DrisStrawThirtyTwo Strawberry Variety Fruit Quality and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new strawberry variety that exhibits desirable traits such as large, sweet, and juicy fruit with a conic shape and dark red color, which are not adequately met by existing commercial varieties like 'Sonata'.
Innovation Solution
The new strawberry variety 'DrisStrawThirtyTwo' (Fragaria×ananassa) is developed through asexual propagation via tissue culture and vegetative cuttings, combining the proprietary parents '89J167' and '283M 52', showcasing distinct characteristics including large conic fruits with a dark red color, medium firmness, and resistance to certain diseases like powdery mildew and Verticillium wilt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing commercial varieties like 'Sonata' are used, then cultivation is straightforward, but the fruit lacks desirable traits such as large size, sweet juicy flavor, and dark red color
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants with specific phenotypic parameters (large fruit size, conic shape, dark red color, sweet juicy flavor) through controlled asexual propagation via tissue culture and vegetative cuttings. This maintains the desirable traits while ensuring commercial viability.
Solution Approach 2:
The patent uses asexual propagation methods (tissue culture and vegetative cuttings) to create exact copies of the selected parent plant with its desirable characteristics. This ensures that the fruit quality traits are consistently replicated across multiple plants and harvest cycles without the variability introduced by sexual reproduction.
2Stability of the object's composition
If asexual propagation via tissue culture is used, then true-to-type propagation is achieved, but the process complexity increases
Solution Approach 1:
The patent employs tissue culture techniques to create exact genetic copies of the selected parent plant, ensuring true-to-type propagation. This method produces clones that faithfully replicate the desirable fruit characteristics without the variability of sexual reproduction.
Solution Approach 2:
The patent divides the propagation process into distinct stages: initial tissue culture multiplication to produce plantlets, followed by vegetative cutting propagation for final establishment. This segmentation allows each method to be optimized for its specific purpose while maintaining overall efficiency.
3Quantity of substance
If large fruit size is selected, then consumer appeal increases, but plant vigor and hardiness requirements increase
Solution Approach 1:
The patent carefully selects and propagates plants that achieve large fruit size parameters while maintaining balanced plant vigor and hardiness. The conic fruit shape and dark red coloration are also optimized parameters that correlate with quality while managing plant resource allocation.
