Miniature Rose Cultivar for Abundant Flowers and Compact Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rose cultivars lack uniform and abundant mauve pink flowers with long shelf-life, suitability for commercial production in containers, early flowering, and vigorous yet compact growth when propagated on their own roots.
Innovation Solution
Development of a new rose variety, 'Poulty041', resulting from controlled crossing, which exhibits mauve pink flowers, early flowering, and compact growth, with resistance to diseases and tolerance to various environmental conditions, suitable for commercial production in containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing rose cultivars are used for commercial production, then they can be grown in containers, but they lack uniform and abundant mauve pink flowers with long shelf-life
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific floral characteristics including mauve pink coloration, uniform petal structure, and extended vase life. The cultivar 'Poulty041' was developed through controlled crossing and selection to achieve specific parameter values for flower color (Red-Purple Group 69B), petal count (40 petals), and duration (21 days on plant) that simultaneously satisfy multiple commercial requirements
2Productivity
If rose varieties are bred for vigorous growth, then they produce abundant flowers, but they become less suitable for container production
Solution Approach 1:
The patent resolves this contradiction by changing the growth parameter through selective breeding to achieve a compact habit with specific dimensions (25 cm height, 40 cm width at 12 months) while maintaining high flower production capacity. The cultivar produces 3-5 flowers per branch with 40 petals each, achieving abundant floral output within a container-appropriate size framework
3Loss of time
If rose varieties are bred for early flowering, then they meet market timing requirements, but they may compromise on growth vigor
Solution Approach 1:
The patent applies parameter changes by selecting for early flowering capability while maintaining vigor through controlled breeding. The cultivar achieves continuous blooming with flowers lasting 21 days on the plant and producing 3-5 flowers per branch, balancing early market entry with sustained productive output throughout the growing season
