Kinlar Lettuce Variety for Disease Resistance and Yield Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved lettuce varieties that are stable, high yielding, and agronomically sound to meet the increasing global demand for lettuce.
Innovation Solution
Development of a new lettuce variety designated 'kinlar' with specific traits such as resistance to diseases, pests, and tolerance to environmental stresses, achieved through selective breeding and genetic modification, including resistance to lettuce mosaic virus, downy mildew, corky root, and fusarium wilt, and tolerance to heat and cold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lettuce varieties are cultivated, then they can be grown in various environments, but they show susceptibility to diseases and pests leading to reduced yields
Solution Approach 1:
The patent applies parameter changes by developing lettuce varieties with modified genetic parameters that confer resistance to specific diseases and pests. The breeding process alters the biological parameters of the lettuce plants to include resistance traits while maintaining agronomic performance, thereby resolving the contradiction between reliability and productivity.
2Reliability
If lettuce varieties are bred for disease resistance, then reliability improves, but breeding complexity and time increase
Solution Approach 1:
The patent employs preliminary action by pre-selecting parental lines with known disease resistance traits and using targeted breeding approaches. The breeding program incorporates preliminary characterization of resistance genes and planned crossing strategies, which reduces the overall complexity and time required to develop resistant varieties compared to traditional random breeding methods.
3Productivity
If new lettuce varieties are developed to meet increasing demand, then productivity increases, but stability and agronomic soundness may be compromised
Solution Approach 1:
The patent implements feedback mechanisms through multi-location and multi-year trials to evaluate the stability of new lettuce varieties. The breeding program incorporates feedback from performance data to refine selection criteria and ensure that high-yielding varieties maintain stability across different environments. This systematic feedback approach resolves the contradiction between increasing productivity and maintaining variety stability.
