REDLAM Cherry Tree Breeding for Shelf Life and Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a cherry tree variety that produces fruits with a long shelf life, good eating quality, and specific color characteristics, suitable for commercial fresh market production, particularly in regions with Mediterranean climate conditions.
Innovation Solution
The development of the 'REDLAM' cherry tree variety, resulting from a cross between 'ASF 9904' and 'ROSILAM', which is propagated by grafting on 'Maxma14' rootstock, offering unique fruit and tree characteristics such as medium to large size, firmness, semi-sweet flavor, orange-yellow flesh with red pigmentation, and resistance to cracking, suitable for early to medium maturity in the South of France.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cherry tree varieties are selected for early ripening, then productivity is improved, but shelf life is reduced
Solution Approach 1:
The patent applies parameter changes by selecting and breeding cherry tree varieties with specific genetic characteristics that simultaneously achieve early ripening and extended shelf life. The 'REDLAM' variety was developed through controlled pollination between 'ASF 9904' and 'ROSILAM' to optimize parameters including ripening time, fruit firmness, and storage durability, resulting in a variety that ripens early but maintains quality for extended periods both on-tree and after harvest.
2Duration of action of stationary object
If cherry fruits are bred for firmness, then shelf life is improved, but eating quality may deteriorate
Solution Approach 1:
The patent resolves this contradiction by carefully balancing multiple parameters through selective breeding. The 'REDLAM' variety was developed to achieve optimal firmness for shelf life while maintaining flesh texture, flavor, and juiciness for eating quality. The controlled cross between 'ASF 9904' and 'ROSILAM' selected for progeny exhibiting both firm fruit structure and superior sensory attributes, demonstrating that parameter optimization can simultaneously improve durability and edibility.
3Productivity
If cherry tree variety is developed for specific color characteristics, then market suitability is improved, but adaptability to different climatic conditions may be reduced
Solution Approach 1:
The patent addresses this contradiction by selecting parent varieties with complementary traits and breeding for balanced expression of color characteristics alongside climatic resilience. The 'REDLAM' variety was developed through controlled pollination between 'ASF 9904' and 'ROSILAM' to achieve distinctive red pigmentation on yellow background that appeals to consumers, while simultaneously selecting for adaptability to Mediterranean climate conditions including heat tolerance and irregular precipitation patterns.
