Grandiflora Rose 'WEKfunk' Breeding for Stem Length and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rose cultivars lack a variety with unique cream and cherry blushed burgundy flower coloration, abundant blooms on long cutting stems, and a tall upright moderately spreading growing habit, which are desirable for outdoor garden decoration.
Innovation Solution
The development of a new Rosa hybrida variety, 'WEKfunk', which features cream and cherry blushed burgundy double flowers, abundant blooms on long stems, and a tall upright moderately spreading growth habit, distinguishable from its parents and closest commercially available cultivars, and can be asexually propagated through budding and grafting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a rose cultivar has abundant blooms on long cutting stems, then it is suitable for floral arrangements and outdoor decoration, but it may have a shorter growing habit that limits garden versatility
Solution Approach 1:
The rose cultivar exhibits dynamic adaptability in its growing habit, transitioning between upright and spreading forms depending on environmental conditions and pruning practices, allowing it to maintain long cutting stems while adapting to different garden spaces and configurations
2Ease of manufacture
If a rose cultivar has unique cream and cherry blushed burgundy flower coloration, then it provides distinctive visual appeal, but such unique coloration may reduce disease resistance compared to conventional varieties
Solution Approach 1:
The rose cultivar combines unique cream and cherry blushed burgundy coloration with robust health characteristics through selective breeding, creating a composite genetic makeup that simultaneously achieves distinctive visual appeal and enhanced disease resistance against powdery mildew and rust
3Quantity of substance
If a rose cultivar has double flowers with about 15 to 22 petals, then it achieves a fuller bloom appearance, but it requires more resources and maintenance compared to varieties with fewer petals
Solution Approach 1:
The rose cultivar optimizes the petal parameter to range from 15 to 22 petals per bloom, achieving a fuller appearance while maintaining resource efficiency through balanced nutrient allocation and moderate blooming frequency that does not deplete plant resources
4Illumination intensity
If a rose cultivar has an upright moderately spreading tall growing habit, then it provides vertical garden interest, but it requires more space compared to compact varieties
Solution Approach 1:
The rose cultivar grows primarily in the vertical dimension with an upright moderately spreading habit reaching 180-200 cm in height, providing vertical garden interest while maintaining a relatively compact footprint that minimizes horizontal space requirements
