Florida Elyana Strawberry Breeding for Disease Resistance and Fruit Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strawberry varieties in west central Florida face challenges with fruit deformation, seedy appearance, and susceptibility to crown and fruit rots, lacking consistent production of large, firm, and flavorful fruit over a long harvest period.
Innovation Solution
The development of the 'Florida Elyana' strawberry variety, which is a result of controlled hybridization between FL 96-114 and FL 95-200, exhibits improved fruit characteristics such as larger, firmer, and more flavorful fruit, with resistance to crown and fruit rots, achieved through asexual propagation and selection for desirable traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing strawberry varieties are grown in west central Florida, then fruit production occurs, but the fruit exhibits deformation, seedy appearance, and susceptibility to crown and fruit rots
Solution Approach 1:
The patent applies parameter changes by developing a new strawberry variety with altered genetic parameters that simultaneously improve disease resistance and fruit quality. The 'Florida Elyana' variety was bred to have modified physiological and morphological parameters including enhanced immune response to pathogens and improved fruit development characteristics that prevent deformation and seedy appearance
Solution Approach 2:
The patent employs composite materials principles through hybridization, combining genetic material from multiple parent strains to create a composite genotype. The 'Florida Elyana' variety resulted from crossing FL 96-114 and FL 95-200, merging desirable traits from both parents including disease resistance genes and fruit quality genes into a single composite variety
2Duration of action of moving object
If existing strawberry varieties are cultivated, then harvest occurs, but the harvest period is short and fruit consistency is poor
Solution Approach 1:
The patent uses parameter changes by modifying the phenological parameters of the strawberry plant through breeding. The 'Florida Elyana' variety was selected for extended fruiting duration and improved fruit set consistency, altering the temporal parameters of development to achieve both longer harvest periods and more uniform fruit production throughout the season
3Quantity of substance
If FL 96-114 is used as parent, then fruit production occurs, but the primary fruit are deformed
Solution Approach 1:
The patent applies the taking out principle by selectively extracting and eliminating the defective trait of fruit deformation from the FL 96-114 parent line through controlled crossing. The deformation defect was separated from the desirable high production trait by using FL 96-114 as one parent and FL 95-200 as the other, allowing selection of offspring that inherit production capacity without the deformation defect
4Quantity of substance
If FL 95-200 is used as parent, then fruit production occurs, but the fruit have a seedy appearance
Solution Approach 1:
The patent applies the taking out principle by removing the seedy appearance defect from the FL 95-200 parent line through hybridization and selection. The undesirable seedy trait was separated from the desirable production trait by crossing with FL 96-114 and selecting offspring that maintain high fruit set and production while exhibiting smooth fruit surfaces without excessive seed visibility

AI summary
A new and distinct variety of strawberry (Fragaria×ananassa), which originated from seed produced by a hand-pollinated cross between FL 96-114 and FL 95-200. The new strawberry, named ‘Florida Elyana’, is distinguished by production of large, firm, exceptionally flavored fruit and resistance to crown and fruit rots when grown in west central Florida or other areas that have a subtropical climate similar to that of west central Florida.
