Regal D5-100 Apple Tree Breeding for Storage Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apple tree varieties face challenges in commercial viability due to inadequate growing characteristics and storage traits, such as fruit pressure, soluble solids, and pH, which affect their success in the fresh market and storage life.
Innovation Solution
The development of the 'Regal D5-100' apple tree, resulting from controlled pollination between Huaguan and Honeycrisp, exhibits unique traits like upright growth, moderate vigor, mid-season blooming, and fruit characteristics that include medium size, streaked bi-color, and four months of storage life, making it suitable for pollination with other diploid apples and resistant to bruising but susceptible to powdery mildew and fireblight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing apple tree varieties are used, then they have established growing characteristics, but they exhibit inadequate storage traits and fruit pressure affecting commercial viability
Solution Approach 1:
The patent combines two existing apple varieties (Huaguan and Honeycrisp) through controlled pollination to create a new variety that integrates desirable traits from both parents, including improved storage life and commercial viability characteristics
Solution Approach 2:
The breeding process modifies key pomological parameters including fruit pressure, soluble solids content, and pH levels to achieve improved storage traits and commercial performance
2Duration of action of stationary object
If apple trees are bred for extended storage life, then storage characteristics improve, but other growing characteristics and fruit quality may be compromised
Solution Approach 1:
The patent systematically adjusts multiple pomological parameters simultaneously, including storage life, fruit pressure, soluble solids, and pH, to achieve a balanced improvement in both storage characteristics and growing traits
Solution Approach 2:
The new apple variety is bred to exhibit multiple desirable characteristics simultaneously, including upright growth habit, moderate vigor, mid-season blooming, and extended storage life, making it adaptable to various commercial orchard conditions
