Salvia ‘DH004’ Selective Breeding for Violet-Blue Flowers and Compact Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of Salvia plant that exhibits violet blue flowers, large leaf size, and a compact, low-growing habit, which are not adequately addressed by existing Salvia varieties.
Innovation Solution
The development of a new Salvia variety, 'DH004', derived from a cross between '1431-6-T2' and 'Calamity Jane', characterized by violet blue flowers, large leaves, and a compact growth habit, suitable for home gardens, commercial landscapes, and water-wise gardens, with specific cultural requirements and hardiness in zone 8a.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Salvia varieties are used, then general ornamental value is maintained, but violet blue flower color and large leaf size are not achieved
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific traits including flower color (violet blue), leaf size (large), and growth habit (compact). This resolves the contradiction by creating a new variety that meets specific aesthetic parameters while maintaining adaptability through controlled propagation methods.
2Shape
If Salvia varieties with vibrant flowers are selected, then ornamental value is improved, but plant size becomes too large for compact spaces
Solution Approach 1:
The patent applies local quality by concentrating desirable traits (violet blue flowers, large leaves) in specific areas while controlling overall plant dimensions. The compact growth habit is achieved through selective breeding that promotes dense, low-growing architecture, resolving the contradiction between vibrant floral display and compact size suitable for containers and small spaces.
3Productivity
If traditional propagation methods are used, then plant multiplication is achieved, but true-to-type reproduction consistency varies
Solution Approach 1:
The patent applies self-service through the use of tissue culture propagation, where the plant cells themselves are induced to multiply and differentiate into complete plants. This method ensures true-to-type reproduction because each new plant is genetically identical to the parent, resolving the contradiction between propagation efficiency and reproduction consistency.
