Compact Orange Rose Plant with Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rose cultivars lack uniform and abundant orange flowers, vigorous yet compact growth, and exceptional disease resistance, which are desired qualities for a new and distinct rose variety.
Innovation Solution
A new rose variety, 'Poulpal094', is developed through controlled crossing of unnamed seedling parents, resulting in a rose with orange flowers, compact growth height of 30-55 cm, and exceptional disease resistance, achieved through asexual reproduction and propagation in controlled environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing rose cultivars are used, then they have established growth patterns, but they lack uniform and abundant orange flowers, vigorous yet compact growth, and exceptional disease resistance
Solution Approach 1:
The patent applies parameter changes by creating a new rose variety with specific genetic parameters that differ from existing cultivars. The hybridization process combines parental traits to achieve new parameter combinations: orange flower color (distinct from parent colors of near-white and red), compact growth height (30-55 cm versus 25 cm in one parent), and enhanced disease resistance. This resolves the contradiction by establishing new parameter values that simultaneously achieve uniform abundant orange flowers and exceptional disease resistance.
2Strength
If rose varieties are developed for vigorous growth, then they show strong vitality, but they may become less compact
Solution Approach 1:
The patent applies local quality by achieving vigorous growth (strong vitality) while maintaining compact dimensions (30-55 cm height) through selective breeding. The new variety exhibits localized characteristics: robust root system and overall plant vitality combined with controlled above-ground growth. This resolves the contradiction by allowing the plant to be vigorous in terms of health and productivity while maintaining a compact form suitable for specific market preferences.
