Coleus Balflamobin Cultivar Unique Foliage Coloration and Sun Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Coleus cultivars lack unique foliage coloration, leaf shape, and sun tolerance, with limited options for compact, upright growth habits.
Innovation Solution
The development of the 'Balflamobin' cultivar of Plectranthus scutellarioides, resulting from controlled breeding, which features medium purplish-red and dark greyed-red foliage, moderately vigorous upright growth, and improved sun tolerance, distinguished by leaf and petiole pubescence and smaller foliage size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing Coleus cultivars are used, then common foliage coloration and leaf shape are obtained, but unique foliage coloration and leaf shape are lacking
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar with specific genetic parameters that produce unique foliage coloration (medium purplish-red and dark greyed-red) and leaf shape characteristics. The controlled breeding program modified the genetic parameters of the parent plant to achieve these distinctive traits while maintaining consistency through true-to-type asexual propagation.
2Area of moving object
If larger foliage is produced, then visual impact is improved, but compact and upright growth habit is compromised
Solution Approach 1:
The patent applies local quality by creating a cultivar with smaller foliage dimensions (approximately 4.5 cm length and 2.0 cm width) that maintains an aesthetically pleasing appearance while supporting a compact, upright growth habit. The pubescent texture on leaves and petioles adds visual interest that compensates for the reduced size, allowing the plant to achieve both visual impact and desired growth form.
3Adaptability or versatility
If sun tolerance is improved, then outdoor performance is enhanced, but foliage coloration may be compromised
Solution Approach 1:
The patent applies feedback mechanisms through the plant's adaptive response to sunlight exposure. The foliage coloration (medium purplish-red and dark greyed-red) has been bred to maintain stability under varying light conditions, with the pubescent texture providing additional protection against UV radiation while preserving color integrity. The controlled breeding program selected for both sun tolerance and color stability simultaneously.
4Reliability
If asexual propagation is used, then true-to-type reproduction is achieved, but genetic diversity is reduced
Solution Approach 1:
The patent applies preliminary action by establishing the desired genetic characteristics through controlled breeding and selection before propagation. The unique foliage coloration, leaf shape, and growth habit traits were firmly established in the parent plant through prior breeding work, ensuring that asexual propagation by terminal stem cuttings would reliably reproduce these pre-determined characteristics without requiring further genetic variation.
