DrisRaspTen Raspberry Plant Multicolored Fruit and Low Shoot Emergence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new, stable, high-yielding, and agronomically sound raspberry plant varieties that offer improved characteristics such as multicolored fruit, reduced young shoots, increased anthocyanin pigmentation, larger fruit size, higher firmness, and vigorous growth.
Innovation Solution
The development of the 'DrisRaspTen' raspberry plant variety, resulting from a controlled pollination cross between 'Driscoll Estrella' and 'Driscoll Maravilla', which exhibits multicolored fruit, low cane emergence, and improved propagation through tissue culture, showcasing characteristics like large fruit size, high firmness, and vigorous growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional raspberry varieties are grown, then they produce uniform colored fruit, but they lack the multicolored phenotype and aesthetic appeal
Solution Approach 1:
The patent applies local quality by creating fruit with spatially varying color properties - red coloration concentrated at the base of the style and yellow coloration prominent away from the style. This non-uniform color distribution creates the multicolored phenotype that distinguishes the invention from traditional uniform-colored raspberry varieties.
2Productivity
If raspberries are allowed to spread vigorously through underground shoots, then they produce high yield, but they become invasive and difficult to manage
Solution Approach 1:
The patent converts the typically harmful invasive spread into a beneficial characteristic by selecting and propagating plants that exhibit vigorous growth and high productivity through underground shoots, while managing the spread to prevent it from becoming problematic. The variety maintains productive spreading behavior without the negative consequences of uncontrolled invasion.
3Quantity of substance
If high cane emergence occurs, then more shoots are produced for propagation, but tissue culture propagation becomes more difficult and less stable
Solution Approach 1:
The patent applies parameter changes by selecting for a specific quantitative trait - low cane emergence - that optimizes the propagation process. This parameter change from high to low shoot emergence creates more stable and reliable tissue culture propagation, demonstrating how modifying a numerical parameter can improve process reliability.
4Shape
If new raspberry varieties are developed through breeding, then improved characteristics are achieved, but stability and true-to-type reproduction may be compromised
Solution Approach 1:
The patent applies preliminary action by conducting extensive preliminary testing and evaluation of the new variety across multiple generations and locations before release. The variety underwent six years of testing in Santa Cruz County and was asexually propagated over several generations through tissue culture multiplication to ensure stability and true-to-type reproduction, preventing future variability issues.
