AUSlofty Rose Shrub Repeat Flowering Apricot Fragrance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rose cultivars lack a variety that consistently produces healthy, repeat-flowering apricot blooms with a strong fragrance and vigorous upright growth habit.
Innovation Solution
The development of the Rosa hybrida shrub variety 'AUSlofty', which is bred for its apricot blooms with a strong fragrance and vigorous upright growth, achieved through asexual reproduction by budding and grafting, using Rosa cv. 'Dr. Huey' and Rosa dumetorum cv. 'Laxa' as rootstocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rose cultivars are used, then variety and availability are maintained, but the specific combination of healthy repeat-flowering apricot blooms with strong fragrance and vigorous upright growth is not achieved
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific floral characteristics including apricot coloration, strong fragrance intensity, and repeat-flowering reliability. The breeding process modified multiple parameters simultaneously to achieve the desired combination of traits that distinguish 'AUSlofty' from conventional cultivars.
2Manufacturing precision
If breeding for specific flower characteristics is pursued, then unique floral traits are achieved, but growth vigor and plant health may be compromised
Solution Approach 1:
The patent merges multiple desirable traits from different parent plants to achieve both precise floral characteristics and vigorous growth. By combining apricot coloration, strong fragrance, repeat-flowering ability, and upright growth habit in a single cultivar, the invention resolves the contradiction between specialization and overall plant strength.
3Reliability
If asexual reproduction by budding and grafting is used, then true-to-form propagation is achieved, but dependency on specific rootstocks is created
Solution Approach 1:
The patent uses rootstocks as intermediary plants that provide vigor and disease resistance while the scion provides the desired floral characteristics. This intermediary approach allows the propagation of true-to-form flowers while benefiting from the robust physiology of specialized rootstock plants.
