Fusarium-Resistant Lettuce Variety for Stable Continuous Cropping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lettuce plants face poor growth and diseases such as Fusarium wilt due to continuous cropping and unusual weather conditions, necessitating the development of stable lettuce varieties.
Innovation Solution
A novel lettuce plant designated as TEXLE213131, identified by Accession No. FERM BP-22497, exhibits high resistance to Fusarium oxysporum f. sp. Lactucae races, including Fol Race 1 and Yuma isolate, and is characterized by specific morphological and physiological traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous cropping is practiced to maintain production, then productivity is improved, but disease resistance deteriorates due to Fusarium wilt accumulation
Solution Approach 1:
The patent applies parameter changes by developing a new lettuce variety (TEXLE213131) with altered genetic parameters that confer resistance to Fusarium oxysporum f. sp. Lactucae. This variety possesses specific physiological and morphological characteristics that enable it to withstand continuous cropping conditions without succumbing to Fusarium wilt, thereby resolving the contradiction between maintaining productivity through continuous cropping and preserving disease resistance.
2Stability of the object's composition
If high temperature and high humidity conditions occur due to unusual weather, then growth stability deteriorates, but disease susceptibility improves
Solution Approach 1:
The patent utilizes parameter changes by creating a lettuce variety adapted to high temperature and high humidity conditions. The variety TEXLE213131 exhibits modified physiological parameters including heat tolerance and humidity adaptation, which enable stable growth under unusual weather conditions while simultaneously maintaining resistance to Fusarium wilt, thus resolving the contradiction between growth stability and disease susceptibility under stress conditions.
