| 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, 30 experimental 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 6 to 82%, weight loss ranged from 9.1 to 17.5%, sucrose losses... |

| Rhizomania is a serious yield limiting viral disease in sugarbeet first identified in California, USA in 1984. The disease has since spread to all major production areas in the United States. Rhizomania is caused by Beet necrotic yellow vein virus (BNYVV) and vectored by the plasmodiophorid (a fungal-like organism), Polymyxa betae. The virus survives inside the thick-walled resting spore of the vector in the soil, which can remain viable for many years. As a result, once a field is infested, using crop rotation and non-host crops will not be effective for controlling the disease. In the spring with near saturated soil conditions, the resting spore will germinate to release zoospores when in close proximity to sugarbeet roots. The zoospores will... |

| Rhizoctonia root and crown is an important disease problem in sugar beet caused by Rhizoctonia solani and also shown to be associated with Leuconostoc. Since, the initial Leuconostoc studies were conducted with only a few isolates and the relationship of Leuconostoc with R. solani is poorly understood, a more thorough investigation was conducted. A total of 203 Leuconostoc isolates were collected from recently harvested sugar beet roots in southern Idaho and southeastern Oregon during 2010 and 2012: 88 and 85% L. mesenteroides, 6 and 15% L. pseudomesenteroides, 2 and 0% L. kimchi, and 4 and 0% unrecognized Leuconostoc sp., respectively. Based on 16S rRNA sequencing, haplotype 11 (L. mesenteroides isolates) comprised 68 to 70% of the isolates both... |

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,... |

| Thirty-one sugar beet germplasm breeding lines and releases produced by the USDA-ARS sugarbeet program at Salinas, CA, and one line from the USDA-ARS sugarbeet program at East Lansing, MI, were evaluated for resistance to rhizomania under south-central Idaho conditions at Twin Falls, ID. The field had been identified as having Beet necrotic yellow vein virus (BNYVV), which overcomes resistance conditioned by the Rzl gene. Single-row plots 10 ft long with 22-in. spacing were planted on 23 May 05. Plants were thinned to 4 to 6-in. spacing in mid-Jun. The materials were predominantly multigerm; they were hand thinned to single plants during the first week of Jul. The trial layout was a randomized complete block with eight replicates, however, the... |

| Twenty-seven experimental sugar beet cultivars and five commercial check cultivars were evaluated in a sprinkler-irrigated sugar beet field near Kimberly, ID where sugar beet were grown in 2009. The field trial was conducted in a field that contained Portneuf silt loam soil and relied on natural infection for rhizomania development. The plots were planted on 26 Apr 10 to a density of 142,560 seeds/A, and thinned to 47,520 plants/A on 12 Jun. Plots were four rows (22-in. row spacing) and 24 ft long. The experimental design was a randomized complete block design with four replications per cultivar. The crop was managed according to standard cultural practices. The plants were mechanically topped and the center two rows were collected with a mechanical... |

| Rhizomania caused by the Beet necrotic yellow vein virus (BNYVV) is a worldwide problem that can lead to loss of tonnage and lower percent sucrose in the field. BNYVV can also reduce the storability of roots. To identify germplasm with resistance to these problems, 18 sugarbeet germplasm lines developed by the USDA-ARS Ft. Collins sugarbeet program and four check cultivars were screened in a field experiment arranged in a randomized complete block design with 6 replications. During the growing season plants were evaluated for foliar rhizomania symptoms. At harvest on 4 October 2012, roots were evaluated for rhizomania symptoms and then placed into an indoor commercial sugarbeet storage building in Paul, ID. Foliar symptoms ranged from 0% for resistant... |

| Fifty-seven sugar beet (Beta vulgaris L.) lines from the USDA-ARS Ft. Collins sugar beet program and four check cultivars were screened for resistance to Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania, and storage rot. The rhizomania evaluation was conducted at the USDA-ARS North Farm in Kimberly, ID. Seed of the sugar beet germplasm lines was planted on April 21. One-row plots, 10 ft long with 22-in row spacing between rows were arranged in a randomized complete block design with 4 replications. The trial relied on natural infection for rhizomania and storage rot development. The plots were rated for foliar symptom (percentage of plants with yellow, stunted, upright leaves) development on July 8 and 20. At harvest, roots in... |

| Rhizomania in the field and fungal root rot in storage can both lead to significant sucrose losses in sugar beet roots. In an effort to reduce these losses, sugarbeet germplasm developed by the USDA-ARS Kimberly sugarbeet program was evaluated for resistance to both these disease problems. Nine sugarbeet lines and four check cultivars were arranged in a randomized complete block design with six replications and grown in a field known to be infested with Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania. The plants were evaluated for foliar symptoms in July, August, and September. Plots were harvested in October, roots were evaluated for rhizomania root symptoms, and roots from each plot were also placed in a commercial indoor storage... |

| Resistance to rhizomania is a basic requirement for cultivars’ approval for commercialization. The objectives of this research were to identify germplasm accessions that carry resistance genes to rhizomania and storage root rots. Twenty-one sugar beet (Beta vulgaris L.) germplasm from the USDA-ARS Kimberly sugar beet program and four check cultivars were screened for resistance to Beet necrotic yellow vein virus (BNYVV) during the 2011 growing season and during the 2011/2012 storage period for fungal growth in an indoor storage. The rhizomania evaluation was conducted at the rhizomania nursery in the USDA-ARS North Farm in Kimberly, ID. The crop was managed according to standard cultural practices and pest control. The plots were rated twice (4 weeks... |

| Sugar beet germplasm and commercial check cultivars were evaluated in a sprinkler-irrigated sugar beet field near Kimberly, ID where sugar beet was grown in 2009. The soil type was Portneuf silt loam. The field trial relied on natural inoculum for rhizomania (caused by Beet necrotic yellow vein virus) development. The seed was treated with clothianidin (2.1 oz a.i. per 100,000 seed) to limit pests and curly top. The plots were planted on 26 Apr to a density of 142,560 seeds/A, and thinned to 47,520 plants/A on 12 Jun. Plots were single rows (22-in. row spacing) and 10 ft long.
