Delosperma Dodelsolpi Cultivar Breeding for Consistent Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new early-flowering Delosperma plants with attractive flowers that can thrive under various environmental conditions and cultural practices, as existing cultivars may not consistently exhibit desired traits across different settings.
Innovation Solution
A new cultivar, 'Dodelsolpi', was developed through self-pollination of a proprietary selection of Delosperma cooperi, characterized by an upright and spreading habit, rapid growth, dense branching, and large red-purple flowers with yellow and white centers, which is stable across generations and exhibits improved garden performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Delosperma cultivars are used, then they may exhibit certain flower colors and growth habits, but they do not consistently display desired traits across different environmental conditions and cultural practices
Solution Approach 1:
The patent develops a new cultivar 'Dodelsolpi' through controlled breeding that modifies genetic parameters to achieve stable expression of desired traits (upright growth habit, early flowering, flower color) across varying environmental conditions. The self-pollination breeding program selected plants with enhanced genetic stability and adaptability, resulting in consistent phenotype expression regardless of temperature or light intensity variations.
2Productivity
If Delosperma plants are bred for early flowering and numerous attractive flowers, then flower production is improved, but growth habit and stability across generations may be compromised
Solution Approach 1:
The breeding program conducted preliminary selection and self-pollination of parent plants before mass propagation. Multiple generations were screened for stable inheritance of desired traits (upright growth, early flowering, flower color) before establishing the final cultivar. This preliminary action ensured that only genetically stable lines with high flower production capability were selected for the 'Dodelsolpi' cultivar.
Solution Approach 2:
The cultivar utilizes self-pollination for reproduction, which maintains genetic stability and ensures consistent trait expression across generations. The plant's self-service reproductive mechanism preserves the selected characteristics without requiring external pollination, thereby guaranteeing trait stability while maintaining high flower production.
3Shape
If Delosperma plants are selected for upright and spreading growth habit, then groundcover performance is improved, but flowering frequency and flower size may be reduced
Solution Approach 1:
The cultivar exhibits local quality differentiation where different parts of the plant optimize for different functions: the growth habit (upright and spreading) optimizes for groundcover performance and light capture, while the flowering structures (numerous flowers with vibrant colors) optimize for reproduction. This spatial and functional differentiation allows the plant to simultaneously achieve desirable growth form and high flowering frequency without compromise.
