Aster Synpin Henfirst Cultivar Traits and Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Aster hybrida that exhibits distinct and stable characteristics such as medium-sized, long-lasting double-type inflorescences with specific coloration, foliage, and growth habits, which are not adequately met by existing varieties like 'Victoria Celeste'.
Innovation Solution
The development of 'Synpin Henfirst', a cultivar resulting from a natural mutation of 'Synhen Thefirst', characterized by medium-sized, long-lasting double-type inflorescences with purple-violet ray florets, dark yellow-green foliage, and an upright, freely branched growth habit, achieved through asexual reproduction and selected for its unique traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Aster varieties like 'Victoria Celeste' are used, then they provide certain ornamental characteristics, but they do not exhibit the desired combination of medium-sized long-lasting double-type inflorescences with specific purple-violet coloration and dark yellow-green foliage
Solution Approach 1:
The patent applies parameter changes by selecting for specific phenotypic parameters including purple-violet ray floret color (RHS N81A), dark yellow-green foliage (RHS 147A), medium-sized inflorescences (3.2-3.3 cm diameter), and early September flowering time. These parameter specifications create a distinct cultivar with stable, reproducible characteristics through asexual propagation.
2Volume of moving object
If larger inflorescences are selected, then visual impact is improved, but the parent cultivar 'Synhen Thefirst' shows slightly larger inflorescences with lighter colored ray florets and lighter green foliage, lacking the desired color intensity and medium size
Solution Approach 1:
The patent applies local quality by specifying particular color characteristics for different plant parts: purple-violet ray florets (RHS N81A), dark yellow-green foliage (RHS 147A), and white roots (RHS N155B but whiter). This localized quality specification ensures each part of the plant exhibits the desired trait intensity while maintaining overall plant balance and medium-sized inflorescences.
3Adaptability or versatility
If natural mutation is utilized to create variety, then unique characteristics are achieved, but the mutation must be firmly fixed and retained through successive generations of asexual reproduction
Solution Approach 1:
The patent employs vegetative cuttings as a propagation method that is both economical and effective for fixing mutations. The cutting propagation process (rooting in 10-18 days at 22°C) creates genetically identical copies that firmly fix the mutant characteristics, ensuring stable inheritance through successive generations without the complexity of seed propagation.
4Reliability
If distinct characteristics are selected for a new cultivar, then the variety becomes unique, but garden performance and weather tolerance must also be maintained at very good levels
Solution Approach 1:
The patent achieves multi-functionality by selecting for a combination of traits that simultaneously provide distinctiveness and adaptability: medium-sized long-lasting double-type inflorescences with purple-violet coloration, dark yellow-green foliage, upright freely branched rounded habit, and very good garden performance and weather tolerance. This universal cultivar performs multiple functions including ornamental value, environmental adaptability, and stable propagation.
