Twenty Russet Burbank seed lots were collected from four states and one Canadian Province in 1988 and planted in replicated trails at Powell Butte and Hermiston, Oregon as part of a two year study to quantify clonal differences in the cultivar. Samples of each seed lot were concurrently increased and...

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...
