True potato (Solanum tuberosum) seed (TPS) is used for preservation of variable genetic lines of wild and cultivated potatoes (Hawkes et al., 2000) and for propagation of food crops in some developing countries. TPS has advantages over seed potato tubers in storage and transportation and favors lower virus infection levels...
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...
Solanum species differ in their degree of frost tolerance and cold acclimation capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive, incapable of cold acclimation, and have a maximum freezing tolerance of –3°C. Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation and –10ºC post-acclimation. Breeding attempts...
Potato Virus Y (PVY) imposes serious limitations on potato yield, quality and tuber seed
production. Traditional PVY screening requires artificial inoculation under controlled
conditions followed by ELISA to test for PVY. This method is very tedious and time
consuming thus prohibiting the screening of large segregating populations. The genes
RYadg...
