Searching for wheat resistance to aphids and wheat bulb fly in the historical Watkins and Gediflux wheat collections.: Wheat resistance to aphids and wheat bulb fly
Insect pests can reduce wheat yield by direct feeding and transmission of plant viruses. Here we report results from laboratory and field phenotyping studies on a wide range of wheat, including landraces from the Watkins collection deriving from before the green revolution, more modern cultivars from the Gediflux collection (north-western Europe) and modern UK Elite varieties, for resistance to...

This virus complex is considered to be the most serious disease of winter wheat in the western Great Plains. One component of managing this disease has be...
متن کاملTan Spot Disease of Wheat : race characterization
Tan spot, one of the most important diseases of wheat, is caused by Pyrenophora tritici-repentis, a necrotrophic fungus which survives in wheat straw. Methods of disease control include fungicide application, crop rotation, and the use of resistant cultivars; however, in Brazil there are no cultivars in the market with a good level of resistance. In North America, a system of race identificatio...
