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, 33 commercial cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2014 growing season in a randomized complete block design with 6 replications. At harvest on 24-25 September 2014, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building. After 138 days in storage, samples were evaluated for surface rot, weight loss, and sucrose loss. Surface root rot ranged from 7 to 82%, weight loss ranged from 9.4 to 19.1%, sucrose losses ranged from 23 to 85%, and estimated recoverable sucrose ranged from 931 to 8,798 lb/A. Given these response ranges, selecting cultivars for rhizomania resistance and combining this resistance with storability will lead to considerable economic benefit for the sugar beet industry.
