Raspberry Cultivar ABB 127 Compact Habit High Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing raspberry cultivars lack a combination of compact growth habit, high fruit production, uniform fruit size, and good postharvest longevity, as well as being resistant to environmental variations and pests.
Innovation Solution
A new raspberry cultivar 'ABB 127' is developed through cross-pollination of Rubus idaeus 'Advabertwee' and 'Advabemap', exhibiting a compact, upright growth habit, high fruit production, and improved fruit characteristics such as reddish-orange color, sweet taste, and long postharvest longevity, with enhanced resistance to Downy Mildew and Red Spider Mites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional raspberry cultivars are grown, then fruit production is achieved, but plant habit becomes sprawling and less compact
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that result in a compact, upright growth habit while maintaining high fruit production. The cultivar 'ABB 127' exhibits altered growth parameters compared to traditional cultivars, achieving a bushy form with reduced horizontal spread while preserving productive capacity through controlled environmental conditions and selective breeding.
2Productivity
If raspberry plants are bred for high fruit production, then productivity increases, but postharvest longevity of fruits decreases
Solution Approach 1:
The patent applies local quality by developing a cultivar where specific local characteristics of the fruit (such as skin thickness, sugar content distribution, and acid balance) are optimized to enhance postharvest longevity. The 'ABB 127' cultivar produces fruits with uniform drupelet size and enhanced firmness in specific regions, allowing the fruit to maintain quality longer after harvest while still achieving high production volumes through proper canopy management and fertilization.
3Manufacturing precision
If raspberry plants are grown in controlled environments, then uniform fruit quality is achieved, but adaptability to environmental variations decreases
Solution Approach 1:
The patent applies preliminary action by pre-acclimatizing the 'ABB 127' cultivar to specific environmental conditions during the breeding and propagation process. The plants are gradually exposed to controlled variations in temperature, humidity, and light before full production, building inherent resilience. This preliminary conditioning allows the cultivar to maintain uniform fruit quality across a broader range of environmental conditions without requiring intensive ongoing environmental control.
4Volume of moving object
If compact plant habit is selected, then plant size is reduced, but fruit size may decrease
Solution Approach 1:
The patent applies dynamics by creating a cultivar where the relationship between plant size and fruit size is decoupled. The 'ABB 127' cultivar exhibits dynamic resource allocation, directing sufficient nutrients and energy to fruit development despite the compact overall plant structure. Through controlled fertilization and pruning, the plant dynamically adjusts its resource distribution to maintain both compact habit and large fruit size, achieving approximately 2.5 cm diameter fruits on a reduced plant frame.
