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, 24 experimental cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2011 growing season in a randomized complete block design with 4 replications. At harvest on 18 October 2011, 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 root discoloration (rot and fungal growth) ranged from 2 to 37%. Overall, the experimental cultivars had an average sucrose reduction of 38% after 120 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.
