Calibrachoa Cultivar PAS1020344 Dark Violet Flower Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Calibrachoa cultivars lack unique flower coloration and mounded-trailing growth habits, leading to a need for new varieties that combine distinct flower colors and specific growth characteristics.
Innovation Solution
Development of the Calibrachoa×hybrida cultivar 'PAS1020344' through controlled cross-pollination between proprietary breeding selections N1112R and N8551R, resulting in dark violet-colored flowers and a moderately vigorous, mounded-trailing growth habit, which can be reproduced both sexually and asexually.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If controlled cross-pollination is used to develop new Calibrachoa cultivars, then unique flower coloration and mounded-trailing growth habit are achieved, but breeding program complexity and time required increase
Solution Approach 1:
The patent applies preliminary action by pre-selecting parent plants with specific desirable traits (dark violet-blue flowers, compact-mounded growth habit) before cross-pollination. The parent selections N1112R and N8551R were specifically chosen for their homozygosity and uniform phenotypes, ensuring that the breeding program would efficiently produce uniform offspring with the desired mounded-trailing growth habit and dark violet flower coloration, thereby reducing the overall complexity and time of the breeding program.
2Stability of the object's composition
If phenotypically uniform progeny are produced through selective cross-pollination, then consistency in flower color and growth habit is achieved, but genetic diversity is reduced
Solution Approach 1:
The patent applies parameter changes by focusing on specific genetic parameters (flower color, growth habit) while maintaining homozygosity in the parent lines. By selecting parents with fixed phenotypic characteristics and controlled homozygosity, the breeding program achieves stable phenotypic uniformity in the offspring for the desired traits (dark violet flowers, mounded-trailing habit) while the controlled nature of the cross-pollination allows for targeted genetic manipulation rather than random variation.
3Reliability
If asexual reproduction by terminal stem cuttings is used, then true-to-type propagation is achieved, but propagation time and labor requirements increase
Solution Approach 1:
The patent applies copying by using terminal stem cuttings to create exact genetic replicas of the parent plants. This asexual propagation method produces offspring that are true-to-type, preserving the unique dark violet flower coloration and mounded-trailing growth habit with 100% fidelity. The cutting process involves taking terminal stems, allowing them to root, and transplanting, which creates identical copies of the desired genotype and phenotype.
