GENETIC VARIABILITY IN THE CYST AND ROOT-KNOT NEMATODES

(WYO-399-05)

Plant-parasitic nematodes cause an estimated 10-14% average annual yield loss among the world's major crops (Sasser and Freckman, 1987). Losses in United States' major crops due to plant-parasitic nematodes are estimated to range from minimal in some localities to as high as 15% in other areas (Koenning et al., 1999; McSorley et al., 1987). The accurate identification of nematode species is beneficial and necessary for national and international regulatory and quarantine agencies relative to free trade and economics. The nematology community has repeatedly advocated the need for funding support focused on the basic and applied research required to advance alternative management approaches. The proposed project addresses these needs directly for the most important groups of plant parasitic nematodes, by building on advances made in the W-186 project over the last 10 years.
