Raspberry Plant ABB 132 Breeding for Yield and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new, stable, and high-yielding raspberry plant varieties that are agronomically sound, particularly for commercial cultivation, as existing varieties may lack consistency in traits like earliness, productivity, and disease resistance.
Innovation Solution
The new raspberry variety 'ABB 132' is developed through sexual crossing and subsequent asexual propagation, exhibiting early autumn production, high productivity, and resistance to mildew and spider mites, with characteristics such as light red fruit color, strong regrowth, and wide adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional raspberry varieties are used for commercial cultivation, then established cultivation methods can be applied, but consistency in traits like earliness, productivity, and disease resistance is insufficient
Solution Approach 1:
The patent applies preliminary action by conducting extensive preliminary breeding work to develop 'ABB 132' with predetermined and consistent traits. The variety was developed through controlled crossing between selected parents ('22' and '211157-009') and evaluated over multiple years (2014-2018) before commercial release, ensuring trait consistency is established in advance rather than discovered after cultivation begins
Solution Approach 2:
The patent applies parameter changes by modifying key agronomic parameters of the raspberry variety through controlled breeding. 'ABB 132' exhibits specific parameter values including early autumn fruiting timing, high productivity rates, and enhanced disease resistance compared to traditional varieties, thereby resolving the contradiction between reliability and productivity
2Productivity
If new raspberry varieties are developed to improve earliness and productivity, then commercial value increases, but stability and agronomic soundness may be compromised
Solution Approach 1:
The patent applies preliminary action by conducting multi-year stability testing of the new variety 'ABB 132' under controlled conditions before commercial release. The variety was evaluated for four years (2014-2018) to confirm consistent expression of productivity and earliness traits, ensuring stability is verified in advance
Solution Approach 2:
The patent applies copying through asexual propagation by cuttings to produce genetically identical copies of the selected plant. This ensures that the high-yielding and early-fruiting traits are precisely replicated across all commercial plants, maintaining variety stability while achieving improved productivity
3Productivity
If raspberry varieties with high productivity are selected, then commercial收益 increases, but resistance to diseases like mildew and spider mites may be reduced
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific disease resistance parameters alongside productivity. The parental selection and subsequent evaluation focused on maintaining both high yield potential and resistance to mildew and spider mites, achieving a favorable parameter combination that resolves the contradiction
