Chrysanthemum CIDZ0101 Cultivar Hybridization and Trait Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Chrysanthemum cultivar with specific characteristics such as medium-sized butterscotch bronze daisy-type inflorescences, broad and strong plant habit, and a 7.5-week flowering response time, which are not met by existing varieties like 'Yoauburn'.
Innovation Solution
The development of Chrysanthemum x morifolium cultivar 'CIDZ0101' through hybridization of 'B7017' and 'B7967', characterized by its unique inflorescence color, plant habit, and flowering response, which is fixed through asexual reproduction and retains its traits across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Chrysanthemum varieties are used, then breeding program requirements are met, but the specific characteristics (medium-sized butterscotch bronze inflorescences, broad plant habit, 7.5-week flowering response) cannot be achieved
Solution Approach 1:
The patent combines specific traits from two parent lines ('B7017' and 'B7967') through controlled hybridization to create a new cultivar with the desired medium-sized butterscotch bronze inflorescences, broad plant habit, and 7.5-week flowering response time, achieving a unique combination of characteristics not present in either parent alone
Solution Approach 2:
The patent achieves the target flowering response time of 7.5 weeks and specific inflorescence characteristics by selecting and combining parental lines with complementary traits, then stabilizing these parameters through asexual reproduction to ensure consistent expression across generations
2Reliability
If asexual reproduction is used to fix traits, then trait consistency is achieved, but genetic diversity is reduced
Solution Approach 1:
The patent performs the genetic combination and trait stabilization through asexual reproduction in advance, creating a genetically uniform population that consistently expresses the desired traits (medium-sized butterscotch bronze inflorescences, broad plant habit, 7.5-week flowering response) without the need for further genetic variation in subsequent propagation
