Phlox Cherry Cream Cultivar Breeding for Mildew Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Phlox cultivars lack sufficient powdery mildew resistance and compact growth habit, which are desirable traits for horticultural applications.
Innovation Solution
A new cultivar, 'Cherry Cream', derived from open-pollination, exhibiting dark reddish-purple and white bicolored flowers, medium green foliage, and a moderately vigorous, upright growth habit, with improved resistance to powdery mildew and a more compact growth habit compared to its parent 'Laura'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Phlox cultivars are used, then they have vigorous growth habit, but they lack powdery mildew resistance and compact growth habit
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic traits that alter their physiological parameters. The 'Cherry Cream' cultivar was developed through open-pollination and selected for specific characteristics including compact growth habit and improved powdery mildew resistance, representing a change in the genetic parameters of the Phlox plant to achieve disease resistance while maintaining desirable growth characteristics.
2Shape
If existing Phlox cultivars are used, then they have upright growth habit, but they lack compact growth habit
Solution Approach 1:
The patent achieves compact growth habit through parameter changes in the plant's physical dimensions. The 'Cherry Cream' cultivar exhibits a compact growth habit with reduced plant height and smaller overall size compared to traditional upright Phlox cultivars, while maintaining an upright growth form. This represents a deliberate modification of the plant's morphological parameters to create a more compact variety suitable for specific horticultural applications.
