Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a Stevia cultivar that exhibits a compact growth habit, vigorous growth, high cold temperature tolerance, and high concentration of steviol glycosides, which are stable and true to type across varying environmental conditions.
Innovation Solution
The cultivar 'LOSTE1517' is developed through controlled cross-pollination and asexual propagation, characterized by compact growth, vigorous branching, and high steviol glycoside content, maintaining stability across different environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a Stevia cultivar is selected for compact growth habit, then plant size is reduced, but productivity may be limited due to smaller biomass
Solution Approach 1:
The cultivar LOSTE1517 represents a parameter change in plant architecture, achieving compact growth through controlled breeding that maintains vigorous branching and high steviol glycoside concentration, thus preserving productivity within a smaller volume
2Productivity
If a Stevia cultivar is selected for vigorous growth and free branching, then biomass production increases, but plant size becomes larger and less compact
Solution Approach 1:
LOSTE1517 achieves a parameter optimization where vigorous growth and free branching are maintained while the overall plant architecture remains compact, resolving the contradiction between biomass production and plant size through selective breeding
3Adaptability or versatility
If a Stevia cultivar is selected for high cold temperature tolerance, then adaptability to cold environments is improved, but growth vigor may be reduced
Solution Approach 1:
The cultivar LOSTE1517 exhibits a parameter change in physiological tolerance, achieving high cold temperature tolerance while maintaining vigorous growth and free branching characteristics, thus resolving the trade-off between adaptability and productivity
4Quantity of substance
If a Stevia cultivar is selected for high concentration of steviol glycosides, then product quality is improved, but growth rate may be reduced due to resource allocation
Solution Approach 1:
LOSTE1517 demonstrates a parameter optimization where high steviol glycoside concentration is achieved alongside vigorous growth and moderate growth rate, balancing secondary metabolite production with primary growth through selective breeding
5Adaptability or versatility
If a Stevia cultivar is propagated through controlled cross-pollination, then genetic diversity is improved, but breeding time and complexity increase
Solution Approach 1:
The cultivar LOSTE1517 was developed through preliminary controlled cross-pollination between selected parents, establishing the desired traits in the F1 generation, which then were stabilized through asexual propagation, reducing the time required for further breeding
6Stability of the object's composition
If a Stevia cultivar is propagated asexually through softwood cuttings, then genetic stability is improved, but propagation time and labor increase
Solution Approach 1:
The cultivar LOSTE1517 was preliminarily selected and characterized through controlled cross-pollination, then propagated asexually through softwood cuttings to establish genetic stability and true-to-type characteristics, optimizing the balance between genetic stability and propagation efficiency
