an evaluation on the resistance of the germplasm of cucumber against downy mildew of cucurbitaceae (pseudoperonospora cubensis)
abstract downy mildew of cucurbits is one of the most important diseases of cucumber in humid areas and greenhouses. damage of disease is estimated 50% to 100% in suitable climatic conditions. therefore, achieving resistant or tolerant genotypes can be designed as the most important and safe method to reduce the damage and increase the benefits of cucumber farming. in order to evaluate the resi...
متن کاملDiagrammatic scale to assess downy mildew severity in melon
Hortic. bras., v. 27, n. 1, jan.-mar. 2009 The Northeast region of Brazil responds for nearly 95% of the national melon (Cucumis melo L.) production. Located at this region, States of Rio Grande do Norte and Ceará supply respectively 55 and 28% of the total melon harvested in Brazil (FNP, 2007). The expansion of the area used for melon production in this region, in addition to an intensive year...
متن کاملResurgence of cucurbit downy mildew in the United States: Insights from comparative genomic analysis of Pseudoperonospora cubensis
Pseudoperonospora cubensis, the causal agent of cucurbit downy mildew (CDM), is known to exhibit host specialization. The virulence of different isolates of the pathogen can be classified into pathotypes based on their compatibility with a differential set composed of specific cucurbit host types. However, the genetic basis of host specialization within P. cubensis is not yet known. Total genom...
متن کاملSeed Transmission of Pseudoperonospora cubensis
Pseudoperonospora cubensis, an obligate biotrophic oomycete causing devastating foliar disease in species of the Cucurbitaceae family, was never reported in seeds or transmitted by seeds. We now show that P. cubensis occurs in fruits and seeds of downy mildew-infected plants but not in fruits or seeds of healthy plants. About 6.7% of the fruits collected during 2012-2014 have developed downy mi...
متن کاملEpidemiology and population biology of Pseudoperonospora cubensis: a model system for management of downy mildews.
The resurgence of cucurbit downy mildew has dramatically influenced production of cucurbits and disease management systems at multiple scales. Long-distance dispersal is a fundamental aspect of epidemic development that influences the timing and extent of outbreaks of cucurbit downy mildew. The dispersal potential of Pseudoperonospora cubensis appears to be limited primarily by sporangia produc...
