Raspberry ABB 136 Breeding for Yield and Invasiveness
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 those with improved earliness and productivity, as existing cultivars may lack these traits or be invasive.
Innovation Solution
The new raspberry variety 'ABB 136' is developed through a sexual cross between 'Advabertwee' and '211157-6', exhibiting early double cropping, high productivity, light red fruit color, and low chill requirements, and is propagated asexually to maintain its characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional raspberry cultivars are used, then they may be invasive with vigorous spreading, but they lack stability and high yield consistency
Solution Approach 1:
The patent applies parameter changes by selecting and fixing specific genetic traits through controlled breeding to transform the plant's growth parameters. The new variety 'ABB 136' was developed by modifying key parameters such as growth vigor, spreading tendency, and yield consistency through selective crossing and evaluation over multiple years, resulting in a cultivar that maintains high productivity without excessive invasiveness
2Speed
If early maturing varieties are selected, then earliness is improved, but productivity and stability may be compromised
Solution Approach 1:
The patent applies universality by developing a variety that performs multiple functions simultaneously - it achieves early maturation while maintaining high productivity and stability. The variety 'ABB 136' was selected for its ability to combine early fruiting capability with sustained high yields and consistent performance across different growing conditions, making it universally applicable for commercial production
3Strength
If vigorous spreading is allowed, then crop vigor is maintained, but control and management become difficult
Solution Approach 1:
The patent applies local quality by creating a variety with differentiated growth characteristics - it maintains strong vigor in the main cane structure for robust fruit production while having reduced spreading tendency through modified sucker development. This localized differentiation of growth patterns allows the plant to exhibit strength where needed while being more manageable in terms of spread control
