Lobelia Wespurstar Cultivar Compact Habit and Purple Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Lobelia cultivars with improved vigor and attractive flower coloration that can reproduce stably and consistently under varying environmental conditions.
Innovation Solution
The development of the 'Wespurstar' Lobelia cultivar, resulting from a cross-pollination between Lobelia erinus 'Wespinstar' and a proprietary seedling selection, which exhibits a compact, spherical, and trailing plant habit with intense purple flowers, vigorous growth, and continuous flowering, distinguishing it from parent cultivars and other varieties like 'Hot Lilac'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cross-pollination breeding program is conducted to create new Lobelia cultivars, then new cultivars with good vigor and attractive flower coloration can be developed, but the breeding process requires significant time and resources
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination between specifically selected parent plants ('Wespinstar' female parent and code 04P721 male parent) before the breeding program begins. The parent plants were pre-selected for desirable traits including vigor and flower coloration, which accelerates the development of reliable new cultivars with consistent characteristics.
2Stability of the object's composition
If terminal cuttings are used for asexual reproduction, then the unique features of the cultivar can be stably reproduced, but the propagation process requires controlled environmental conditions
Solution Approach 1:
The patent applies copying by using terminal cuttings to create genetically identical copies of the parent plant. This asexual reproduction method ensures that the unique features of the 'Wespurstar' cultivar are stably reproduced in successive generations, maintaining trait consistency without requiring complex controlled environments for each propagation cycle.
3Shape
If the cultivar is designed with compact, spherical plant habit and short internodes, then a dense and bushy plant form is achieved, but the plant size is reduced
Solution Approach 1:
The patent applies spheroidality by designing the cultivar with a compact, spherical plant habit. The short internodes and freely branching growth pattern create a dense, bushy, and rounded form that is highly desirable for container cultivation and ornamental applications, transforming the plant's natural growth into a compact spherical shape.
4Ease of manufacture
If the flowers are bred for intense purple coloration with larger upper petals, then flower attractiveness is improved, but the overall flower size may be reduced
Solution Approach 1:
The patent applies local quality by concentrating floral resources into specific areas: the upper petals are enlarged and intensely colored in purple, while the overall flower size remains compact. This localized enhancement of petal quality and coloration creates highly attractive flowers without increasing the total flower diameter, optimizing both visual impact and plant compactness.
