Tecoma Sunhorteki Cultivar Breeding for Temperature Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Tecoma plant cultivars lack early and frequent flowering capabilities and low temperature tolerance, limiting their adaptability and performance under varying environmental conditions.
Innovation Solution
A new cultivar, 'Sunhorteki', resulting from a cross-pollination between proprietary selections of Tecoma hybrida, exhibits a semi-upright habit, vigorous growth, early and frequent flowering, bright yellow flowers, and low temperature tolerance, distinguishing it from parent and comparable cultivars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing Tecoma plant cultivars are used, then they have conventional flowering patterns, but they lack early and frequent flowering capabilities and low temperature tolerance
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific phenotypic parameters including early flowering time, frequent flowering cycles, bright yellow flower color, and low temperature tolerance. The new cultivar 'Sunhorteki' exhibits these modified parameters that distinguish it from conventional cultivars, enabling it to perform reliably under varying environmental conditions such as high temperatures and low temperatures.
2Productivity
If the new cultivar 'Sunhorteki' is developed with early and frequent flowering, then flowering performance is improved, but genetic stability must be maintained
Solution Approach 1:
The patent employs feedback mechanisms through controlled cross-pollination between selected parent plants (Horteco-1 and Horteco-2) and systematic evaluation of progeny. The breeding program continuously monitors flowering characteristics, flower color, and temperature tolerance, selecting only those plants that maintain genetic stability while exhibiting improved productivity. This feedback loop ensures that the new cultivar 'Sunhorteki' achieves high flowering frequency without compromising genetic consistency.
