ENDURANCE Raspberry Plant Late-Season Primocane Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a raspberry variety that can thrive in the specific climate and growing conditions of the central coast of California, producing fruit consistently throughout the year with unique characteristics such as dark purple spines, late fruit yield, medium red fruit color, and fair flavor, which existing varieties like 'GRANDEUR' and 'MAJESTIC' do not fully meet.
Innovation Solution
The development of a new raspberry variety, 'ENDURANCE', resulting from a controlled cross between 'GRANDEUR' and '04.3891', which is adapted to USDA zones 9-10, exhibiting dark purple spines, late fruit yield, medium red fruit color, and fair flavor, and is asexually propagated to maintain consistent traits across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing raspberry varieties like 'GRANDEUR' and 'MAJESTIC' are used, then general adaptability is maintained, but they do not fully meet the specific climate requirements of central coast California and do not produce consistent late fruit yield
Solution Approach 1:
The patent applies local quality by developing a raspberry variety specifically adapted to the central coast California climate through controlled crossing. The variety 'ENDURANCE' exhibits localized adaptations including dark purple spines, late fruit yield, medium red fruit color, and fair flavor that are uniquely suited to this specific geographic region and climate zone, rather than being broadly adapted to multiple environments.
2Duration of action of moving object
If raspberry varieties are bred for extended fruit production season, then fruit production duration is improved, but maintaining consistent traits through successive generations becomes more difficult
Solution Approach 1:
The patent applies preliminary action by performing controlled crossing between selected parent varieties ('GRANDEUR' and '04.3891') before propagation to establish the desired trait combination. The variety was bred with predetermined characteristics including late fruit yield and extended production season, then asexually propagated to fix these traits before commercial deployment, ensuring consistency across generations.
Solution Approach 2:
The patent applies copying through asexual propagation methods (dormant canes, roots, and non-dormant root shoot cuttings) to reproduce the bred variety 'ENDURANCE' with identical genetic material. This copying process maintains trait consistency across successive generations by eliminating genetic recombination that would occur with sexual reproduction, preserving the extended fruit production characteristics.
3Ease of manufacture
If a new raspberry variety is developed with unique characteristics, then product differentiation is improved, but the complexity of breeding and propagation increases
Solution Approach 1:
The patent applies merging by combining desirable traits from two parent varieties through controlled crossing. The variety 'ENDURANCE' merges characteristics from 'GRANDEUR' (adaptability, fruit production) and '04.3891' (late fruit yield, dark purple spines) to create a unified variety with differentiated features including medium red fruit color, fair flavor, and extended production season from July-December on primocanes and May-July on floricanes.

AI summary
This invention relates to a new and distinct everbearing variety of raspberry plant named ‘ENDURANCE’. The new variety is primarily adapted to the growing conditions of the central coast of California and is characterized by the following: late-season primocane production with medium to large sized fruit of medium-red coloration. Fruit is of consistent conic shape, releases easily from receptacle, possesses medium gloss and fair flavor. Foliage is flat to slightly convex, medium green; possessing weak rugosity, weak gloss and equal 3-5 foliates. Primocanes have an absent or very weak waxy coat, medium thorn density of small dark purple spines and have very weak anthocyanin coloration.
