Shrub Rose VLR003 Breeding for Stable Petal Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of shrub rose plant that combines attractive yellow double petal flowers, a compact semi-upright growth habit, and dark green glossy foliage, which is stable and homogeneous across generations, suitable for ornamental purposes in various landscapes.
Innovation Solution
The new variety 'VLR003' (YUKON SUN™) is created through controlled breeding of 'BAline' and '282', exhibiting 17 petals per flower, semi-upright compact growth, and dark green glossy foliage, achieved through asexual propagation using vegetative cuttings, distinguishing it from its parents and other similar varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If controlled breeding of 'BAline' and '282' is performed, then the new variety 'VLR003' with 17 petals per flower is obtained, but the petal number is intermediate between the parents (32 petals in 'BAline' and 11 petals in '282')
Solution Approach 1:
The patent applies parameter changes by selecting and fixing the petal number parameter at 17 petals per flower, which is an intermediate value between the parents ('BAline' with 32 petals and '282' with 11 petals). This intermediate parameter creates a new stable characteristic in the offspring variety that is distinct from both parents while maintaining consistency across generations through asexual propagation.
2Stability of the object's composition
If asexual propagation by vegetative cuttings is used, then homogeneous and stable characteristics are maintained, but the variety cannot be bred with other varieties
Solution Approach 1:
The patent applies the copying principle by using asexual propagation through vegetative cuttings to create exact genetic copies of the 'VLR003' variety. This ensures that the characteristics (17 petals per flower, semi-upright compact growth, dark green glossy foliage) remain homogeneous and stable across generations, while the variety maintains its distinctiveness from parents and other varieties.
3Adaptability or versatility
If the new variety is distinguished from its ancestors, then variety uniqueness is achieved, but the differentiation process becomes complex
Solution Approach 1:
The patent applies segmentation by identifying and emphasizing specific distinguishing characteristics that separate 'VLR003' from its ancestors. The key differentiating features include: 17 petals per flower (intermediate between parents), semi-upright compact growth habit, and dark green glossy foliage. By segmenting the phenotype into these distinct traits, the variety achieves clear differentiation from parents ('BAline' with 32 petals, '282' with 11 petals) and other similar varieties without requiring complex analysis.
