Cultivated Rocket Variety With Downy Mildew Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of cultivated rocket (Eruca sativa) is hindered by downy mildew infection, particularly at the seedling stage, leading to quantitative and qualitative crop losses due to discolored lesions and reduced harvest quantity.
Innovation Solution
Development of a new cultivated rocket variety, 88-CR31138 RZ, exhibiting traits such as an erect leaf attitude, medium to dark greyish green leaf color, and medium leaf width, which is deposited under NCIMB Accession No. 44647, providing resistance to downy mildew and maintaining crop quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cultivated rocket varieties are grown, then they exhibit normal growth and leaf development, but they suffer from downy mildew infection leading to crop losses
Solution Approach 1:
The patent applies parameter changes by developing a new cultivated rocket variety (88-CR31138 RZ) with altered genetic parameters that confer resistance to downy mildew. The variety exhibits specific morphological parameters including erect leaf attitude, medium to dark greyish green leaf color, and medium leaf width, which are associated with enhanced disease resistance while maintaining productivity
2Object-affected harmful factors
If cultivated rocket plants are infected with downy mildew, then the disease develops under cool and moist conditions, but this leads to discolored lesions and necrotic spots that destroy leaf quality
Solution Approach 1:
The patent converts the harmful effect of downy mildew infection into a benefit by selecting and breeding plants that exhibit resistance to the disease. The new variety 88-CR31138 RZ demonstrates the ability to withstand downy mildew pressure, transforming the previously harmful pathogen interaction into a demonstration of enhanced plant resilience and quality maintenance
3Reliability
If downy mildew infection occurs at the seedling stage, then young seedlings can die, but this results in severe quantitative losses at the early growth stage
Solution Approach 1:
The patent applies preliminary action by conducting disease resistance screening and selection during the breeding process to pre-establish resistance in the new variety 88-CR31138 RZ. This preliminary genetic selection ensures that seedlings are inherently resistant to downy mildew before field deployment, preventing mortality and maintaining seedling population
