Raspberry Cultivar ABB 118 Breeding for Yield and Longevity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing raspberry cultivars lack desirable traits such as high fruit production, uniformity, and post-production longevity, as well as variations in flowering and fruiting responses under different environmental conditions.
Innovation Solution
The development of a new raspberry cultivar, 'ABB 118', resulting from a cross-pollination between Rubus idaeus 'Advaberimar' and a proprietary selection of Rubus idaeus, exhibiting upright and bushy growth, high fruit production, early flowering and fruiting, darker red-purple fruit color, and good postharvest longevity, achieved through asexual reproduction by root cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing raspberry cultivars are used, then basic fruit production is achieved, but high fruit production, uniformity, and postproduction longevity are not attained
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific genetic traits that alter the plant's physiological parameters. The new cultivar 'ABB 118' exhibits changed parameters including earlier flowering and fruiting timing, darker red-purple fruit color, and improved postharvest longevity through genetic selection and asexual reproduction that maintains these optimized parameters across generations
2Productivity
If raspberry plants are bred for early flowering and fruiting, then productivity is improved, but stability of traits under varying environmental conditions may be compromised
Solution Approach 1:
The patent applies preliminary action by conducting extensive preliminary breeding work and selection over multiple years (discovered in 2012, asexually reproduced since spring 2013) to establish the desired traits before commercial deployment. The asexual reproduction method ensures that the early flowering and fruiting traits are fixed and stabilized in the genome, preventing variation under different environmental conditions
Solution Approach 2:
The patent applies copying through asexual reproduction by root cuttings, which creates genetically identical copies of the selected plant. This cloning process ensures that the early flowering and fruiting traits are perfectly replicated across all propagules, maintaining trait stability and uniformity in the new cultivar 'ABB 118'
