Occurrence and Molecular Characterization of Strobilurin Resistance in Cucumber Powdery Mildew and Downy Mildew

Image Recognition of Grape Downy Mildew and Grape Powdery Mildew Based on Support Vector Machine

In order to realize automatic disease diagnosis and provide related information for disease prediction and control timely and accurately, the identification and diagnosis of grape downy mildew and grape powdery mildew was conducted based on image recognition technologies. The method based on K_means clustering algorithm was used to implement unsupervised segmentation of the disease images. Fift...

QTLs for Downy Mildew Resistance and Their Association with LRR-RLK Resistance Gene Analogs in Cucumber

Downy mildew (DM) caused by the obligate oomycete Pseudoperonospora cubensis is an important disease of cucumber and other cucurbit crops. In the United States, for more than 50 years, DM was effectively controlled in cucumber through host resistance conferred mainly by the dm-1 derived from PI 197087, which was overcome in 2004 due to the appearance of a new pathotype. Resistance sources (for ...

Heritability and Genetic Variance Estimates for Resistance to Downy Mildew in Cucumber Accession Ames 2354

Downy mildew (DM) of cucumber (Cucumis sativus L.), caused by Pseudoperonospora cubensis, is a devastating disease of cucurbits. resistance is available but is not sufficient to eliminate the need for fungicides to control the disease. previously, the USDA plant Introduction collection of cucumber germplasm was screened in poland and North Carolina, and Ames 2354 was identified as highly resist...
