Abstract

Rhizomania caused by Beet necrotic yellow vein virus (BNYVV) and storage losses are serious sugar beet production problems. To identify sugar beet cultivars with resistance to BNYVV and evaluate storability, 22 commercial cultivars were screened by growing them in a commercial sugar beet field naturally infested with BNYVV in Declo, ID during the 2009 growing season in a randomized complete block design with 4 replications. At harvest on 13 October 2009, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building. Storage samples were evaluated for fungal growth known to correlate with sucrose loss. Depending on cultivar, surface fungal growth ranged from 5 to 42% by 18 February 2010. Overall, the commercial cultivars had an average sucrose reduction of 33% after 131 days in storage. Improving cultivar performance for resistance to sucrose loss in storage and rhizomania has the potential to lead to considerable economic benefit to the sugar beet industry.
