Cytisus scoparius SMNCSCRY Compact Habit and Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Cytisus scoparius cultivars lack compact and uniform growth habits with attractive flower forms and colors, and there is a need for cultivars with improved density, flowering frequency, and flower size and color.
Innovation Solution
A new cultivar 'SMNCSCRY' of Cytisus scoparius, developed through open-pollination and stabilized via softwood stem cuttings, exhibits a compact and upright growth habit, dense and freely branching structure, and large bright yellow and red-colored flowers, differing from its parent and 'Madame Butterfly' in compactness and flower color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Cytisus scoparius cultivars are used, then the plant can be grown, but the growth habit is not compact and uniform, and flower form and color are not attractive
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific phenotypic parameters (compact growth habit, uniform structure, bright yellow and red flower colors) through controlled breeding and asexual reproduction. The cultivar 'SMNCSCRY' was developed by changing the phenotypic parameters of Cytisus scoparius through selective propagation to achieve the desired compactness and uniformity while maintaining attractive flower characteristics.
2Quantity of substance
If existing Cytisus scoparius cultivars are used, then the plant can be grown, but the density and flowering frequency are insufficient
Solution Approach 1:
The patent changes the quantitative parameters of the plant by developing a cultivar with increased density through selective breeding and stable propagation. The new cultivar 'SMNCSCRY' exhibits higher plant density and increased flowering frequency compared to existing cultivars, achieving both parameters simultaneously through controlled asexual reproduction that stabilizes these improved traits.
3Length of stationary object
If existing Cytisus scoparius cultivars are used, then the plant can be grown, but the flower size is small and color variation is limited
Solution Approach 1:
The patent applies parameter changes to increase flower size and expand color variation by selecting parent plants with desirable traits and stabilizing them through asexual reproduction. The new cultivar 'SMNCSCRY' produces larger flowers with bright yellow and red colors, demonstrating improved flower size and enhanced color variation compared to existing cultivars.
4Adaptability or versatility
If open-pollination is used to create new cultivars, then genetic diversity is increased, but the stability of unique features across generations is not guaranteed
Solution Approach 1:
The patent uses copying through asexual reproduction (softwood stem cuttings) to preserve and stabilize the unique features discovered during open-pollination. After identifying the desired traits in the open-pollination progeny, the inventor used softwood stem cuttings to create multiple copies of the selected plant, ensuring that the compact growth habit, uniform structure, and attractive flower characteristics are maintained stably across generations.
Solution Approach 2:
The patent combines parameter changes through selective breeding with stabilization through asexual reproduction. The open-pollination process introduced genetic diversity and created new phenotypic parameters, while subsequent asexual reproduction stabilized these parameters, ensuring that the unique features (compact habit, uniform structure, bright flowers) remain consistent across generations.
