DrisRaspSix Raspberry Plant Breeding for Yield and Fruit Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new raspberry variety that combines high productivity, partial self-fruitfulness, and medium-sized, bright red berries, which are not adequately met by existing raspberry varieties.
Innovation Solution
The new raspberry variety 'DrisRaspSix' (Rubus idaeus L.) is developed through crossing 'Driscoll Maravilla' and 'Driscoll Francesca', exhibiting high productivity, partial self-fruitfulness, and medium-sized, bright red berries, and is propagated via tissue culture and root cuttings, maintaining stability through successive asexual propagations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing raspberry varieties are used, then certain characteristics are maintained, but high productivity combined with partial self-fruitfulness and medium-sized bright red berries is not achieved
Solution Approach 1:
The patent applies parameter changes by crossing two parental varieties with different genetic parameters to produce offspring with optimized characteristics. The cross between 'Driscoll Maravilla' and 'Driscoll Francesca' resulted in 'DrisRaspSix' which exhibits high productivity and partial self-fruitfulness, demonstrating how changing genetic parameters through breeding can resolve the contradiction between productivity and adaptability.
2Quantity of substance
If large berries are produced, then fruit size is increased, but medium-sized berries with high productivity are not achieved
Solution Approach 1:
The patent resolves this contradiction by changing the genetic parameters through controlled crossing. The resulting variety 'DrisRaspSix' produces medium-sized berries (not excessively large) while maintaining high productivity, achieving an optimal balance between fruit size and yield quantity that neither parent variety alone could provide.
