Petunia USTUNI60-01M White Red-Purple Venation Mutation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a distinct cultivar of Petunia×hybrida that exhibits unique characteristics such as upright and spreading growth habit, vigorous branching, and specific flower coloration, which are not met by existing cultivars like 'USTUNI6001' and 'Kakegawa S37', particularly in terms of flower color and vigor.
Innovation Solution
The new cultivar 'USTUNI60–01M' is a naturally occurring branch mutation of Petunia×hybrida 'USTUNI6001' with stable asexual reproduction by vegetative cuttings, characterized by white flowers with red-purple venation, and enhanced vigor compared to 'Kakegawa S37', offering improved garden performance and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing cultivars like 'USTUNI6001' and 'Kakegawa S37' are used, then established growth habits and flowering are achieved, but unique flower coloration and enhanced vigor are not obtained
Solution Approach 1:
The patent applies parameter changes by selecting for a natural mutation that alters flower color parameters (from pink to white with red-purple venation) while maintaining other cultural characteristics. This allows the new cultivar to distinguish itself visually while preserving adaptability to standard growing conditions
2Quantity of substance
If a new distinct cultivar with unique characteristics is developed, then flower color and vigor are improved, but stability of reproduction must be ensured
Solution Approach 1:
The patent employs self-service through natural mutation and selection, where the plant itself provides the genetic variation through spontaneous mutation. The mutation was discovered in a natural population and selected for its unique characteristics, allowing the cultivar to maintain genetic stability through true-to-type vegetative reproduction without requiring complex genetic engineering
