental adaptability.

AI summary
This invention relates to a new and distinct variety of strawberry plant named ‘CIVH413’. The new June bearing strawberry variety named ‘CIVH413’ is primarily adapted to the climate and growing conditions of continental climate and is characterized by a rustic plant with upright habit and visible fruit easy to collect; the vigour is medium. The new strawberry has a high productivity, consistent during all the picking season; in particular is tolerant to the most common leaf and root diseases. The fruits have conical, attractive and very regular shape with orange-red colour; the size is big and consistent during all the time of picking. The firmness is high with a very good shelf life. The flavour is very good, balanced and aromatic.
