Dasiphora ‘Bailpine’ Breeding for Compact Form and Golden Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cultivars of Dasiphora fruiticosa lack unique flower colors and compact, mounded forms, limiting their aesthetic appeal and landscape use.
Innovation Solution
Development of a new cultivar, 'Bailpine', featuring double bright golden yellow flowers and a compact, mounded form with tinted blue-green foliage, achieved through controlled breeding and asexual propagation by softwood cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing cultivars of Dasiphora fruiticosa are used, then the plant is easy to grow and maintain, but the flower color is not unique and the plant form is not compact
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific phenotypic parameters (double flowers, bright golden yellow color, compact mounded form) to create a new cultivar that differs from existing varieties in shape and flower characteristics
2Illumination intensity
If existing cultivars of Dasiphora fruiticosa are used, then the plant is easy to propagate, but the flower color lacks uniqueness and aesthetic appeal
Solution Approach 1:
The patent applies preliminary action by conducting a controlled breeding program starting in 2000, systematically cross-pollinating and selecting plants with desired traits (double flowers, unique colors) before the target cultivar is finalized, thereby preparing the genetic foundation in advance
3Adaptability or versatility
If new cultivars with unique traits are developed through controlled breeding, then unique flower colors and compact forms are achieved, but the breeding program is complex and time-consuming
Solution Approach 1:
The patent applies local quality by focusing the breeding program on specific localized traits (double flower structure, bright golden yellow color, compact mounded shape) rather than attempting to change all plant characteristics, thereby simplifying the breeding objectives while achieving unique aesthetic qualities
