Dianthus Raspberry Ruffles Cross-Breeding for Double Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Dianthus that combines unique floral characteristics such as fully-double flowers with a specific petal count, coloration, and fragrance, which are not present in existing cultivars like 'WP Passion' and 'Fancy Knickers', and also exhibits resistance to environmental variations and disease.
Innovation Solution
The development of the Dianthus 'Raspberry Ruffles' cultivar, resulting from a cross between 'WP Passion' and 'Fancy Knickers', which features fully-double flowers with 105 petals, raspberry-colored petals with a light pink to white margin, irregularly toothed petal edges, a spicy fragrance, and compact growth habit, along with disease resistance and adaptability to varying environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional Dianthus cultivars like 'WP Passion' or 'Fancy Knickers' are used, then the plants have simpler flower structures with fewer petals, but they lack the fully-double flower form with high petal count desired in the new cultivar
Solution Approach 1:
The patent combines traits from two parent cultivars ('WP Passion' and 'Fancy Knickers') through controlled cross-breeding to produce a hybrid with fully-double flowers containing approximately 105 petals, merging the desirable characteristics of both parents to achieve high petal count while maintaining plant viability
2Ease of manufacture
If the new cultivar 'Raspberry Ruffles' is developed with unique coloration and petal characteristics, then it provides distinctive ornamental value, but it requires precise control over multiple floral traits simultaneously
Solution Approach 1:
The patent specifies particular local characteristics including raspberry-colored petals with lighter margins, irregularly toothed petal edges, and fully-double flower form, allowing selective emphasis on specific floral traits while maintaining overall plant health and vigor
3Reliability
If the cultivar is bred for specific fragrance and color traits, then ornamental and aromatic value is enhanced, but the plant may become more sensitive to environmental variations
Solution Approach 1:
The patent describes a cultivar that maintains consistent fragrance intensity and color expression across varying environmental conditions, achieving reliability in trait expression while adapting to different growing environments through selective breeding for environmental resilience
