Syringa Annys200809 Cultivar Breeding and Grafting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Syringa that combines compact plant habit, large flower panicles, sweet fragrance, repeat blooming, and distinctive red-purple flowers with white petal lobes, which are not adequately met by existing lilac varieties.
Innovation Solution
The development of the Syringa 'Annys200809' cultivar, which exhibits a compact plant habit, large flower panicles, sweet fragrance, repeat blooming, and red-purple flowers with white petal lobes, achieved through asexual propagation by grafting, distinguishing it from other lilac varieties like 'Pink Perfume' and 'Penda'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new Syringa cultivar is developed to combine multiple desirable traits (compact habit, large flower panicles, sweet fragrance, repeat blooming, distinctive coloration), then the ornamental value and versatility are improved, but the complexity of breeding and selection process increases
Solution Approach 1:
The patent combines multiple desirable traits (compact plant habit, large flower panicles, sweet fragrance, repeat blooming, and distinctive red-purple flowers with white petal lobes) into a single new cultivar 'Annys200809'. This merging of traits through controlled breeding and selection resolves the technical contradiction by achieving ornamental versatility while managing breeding complexity through systematic parental selection and asexual propagation.
Solution Approach 2:
The patent uses asexual propagation by grafting to create exact copies of the new cultivar 'Annys200809'. This copying method ensures that the complex combination of traits is replicated precisely without requiring repeated breeding cycles, thereby reducing the complexity of propagating the multi-trait cultivar while maintaining ornamental versatility.
2Adaptability or versatility
If existing lilac varieties are used, then the breeding process is simpler, but they lack the unique combination of compact size, large flower panicles, sweet fragrance, repeat blooming, and distinctive coloration
Solution Approach 1:
The patent applies local quality by selecting specific parental varieties with complementary traits: 'Pink Perfume' provides compact plant habit and sweet fragrance, while the unknown male parent contributes large flower panicles, repeat blooming capability, and distinctive red-purple flowers with white petal lobes. This targeted selection of local traits from different parents resolves the contradiction by achieving unique trait combination while maintaining reasonable breeding ease through deliberate parental choice.
3Stability of the object's composition
If sexual reproduction is used to create genetic variation, then new trait combinations are achieved, but genetic stability and trait consistency in successive generations are reduced
Solution Approach 1:
The patent performs preliminary action by conducting sexual reproduction and trait selection during the breeding phase to create the desired trait combination in the new cultivar 'Annys200809'. Once the optimal trait combination is achieved through this preliminary breeding process, asexual propagation by grafting is used to fix and stabilize these traits. This preliminary creation of genetic variation followed by stabilization through cloning resolves the contradiction between genetic stability and trait variability.
Solution Approach 2:
The patent uses asexual propagation by grafting to create genetically identical copies of the new cultivar 'Annys200809'. This copying process ensures that the unique combination of traits (compact habit, large flower panicles, sweet fragrance, repeat blooming, and distinctive coloration) is replicated with high fidelity across successive generations, resolving the contradiction by maintaining both genetic stability and the desired trait variability established during breeding.
