Raspberry Plant ABB 135 Breeding for Yield and Firmness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new, stable, high-yielding, and agronomically sound raspberry plant varieties that excel in earliness, fruit size, and firmness, with improved branching ability and lower chill requirements, as existing varieties may lack these desirable traits.
Innovation Solution
The new raspberry variety 'ABB 135' is developed through a sexual cross between 'Advabertwee' and '211150-009', exhibiting early double cropping, high productivity, light red fruit color, and firm fruit, with asexual reproduction demonstrating stability through successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional raspberry varieties are used, then they can be grown in various conditions, but they lack desirable traits such as earliness, fruit size, and firmness
Solution Approach 1:
The patent applies parameter changes by developing a new raspberry variety 'ABB 135' with specific improved parameters including earliness (earlier fruiting), fruit size (larger berries), and firmness (more firm fruit). The variety was bred to have lower chill requirements and enhanced branching ability, representing deliberate changes in biological parameters to achieve superior productivity while maintaining variety stability through controlled asexual propagation
2Adaptability or versatility
If raspberry plants are propagated sexually, then genetic diversity is achieved, but stability of morphological characteristics is reduced
Solution Approach 1:
The patent applies preliminary action by first performing sexual cross-breeding between parent plants 'Advabertwee' and '211150-009' to create a selection with desired traits, then subsequently propagating this selected variety asexually through cuttings. This preliminary sexual crossing followed by asexual propagation ensures both genetic improvement and stable inheritance of morphological characteristics including light red fruit color, firmness, and early double cropping ability
3Reliability
If raspberry varieties require high chill hours, then they can maintain dormancy and health, but their adaptability to diverse growing conditions is limited
Solution Approach 1:
The patent applies parameter changes by developing variety 'ABB 135' with reduced chill requirements compared to traditional varieties. This parameter change in chill hour requirements expands the adaptability of the raspberry plant to diverse growing conditions including warmer climates, while still maintaining the ability to undergo proper dormancy and bud break cycles for healthy growth
