Aster Synbul Henfirst Cultivar Flowering and Foliage Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Aster hybrida that exhibits distinct and durable characteristics such as medium-sized, long-lasting double-type inflorescences with violet ray florets, dark yellow-green foliage, and a specific plant habit, which are not adequately met by existing varieties like 'Milka' in terms of flowering timing and foliage color retention.
Innovation Solution
The development of 'Synbul Henfirst' through asexual reproduction from a natural mutation of 'Synhen Thefirst', characterized by its unique combination of traits including upright, freely branching habit, and prolonged flowering in early to mid-September, which are stable across successive generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If existing varieties like 'Milka' are used, then general garden performance is acceptable, but flowering timing is too late and foliage color retention is insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a natural mutation that exhibits specific phenotypic parameters: early to mid-September flowering timing and dark yellow-green foliage color. The cultivar 'Synbul Henfirst' is characterized by having 40-75 ray florets per inflorescence with violet coloration, and foliage that maintains dark yellow-green coloration throughout the growing season, directly addressing the timing and color retention requirements
2Stability of the object's composition
If asexual reproduction is used to propagate the cultivar, then the distinct characteristics are firmly fixed and retained, but the initial discovery required identifying a single mutation within a large population
Solution Approach 1:
The patent applies copying through asexual reproduction methods, specifically vegetative cuttings taken in June 2008 from the initial selection. This copying process produces multiple plants that are genetically identical to the parent cultivar, ensuring that the distinct characteristics (medium-sized inflorescences, violet ray florets, dark yellow-green foliage, upright habit) are firmly fixed and retained through successive generations without the variability introduced by sexual reproduction
3Stability of the object's composition
If the cultivar is grown in controlled breeding programs, then the characteristics can be stabilized, but the phenotype may vary significantly under different environmental conditions
Solution Approach 1:
The patent applies feedback by conducting horticultural examination of plants grown from cuttings continuously from June 2008 thereafter, monitoring and verifying that the combination of characteristics remains firmly fixed through successive generations. This ongoing evaluation ensures that the cultivar maintains its distinct traits while providing information about its performance under different environmental conditions
