Te Jiao Rose Cultivar Breeding for Continuous Blooming and Minimal Seed Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rose cultivars struggle to maintain continuous blooming during hot summers and produce excessive seeds, which limits their performance in northern China's climate.
Innovation Solution
The development of a new climbing rose cultivar, 'Te Jiao', bred from 'Dortmund' and 'Beilinhong', exhibiting semi-double pink flowers, continuous blooming from April to November, minimal seed production, semi-glossy foliage, upright growth habit, vigorous growth, and good disease resistance, achieved through controlled breeding and asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If existing rose cultivars are grown in northern China during hot summers, then they can provide ornamental value through flowering, but they fail to maintain continuous blooming and produce excessive seeds
Solution Approach 1:
The patent applies parameter changes by selectively breeding roses with modified genetic parameters that alter flowering behavior and seed production. The cultivar 'Te Jiao' exhibits changed parameters including extended blooming duration from April to November and reduced seed production, achieved through controlled breeding programs that selected for these specific traits.
2Duration of action of stationary object
If rose cultivars are bred for continuous blooming in hot summers, then blooming duration is improved, but disease resistance may be compromised
Solution Approach 1:
The patent achieves multi-functionality by breeding a rose cultivar that simultaneously provides extended blooming duration and strong disease resistance. The cultivar 'Te Jiao' combines multiple desirable traits including continuous flowering from April to November, resistance to common rose diseases, and adaptability to hot summer conditions, making it a universal solution for northern China landscaping.
3Quantity of substance
If rose cultivars produce abundant seeds, then genetic diversity is maintained, but ornamental performance and landscaping utility are reduced
Solution Approach 1:
The patent applies the extraction principle by removing the unwanted characteristic of excessive seed production from the rose cultivar. The breeding program specifically selected against high seed production, extracting this trait from the population to create cultivars like 'Te Jiao' that produce minimal seeds, thereby improving landscaping maintenance and ornamental performance.
