Driscoll Pacifica Raspberry Cultivar Yield and Firmness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing raspberry cultivars often lack high yields, firm fruit, and consistent flavor, with issues such as poor post-harvest fruit rot resistance and variable fruit color.
Innovation Solution
The development of the 'Driscoll Pacifica' red raspberry cultivar, botanically identified as Rubus idaeus L., which exhibits high yields, firm and flavorful fruit, and easy separation from the receptacle, achieved through hybridization and asexual propagation methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing raspberry cultivars are used, then cultivation is simple, but yields are low and fruit firmness is poor
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar with modified genetic parameters through hybridization. The 'Driscoll Pacifica' cultivar exhibits changed parameters including higher yield (39), improved fruit firmness (14), and enhanced post-harvest resistance (27) compared to existing cultivars, resolving the contradiction between productivity and reliability.
2Reliability
If existing raspberry cultivars are used, then cultivation method is established, but fruit flavor consistency is variable
Solution Approach 1:
The patent applies copying through asexual propagation methods (tissue culture, root suckers, root cuttings) that create genetic copies of the selected superior plant. This ensures flavor consistency (27) is maintained across generations while the propagation complexity (36) is managed through established horticultural techniques.
3Reliability
If existing raspberry cultivars are used, then growth habit is established, but post-harvest fruit rot resistance is poor
Solution Approach 1:
The patent applies preliminary action by selecting and propagating plants with inherent resistance traits before harvest. The 'Driscoll Pacifica' cultivar was selected for its superior post-harvest resistance characteristics, and this resistance is maintained through asexual propagation, ensuring both productivity (39) and reliability (27) are improved simultaneously.
