New Guinea Impatiens Breeding Line for Predictable Trait Development
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for developing new Guinea Impatiens varieties with novel characteristics such as color, growth habit, and hardiness, as existing propagation methods and breeding techniques are limited in predicting and achieving consistent genetic combinations.
Innovation Solution
The development of the New Guinea Impatiens variety SAKIMP076, which is produced through interspecific hybridization and vegetative propagation, and can be used in breeding programs to introduce mutations, edits, and combine desirable traits using methods like CRISPR/Cas9, TALENs, and backcrossing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional seed, cutting, or tissue culture propagation methods are used, then New Guinea Impatiens can be reproduced, but the genetic combinations are unpredictable and novel characteristics cannot be consistently achieved
Solution Approach 1:
The patent applies CRISPR/Cas9 genome editing technology to precisely modify specific genetic parameters in New Guinea Impatiens, enabling predictable changes in flower color, growth habit, and other characteristics while maintaining the ability to develop novel traits through targeted genetic parameter modification
2Productivity
If breeding programs use conventional crossing and selection methods, then new varieties can be developed, but the process is time-consuming and productivity is low
Solution Approach 1:
The patent replaces conventional mechanical breeding methods (crossing, selection) with molecular-level genome editing using CRISPR/Cas9, allowing direct modification of desired traits without requiring multiple generations of crossing and selection, thereby dramatically reducing breeding time and increasing productivity
3Reliability
If existing New Guinea Impatiens varieties are used, then ornamental value is maintained, but resistance to pests, diseases, and environmental tolerances are insufficient
Solution Approach 1:
The patent uses CRISPR/Cas9 to modify specific genetic parameters related to pest resistance, disease resistance, and environmental tolerance, enabling the development of New Guinea Impatiens varieties with enhanced reliability under various stress conditions while maintaining ornamental value

AI summary
A New Guinea Impatiens plant designated SAKIMP076 is disclosed. Embodiments include seeds of New Guinea Impatiens SAKIMP076, plants of New Guinea Impatiens SAKIMP076, to plant parts of New Guinea Impatiens SAKIMP076, and methods for producing an impatiens plant produced by crossing New Guinea Impatiens SAKIMP076 with itself or with another impatiens variety. Embodiments include methods for producing an impatiens plant containing in its genetic material one or more genes or transgenes and transgenic impatiens plants and plant parts produced by those methods. Embodiments also relate to impatiens varieties, breeding varieties, plant parts, and cells derived from New Guinea Impatiens SAKIMP076, methods for producing other impatiens lines or plant parts derived from New Guinea Impatiens SAKIMP076, and the impatiens plants, varieties, and their parts derived from use of those methods. Embodiments further include hybrid impatiens seeds, plants, and plant parts produced by crossing New Guinea Impatiens SAKIMP076 with another impatiens variety.
