Sunlorose Asarina Cultivar Trailing Habit and Branching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new trailing and freely branching Asarina plants with attractive leaf and flower coloration that can reproduce stably and maintain their unique features across varying environmental conditions.
Innovation Solution
The development of a new Asarina hybrid cultivar, 'Sunlorose', resulting from a cross-pollination between proprietary selections LP133-1 and LP115-1, which exhibits a trailing habit, vigorous growth, freely branching, long flowering period, and small vivid red-purple flowers, and has been reproduced via vegetative cuttings to ensure stability of its characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cross-pollination breeding is conducted to create new Asarina hybrids with attractive coloration, then flower and leaf coloration is improved, but genetic stability and true-to-type reproduction may deteriorate
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination between specifically selected parent plants (LP133-1 and LP115-1) with desired traits before stabilization. The breeding program pre-establishes the genetic combination that will produce the 'Sunlorose' cultivar with its distinctive red-purple flowers and green foliage, ensuring the desired coloration is achieved before propagation
Solution Approach 2:
The patent applies parameter changes by modifying the genetic parameters through controlled cross-pollination to achieve the specific phenotype of 'Sunlorose'. The breeding process changes the genetic composition parameters to produce plants with vibrant red-purple flower coloration and green foliage, which are then stabilized through vegetative propagation
2Stability of the object's composition
If vegetative cuttings are used for asexual reproduction, then genetic stability and true-to-type reproduction are improved, but genetic diversity and new trait development may deteriorate
Solution Approach 1:
The patent applies copying by using vegetative cuttings to asexually reproduce the 'Sunlorose' cultivar. This copying method creates genetically identical replicas of the parent plant, ensuring that the distinctive red-purple flower coloration, green foliage, and trailing growth habit are perfectly replicated across multiple plants without genetic variation
Solution Approach 2:
The patent applies segmentation by taking cuttings from specific segments (stems or branches) of the parent plant to propagate new individuals. This segmentation approach allows for efficient multiplication of the cultivar while maintaining genetic fidelity, as each cutting develops into a complete plant with the same characteristics
3Ease of manufacture
If trailing and freely branching growth habits are selected, then ornamental value and garden performance are improved, but plant control and management difficulty may worsen
Solution Approach 1:
The patent applies local quality by developing a cultivar with differentiated growth characteristics in different parts of the plant. The 'Sunlorose' exhibits trailing stems that spread horizontally while maintaining freely branching lateral growth, creating a structured yet natural appearance that is well-suited for hanging baskets and containers where the trailing habit is advantageous
