DrisStrawNinetyTwo Strawberry Plant Yield and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new strawberry plant varieties that are stable, high-yielding, and agronomically sound, as existing varieties may vary in quality, disease susceptibility, and adaptability.
Innovation Solution
The development of the strawberry plant variety 'DrisStrawNinetyTwo', resulting from a cross between proprietary strawberry plants '605U 84' and '629T178', which has been asexually propagated and tested for stability, fruit flavor, and specific growth characteristics such as open plant canopy and long fruit trusses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If new strawberry varieties are developed through cross-breeding, then fruit quality and yield are improved, but stability and true-to-type reproduction may be compromised
Solution Approach 1:
The patent performs preliminary selection and testing of progeny plants before formal variety establishment. Multiple plants were evaluated over several years (2013-2020) in controlled test plots to ensure stability and true-to-type reproduction before declaring the variety stable. This preliminary action ensures that only genetically consistent performers are selected for propagation.
Solution Approach 2:
The patent uses asexual propagation methods (runners and tissue culture) to create identical copies of the selected plant. This ensures that the genetic composition remains stable across generations, producing true-to-type reproductions that maintain the desired fruit quality and yield characteristics without genetic variation.
2Ease of manufacture
If strawberry plants are propagated via runners, then asexual propagation efficiency is improved, but genetic diversity and adaptability may be reduced
Solution Approach 1:
The patent employs runners for asexual propagation to create efficient, large-scale production of genetically identical plants. This method maintains the superior genetic composition of the selected parent while enabling rapid multiplication for commercial distribution.
Solution Approach 2:
The patent introduces tissue culture as an intermediary propagation method that bridges the gap between maintaining genetic stability and enabling adaptability. Tissue culture allows for the production of disease-free plants and can be combined with mutation breeding or genetic transformation techniques to introduce controlled genetic diversity while maintaining overall variety stability.
3Productivity
If strawberry varieties are selected for high yield, then productivity is improved, but disease susceptibility and abiotic stress resistance may worsen
Solution Approach 1:
The patent utilizes controlled stress conditions during the selection process, exposing progeny plants to pests and diseases to identify those with natural resistance. Plants that maintain high yield under stress conditions are selected, effectively converting the harmful factor of disease pressure into a beneficial selection criterion for developing resilient, high-yielding varieties.
Solution Approach 2:
The patent implements a feedback mechanism through multi-year field testing (2013-2020) where yield performance and disease resistance are continuously monitored. This feedback loop allows for the selection of plants that consistently perform well under various environmental conditions, ensuring that high-yielding varieties also possess adequate resistance to diseases and abiotic stresses.
