Optimizing virus detection in potato breeding populations

Creator:: Hane, Dan C.
Abstract:: Virus contamination in a potato breeding program can seriously disrupt the variety development process. Experiments were conducted from 1989 through 1993 to: evaluate the extent to which Potato Leafroll Virus (PLRV) and Potato Virus Y (PVY) can invade a breeding program, determine viral spread within hills and within individual tubers,...

The potato : composition, non-enzymatic browning and anthocyanins

Creator:: Rodriguez-Saona, Luis Enrique
Abstract:: Chipping varieties and model systems were used to determine the role of potato constituents on chip color. Composition was evaluated by HPLC and chip color measured using a ColorQuest colorimeter. Reducing sugar (RS) content did not completely explain color quality when present in low concentrations (<60 mg/lOOg). Levels of ascorbic...

Monitoring potato leafroll virus movement in differentially aged potato (Solanum tubersom L.) plants with an immunosorbent direct tissue blotting assay

Creator:: Whitworth, Jonathan L.
Abstract:: Potato leafroll virus (PLRV) causes yield and quality losses in potato. PLRV is identified by plant symptoms and serological tests such as an enzyme-linked immunosorbent assay (ELISA). A similar serological test, direct tissue blotting assay (DTBA), was used to detect and monitor PLRV movement in field-inoculated Russet Burbank plants and...

Entomopathogenic nematodes for biological control of the Colorado potato beetle, Leptinotarsa decemlineata (Say)

Creator:: Armer, Christine Andrea
Abstract:: The Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), is the most devastating foliage-feeding pest of potatoes in the United States. Potential biological control agents include the nematodes Heterorhabditis marelatus Liu & Berry and Steinernema riobrave Cabanillas, Poinar & Raulston, which provided nearly 100% CPB control in previous laboratory trials. In...

A potato growth and production model

Creator:: Apple, Jeanne Debons
Abstract:: A potato plant growth and production model is developed with the objectives of analyzing management alternatives and exploring the nature of the early dying syndrome. The geographic area of focus was the centerpivot irrigated circles of Oregon's Columbia Basin. A problem analysis of the potato production system of this area,...

Biology and management of Meloidogyne chitwoodi using oxamyl on potato in the western United States

Creator:: David, Nicholas L.
Abstract:: Field trials were conducted during 2001 to 2003 to investigate soil population dynamics of Meloidogyne chitwoodi, tuber symptom suppression using oxamyl, and post-harvest tuber symptom development on short-season potato varieties Russet Norkotah and Russet Nugget (San Luis Valley only). The experiments were located in the San Luis Valley in Colorado,...
