Calibrachoa Wescasto Breeding for Trait Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Calibrachoa cultivars lack uniform plant habit and attractive flower characteristics, with variations in growth habit, flower size, and color, which are not consistently reproduced across different environmental conditions.
Innovation Solution
The development of the new Calibrachoa cultivar 'Wescasto' through planned breeding, combining traits such as mounding and spreading growth habit, vigorous growth, medium-sized leaves, and numerous star-shaped dark orange and yellow flowers, achieved through cross-pollination of proprietary seedling selections, which are stable and true to type in successive generations via vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Calibrachoa cultivars are grown under varying environmental conditions, then growth habit and flower characteristics vary, but this leads to inconsistent reproduction of desired traits
Solution Approach 1:
The patent applies parameter changes by selecting and fixing specific genetic parameters through controlled cross-pollination. The breeding program deliberately selected parent plants with complementary traits (female parent with compact habit, male parent with vigorous growth) and fixed the resulting trait combination in the hybrid cultivar, making the traits stable across environmental variations.
Solution Approach 2:
The patent employs preliminary action through extensive pre-breeding work and selection before releasing the cultivar. The Inventor conducted multiple seasons of selection and evaluation, pre-testing the hybrid under various conditions to ensure trait stability before commercial release. This preliminary validation ensured the cultivar would maintain consistent traits in commercial production.
2Stability of the object's composition
If Calibrachoa cultivars are bred for uniform growth habit, then plant habit becomes consistent, but flower attractiveness and variety may be reduced
Solution Approach 1:
The patent merges previously separate selection criteria by combining uniform growth habit selection with flower quality selection in a single hybrid cultivar. The cross-pollination between selected parent plants merged the compact habit trait from the female parent with the vigorous growth and attractive flower traits from the male parent, achieving both uniformity and aesthetic quality simultaneously.
3Area of moving object
If Calibrachoa cultivars are bred for larger flowers, then flower size increases, but lateral branch length and overall plant vigor may be reduced
Solution Approach 1:
The patent applies local quality by allowing different parts of the plant to express different characteristics optimized for their function. The hybrid cultivar exhibits larger flowers (local optimization for reproduction) while maintaining vigorous lateral branching (local optimization for growth and spread). This is achieved through the complementary genetic contributions from parent plants selected for specific local traits.
