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, 26 commercial cultivars were screened by growing them in a sugar beet field infested with BNYVV in Kimberly, ID during the 2021 growing season in a randomized complete block design with 6 replications. At harvest on 4-5 October 2021, roots were dug and evaluated for symptoms of rhizomania and also placed in an indoor commercial sugar beet storage building. After 132 days in storage, samples were evaluated for surface rot, weight loss, and sucrose loss. Surface root rot ranged from 12 to 53%, weight loss ranged from 14 to 23%, sucrose losses ranged from 28 to 68%, and estimated recoverable sucrose ranged from 766 to 9,622 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.
