Raspberry Plant PS-06.024-27 Mid-Season Primocane Fruiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new raspberry variety that can thrive in the specific climate and growing conditions of the central coast of California, producing fruit consistently from July to December on primocanes and from May to July on floricanes, with unique characteristics such as mid-season primocane fruiting, always 3-foliate leaves, medium red fruit color, and medium thorn density, which are not adequately met by existing varieties.
Innovation Solution
The development of a new raspberry variety, 'PS-06.024-27', resulting from a controlled cross between 'PS-1049' and 'PS-3123', which is adapted to the central coast of California's climate, exhibiting mid-season primocane fruiting, always 3-foliate leaves, medium red fruit color, and medium thorn density, and is asexually propagated to ensure consistent trait expression across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing raspberry varieties are used, then general fruit production is maintained, but mid-season primocane fruiting with consistent 3-foliate leaves and medium thorn density is not achieved
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific trait combinations: mid-season primocane fruiting timing, always 3-foliate leaf structure, medium thorn density, and medium red fruit color. These parameter specifications create a distinct variety adapted to central coast California climate conditions while ensuring reliable trait expression through asexual propagation.
2Reliability
If asexual propagation is used to ensure consistent trait expression, then reliability of traits is improved, but genetic diversity is reduced
Solution Approach 1:
The patent applies preliminary action by performing controlled cross-pollination between selected parent plants ('PS-1049' and 'PS-3123') to create the desired genetic combination before asexual propagation. This preliminary sexual reproduction step generates the target genotype with mid-season primocane fruiting and always 3-foliate leaves, which is then fixed through asexual propagation to ensure reliable trait consistency in subsequent generations.
3Productivity
If the variety is adapted to central coast California climate for year-round production, then productivity is improved, but adaptability to other climates may be limited
Solution Approach 1:
The patent applies local quality by optimizing the raspberry variety specifically for central coast California climate conditions, achieving mid-season primocane fruiting and year-round production (July-December on primocanes, May-July on floricanes). The variety exhibits local adaptation through selected traits including medium red fruit color, medium thorn density, and always 3-foliate leaves, which are optimized for this specific geographic region's temperature and growing conditions.

AI summary
This invention relates to a new and distinct everbearing variety of raspberry plant named ‘PS-06.024-27’. The new variety is primarily adapted to the growing conditions of the central coast of California and is characterized by the following: mid-season primocane production with medium sized fruit of medium red coloration and medium gloss. Fruit is of consistent conic shape, weak adherence of receptacle and is of good flavor. Foliage is strongly concave, medium green; possessing weak rugosity and always 3 foliates. Primocanes have a strong waxy coat, medium thorn density and weak to medium anthocyanin coloration.
