Bi-Colored Impatiens Cultivar Breeding for Early Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing New Guinea Impatiens cultivars lack desirable traits such as early and frequent flowering, vigorous growth, and attractive bi-colored flowers, which limits their garden performance and aesthetic appeal.
Innovation Solution
A new cultivar, 'Dongipetorsta 21', resulting from a controlled cross-pollination of proprietary Impatiens hawkeri selections, exhibits upright to spreading growth, dark green leaves, and medium-sized orangish red and pale purplish pink bi-colored flowers, offering improved branching, flowering habit, and garden performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing New Guinea Impatiens cultivars are used, then they have basic growth and flowering, but they lack early and frequent flowering, vigorous growth, and attractive bi-colored flowers
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic traits that modify flowering time, flower coloration, and growth vigor. The cross-pollination between parent plants with different characteristics produced offspring with improved parameters including earlier flowering, bi-colored flowers, and vigorous growth, directly resolving the contradiction between productivity and reliability.
2Ease of manufacture
If existing cultivars are used, then they have simple flower colors, but they lack attractive bi-colored flowers with specific color patterns
Solution Approach 1:
The patent merges traits from two different parent plants through controlled cross-pollination. The female parent (NN14-516311-006) contributed growth habits and flowering characteristics, while the male parent (NN12-002628-003) contributed flower color genes. This combining of parental traits produced the bi-colored flower phenotype with orangish red and pale purplish pink coloring, achieving aesthetic appeal through genetic merging.
3Adaptability or versatility
If existing cultivars are used, then they have limited growth habits, but they lack upright to outwardly spreading and mounding habits with free branching
Solution Approach 1:
The patent achieves local quality by developing different growth habits in different parts of the plant. The plant exhibits upright central growth with outwardly spreading and mounding lateral branches, creating varied local structures. The freely branching habit allows different sections of the plant to have different orientations and growth patterns, providing adaptability while maintaining genetic stability through asexual reproduction.
