Emily Carr Rose Mildew Resistance Cold Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rose varieties lack resistance to mildew, consistent flowering, and cold tolerance, as well as desirable color and growth habits.
Innovation Solution
The development of the 'Emily Carr' rose variety, resulting from a specific hybridization program, which exhibits resistance to mildew, almost continuous flowering, deep red semi-double flowers, and cold tolerance, achieved through asexual reproduction by softwood cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing rose varieties are used, then they have basic flowering capability, but they lack resistance to mildew and cold tolerance
Solution Approach 1:
The patent applies composite breeding by crossing two different rose varieties ('Morden Cardinette' and 'Cuthbert Grant') to create a new variety that combines desirable traits from both parents, including mildew resistance and cold tolerance, achieving a composite genetic structure that provides both reliability and adaptability
2Duration of action of stationary object
If existing rose varieties are used, then they have some flowering capability, but they lack almost continuous flowering and desirable color
Solution Approach 1:
The patent achieves extended flowering duration through selective breeding that modifies genetic parameters controlling flowering cycles, resulting in a variety that flowers almost continuously from early summer to first frost, with consistent deep red coloration throughout the extended flowering period
3Strength
If existing rose varieties are used, then they have basic growth habits, but they lack vigorous upright growth
Solution Approach 1:
The patent achieves vigorous upright growth through selective breeding that enhances specific local characteristics including stem strength, thorn density for structural support, and overall plant architecture, creating a robust upright growth habit that maintains strength throughout the plant structure
