Pacshorg Geranium Cultivar Stable Semi-Double Orange Flowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Zonal Geranium cultivars lack uniform semi-double flowered varieties with dark green leaves and attractive flower coloration, and they often exhibit variability in growth and flower characteristics under different environmental conditions.
Innovation Solution
A new cultivar, 'PACSHORG' (Pelargonium×hortorum), developed through planned breeding, exhibits a compact, upright growth habit, dark green leaves, and semi-double bright orange flowers, with stable reproduction through vegetative terminal cuttings, offering improved vigor and flower color compared to parent selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Zonal Geranium cultivars are grown under different environmental conditions, then growth and flower characteristics vary, but this leads to inconsistency in plant performance and appearance
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific genetic parameters through controlled cross-pollination and selective breeding. The inventor crossed two unnamed proprietary selections and selected a single flowering plant from the progeny that exhibited desirable stable characteristics, thereby changing the genetic parameters to achieve environmental consistency.
2Manufacturing precision
If uniform semi-double flowered varieties are developed, then flower uniformity and coloration are improved, but breeding complexity and time investment increase
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination between selected parent plants before mass production. The inventor performed the cross-pollination in advance, grew the progeny in a controlled greenhouse environment, and selected the best individual plant before asexual reproduction, thereby ensuring uniformity before commercial propagation.
Solution Approach 2:
The patent applies copying by using asexual reproduction through vegetative terminal cuttings to create identical copies of the selected parent plant. This ensures that all commercial plants are genetic clones with uniform semi-double flower form and coloration, eliminating variability while simplifying subsequent production.
3Shape
If dark green leaves and attractive flower coloration are selected, then aesthetic value is improved, but selection criteria and breeding difficulty increase
Solution Approach 1:
The patent applies local quality by focusing on specific local characteristics of the plant - specifically the dark green coloration of leaves and the attractive coloration of flowers. The inventor selected the single flowering plant from progeny based on these specific local qualities rather than overall plant performance, simplifying the selection process.
