Hosta 'Beckoning' Variegated Leaf Color and Size Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct Hosta cultivar that exhibits unique variegated leaf patterns with a blue-green margin and gold center, differing from existing sports of 'Blue Angel' and other hostas, while maintaining stability in asexual reproduction and displaying robust growth characteristics.
Innovation Solution
The development of the Hosta cultivar 'Beckoning', which is a naturally occurring sport of 'Blue Angel', featuring rugose, pointed heart-shaped leaves with a blue-green margin and gold center, and exhibiting larger size and distinct coloration, achieved through successful propagation by division and tissue culture methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a new Hosta cultivar with unique variegated leaf patterns is developed, then aesthetic value and distinctiveness are improved, but difficulty of detecting and measuring unique characteristics increases
Solution Approach 1:
The patent applies color changes by developing a Hosta cultivar with distinctive variegated leaf patterns featuring blue-green margins and gold centers. The color differentiation between margin and center regions creates visual distinctiveness while the specific color combination (blue-green and gold) provides measurable characteristics for identification and breeding purposes.
2Volume of moving object
If larger plant size and leaf dimensions are achieved, then visual impact and aesthetic value are improved, but resource requirements and cultivation difficulty increase
Solution Approach 1:
The patent applies parameter changes by selecting and propagating plants with specific genetic variations that result in larger plant size and leaf dimensions. Through tissue culture propagation and selective breeding, the cultivar maintains enlarged physical parameters (height 45-55 cm, width 50-60 cm, leaf size 30-35 cm long) while managing cultivation requirements through controlled propagation methods.
3Reliability
If stable asexual reproduction is maintained, then reliability and consistency of cultivar characteristics are improved, but genetic diversity and adaptability may be reduced
Solution Approach 1:
The patent applies copying through tissue culture propagation methods that create genetically identical copies of the selected sport mutant. This ensures reliable reproduction of the unique variegated characteristics while maintaining genetic consistency across multiple plants. The copying process through division and tissue culture preserves the distinctive blue-green margin and gold center pattern in successive generations.
