Cotinus SMNCCPP3 Plant Breeding and Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Cotinus plants with strong branches and attractive plant form and flower coloration that can reproduce true to type and perform well in various environmental conditions.
Innovation Solution
The development of a new Cotinus plant, 'SMNCCPP3', resulting from a breeding program using Cotinus coggygria 'Little Ruby' as the female parent and an unknown selection of Cotinus coggygria as the male parent, exhibiting an upright and spreading habit, dense branching, greyed purple to dark green leaves, and light greyed purple-colored inflorescences, which is stable through asexual reproduction by softwood stem cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a breeding program is conducted to create new Cotinus plants with strong branches and attractive plant form, then plant strength and form are improved, but the complexity of the breeding process increases
Solution Approach 1:
The breeding program utilizes open-pollination where the plant reproduces naturally without extensive人工 intervention. The new Cotinus plant 'SMNCCPP3' was obtained through open-pollination of Cotinus coggygria 'Little Ruby' during summer 2011, allowing the plant to self-service in the breeding process while still achieving the desired strong branches and attractive form
Solution Approach 2:
The invention propagates the new Cotinus plant through asexual reproduction by softwood stem cuttings, creating exact genetic copies that reproduce true to type. This copying method has been demonstrated since spring 2013 in a controlled environment, ensuring the unique features are stable and reproducible without repeating the complex breeding process
2Stability of the object's composition
If the new Cotinus plant is propagated through asexual reproduction by softwood stem cuttings, then genetic stability and true-to-type reproduction are achieved, but the time required for propagation increases
Solution Approach 1:
The invention performs preliminary action by taking softwood stem cuttings during the optimal spring window when the plant is actively growing but not yet fully mature. This timing allows the cuttings to root more efficiently, reducing the overall propagation time while maintaining genetic stability. The cuttings are prepared and planted in advance of the growing season to establish rooted plants before field conditions become unfavorable
3Shape
If the Cotinus plant is bred to have larger size compared to the female parent, then plant form and presence are improved, but the space requirement increases
Solution Approach 1:
The new Cotinus plant 'SMNCCPP3' exhibits local quality improvements with its upright and outwardly spreading habit that creates a dense, bushy appearance. The plant concentrates its growth in a compact, controlled form rather than spreading diffusively, achieving an attractive shrub-like form that maximizes visual impact while minimizing the actual space occupied compared to larger tree-like Cotinus varieties
