Thornless Dwarf Rosa ROP007 Cultivar for Container Gardening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rose cultivars often have thorny stems, larger flower sizes, and less compact growth habits, which can make them less suitable for container and landscape gardening, particularly for desired traits of dwarf habit, prolific flowering, and thornlessness.
Innovation Solution
A new cultivar 'ROP007' of hybrid rose with thornless stems, a dwarf plant habit, and abundant small pink flowers with white centers, bred through asexual propagation by stem cuttings, combining these characteristics to create a unique and stable cultivar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If existing rose cultivars are used, then larger flower sizes are achieved, but thorny stems and less compact growth habits result
Solution Approach 1:
The invention extracts and eliminates the thorny stem characteristic from the rose cultivar while retaining the desirable flowering properties. Through selective breeding and asexual propagation, the thorns are removed from the plant's genetic expression, leaving a thornless stem structure that maintains the cultivar's flowering capabilities.
Solution Approach 2:
The invention changes the physical parameters of the rose cultivar by producing smaller flowers (1-2 cm diameter compared to larger traditional roses) while simultaneously changing the stem parameter from thorny to thornless. This parameter transformation creates a new cultivar profile optimized for container gardening and landscape use.
2Stability of the object's composition
If existing rose cultivars are used, then traditional growth habits are maintained, but dwarf plant habit and prolific flowering are not achieved
Solution Approach 1:
The invention creates a dynamic growth habit where the plant maintains a compact, dwarf form (10-20 cm height) while exhibiting continuous, prolific flowering. The plant's growth pattern is dynamically optimized to produce multiple flushes of flowers throughout the growing season, with the ability to rebloom after pruning, creating an adaptable and productive landscape plant.
Solution Approach 2:
The invention merges multiple desirable traits into a single cultivar: dwarf stature, thornless stems, prolific flowering, and continuous blooming capability. By combining these characteristics that are typically found in separate rose varieties, the invention creates a unified cultivar that excels in container and landscape applications.
3Productivity
If rose cultivars with abundant blooming are selected, then flower quantity increases, but fruit production may occur
Solution Approach 1:
The invention extracts and eliminates the fruit production capability from the rose cultivar while maintaining abundant flowering. Through selective breeding, the developmental pathway that leads to fruit formation is removed or suppressed, resulting in a cultivar that produces numerous flowers but does not develop fruits, thereby concentrating the plant's energy on floral production.
