New Guinea Impatiens SAKIMP038 Hybridization for Variegation Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of New Guinea impatiens that exhibits bright flower color, clear variegation, and a strong root system, which existing varieties fail to consistently provide under different environmental conditions.
Innovation Solution
The development of the Impatiens×hybrida hort variety 'SAKIMP038' through hybridization of proprietary lines 'NG-02SM-13' and 'NF-457BB', which is characterized by orange-red flowers and green leaves with yellow variegation, and is stable across generations through vegetative propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Impatiens varieties are grown under different environmental conditions, then their flower color and leaf variegation may be inconsistent, but this patent achieves consistent bright flower color and clear variegation through hybridization
Solution Approach 1:
The patent applies parameter changes by selecting specific parental lines with complementary traits and controlling hybridization parameters to produce F1 plants with stable, consistent flower color and leaf variegation that reliably express these traits across different environmental conditions
2Stability of the object's composition
If a single plant selection is made from F1 population, then trait stability can be achieved, but genetic diversity is reduced
Solution Approach 1:
The patent uses vegetative propagation (copying) of the selected F1 plant to produce multiple identical clones that all express the desired traits stably, avoiding the genetic segregation that would occur with sexual reproduction while maintaining trait consistency across the entire population
