Gerbera UFGE 4141 Breeding for Mildew Resistance and Peduncle Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Gerbera plant cultivars lack a combination of desirable traits such as medium peduncle length, semi-double orange-red inflorescences, and effective resistance to powdery mildew, particularly for use in large containers under varying environmental conditions.
Innovation Solution
The development of the new Gerbera hybrida variety 'UFGE 4141' with medium peduncle length, semi-double orange-red inflorescences, and moderate resistance to powdery mildew, achieved through a breeding program combining 'UFGE 5-23' and 'UFGE 4-8', and propagated via crown division and tissue culture, retaining characteristics across multiple generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current Gerbera plant cultivars are used, then they have existing characteristics, but they lack a combination of medium peduncle length, semi-double orange-red inflorescences, and effective resistance to powdery mildew
Solution Approach 1:
The patent combines multiple desirable traits (medium peduncle length of 52 cm, semi-double inflorescence type, orange-red ray florets, and powdery mildew resistance) into a single Gerbera cultivar through controlled breeding programs, merging characteristics that were previously分散 in different cultivars
2Ease of operation
If Gerbera plants are grown in large containers (≥20-cm in diameter), then they can produce attractive plants, but maintaining consistent characteristics across generations is challenging
Solution Approach 1:
The patent establishes stable遗传 characteristics through preliminary breeding and selection processes before commercial propagation, ensuring that the cultivar maintains consistent traits (peduncle length, inflorescence type, color, disease resistance) across multiple generations when propagated by crown division or tissue culture

AI summary
A new Gerbera plant particularly distinguished by having a novel combination of medium lengths of peduncles, semi-double orange-red inflorescence color, a moderate level of resistance to powdery mildew, and demonstrated potential to produce attractive plants in large (≧20-cm in diameter) containers, is disclosed.
