PARAGON Raspberry Plant Early Primocane Fruiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing raspberry varieties do not consistently exhibit early primocane fruiting, strong rugosity, high fruit gloss, and excellent flavor, which are desirable traits for adaptability and consumer preference.
Innovation Solution
The development of a new raspberry variety, 'PARAGON', resulting from a controlled cross between 'GRANDEUR' and 'PS-3890', which exhibits early primocane fruiting, very strong rugosity, light red fruit color, high fruit gloss, and excellent flavor, adapted to the central coast of California's climate and growing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing raspberry varieties are used, then general adaptability is maintained, but early primocane fruiting, strong rugosity, high fruit gloss, and excellent flavor are not consistently exhibited
Solution Approach 1:
The patent combines multiple desirable traits (early primocane fruiting, strong rugosity, high fruit gloss, excellent flavor, and adaptability) into a single integrated variety through controlled cross-breeding between 'GRANDEUR' and 'PS-3890'. This merging of previously separate trait combinations resolves the contradiction by creating a unified genotype that reliably expresses all desired characteristics simultaneously.
Solution Approach 2:
The patent changes the genetic parameters of the raspberry variety through selective breeding to achieve a new combination of traits. By modifying the genetic composition through controlled crossing and selecting for specific phenotypic expressions, the variety 'PARAGON' achieves reliable expression of early fruiting, strong rugosity, high gloss, and excellent flavor while maintaining adaptability.
2Adaptability or versatility
If a new variety is developed through controlled cross-breeding, then unique combination of traits is achieved, but breeding complexity and time investment increase
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-breeding between specifically selected parent varieties ('GRANDEUR' and 'PS-3890') that are known to possess complementary desirable traits. This preliminary selection and crossing, followed by systematic evaluation of progeny, streamlines the breeding process by pre-establishing the genetic foundation for the desired trait combination, reducing overall program complexity.
Solution Approach 2:
The patent employs feedback mechanisms through extensive field testing and evaluation of the new variety over multiple years and locations. By systematically observing and measuring the expression of desired traits in the progeny and comparing them against breeding objectives, the program can confirm whether the unique combination of traits has been successfully achieved, allowing for course correction if needed.
3Reliability
If extensive field testing is conducted over multiple years, then trait fixation and true-to-type reproduction are confirmed, but time and resource investment increase
Solution Approach 1:
The patent applies partial action by conducting field tests across multiple representative locations and years rather than attempting to test every possible environmental condition. This approach confirms trait fixation and true-to-type reproduction under diverse but representative conditions, achieving sufficient reliability without the excessive time investment of exhaustive testing.
Solution Approach 2:
The patent allows the new variety to demonstrate its own stability and true-to-type reproduction through natural expression of traits across multiple generations of asexual reproduction. By propagating the variety through dormant canes, roots, and cuttings and observing consistent trait expression in successive generations under field conditions, the variety self-validates its reliability without requiring artificial intervention or acceleration of the testing process.

AI summary
This invention relates to a new and distinct everbearing variety of raspberry plant named ‘PARAGON’. The new variety is primarily adapted to the growing conditions of the central coast of California and is characterized by the following: early primocane production with medium sized fruit of light-red coloration and high gloss. Fruit is of consistent conic shape, medium adherence of receptacle and is of excellent flavor. Foliage is slightly concave, medium green; possessing very strong rugosity and equal 3-5 foliates. Primocanes have an absent or very weak waxy coat, medium thorn density and weak, anthocyanin coloration.
