| Sugarbeet (Beta vulgaris L. subsp. vulgaris) is an industrial crop grown commercially as a hybrid, with sucrose refined from the root as the plant constituent of interest. Yield of refined white sugar produced per unit area is a complex trait. Sugar yield is calculated by the root weight times the proportion of root that is sucrose, minus the amount of sucrose lost during processing, often expressed as percent loss to molasses or juice purity. Yields have risen in the last 100 yr from about 10% sucrose and 22.4 Mg ha−1 (10 t ac−1) to 18% sucrose and more than 65 Mg ha−1 (29.3 t ac−1). There also has been a shift in acreage from the western United States (especially California and Colorado) to the northern Midwest (Red River Valley). Although not all of... |

| Curly top caused by Curtovirus species is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas. Host resistance is the primary defense against this problem but resistance in commercial cultivars is only low to intermediate. In order to identify novel sources of curly top resistance, thirty Plant Introduction (PI) Lines were screened in a disease nursery in 2013. The lines were arranged in a randomized complete block design with three replications. A curly top epiphytotic was created by releasing approximately 6 viruliferous beet leafhoppers per plant at the four- to six-leaf growth stage on 27 Jun. Foliar symptoms were evaluated on 16 Jul using a scale of 0-9 (0 = healthy and 9 = dead) in a continuous manner.... |

| Seventeen sugar beet (Beta vulgaris L.) lines from the USDA-ARS Ft. Collins sugar beet program were screened for resistance to Beet severe curly top virus (BSCTV) and other closely related Curtovirus species in 2012. Commercial sugar beet cultivars Monohikari and HM PM90 were included as susceptible and resistant checks, respectively. The curly top evaluation was conducted at the USDA-ARS North Farm in Kimberly, ID which has Portneuf silt loam soil and had been in alfalfa in 2011. The field was plowed in the fall and in the spring, fertilized (90 lb N and 110 lb P2O5/A) on 16 Apr 12, sprayed with Ethotron (2 pt/A), and roller harrowed. The germplasm was planted (density of 142,560 seeds/A) on 21 May. The plots were two rows 10 ft long with 22-in row... |

| Rhizoctonia root rot caused by Rhizoctonia solani can cause serious economic losses in sugar beet fields. Preliminary evidence suggests there could be interactions between different strains and resistance sources. Thus, field studies were conducted to determine if nine R. solani AG-2-2 IIIB strains varied for virulence when compared with a non-inoculated check and interacted with five sugar beet lines (four resistant lines and a susceptible check). The studies were arranged in a randomized complete block design with six replications. Roots were evaluated for surface rot and internal fungal and bacterial rot in September. All strains were virulent on the susceptible check, FC901/C817, and had the same ranking (r = 1.0) regardless of disease variable.... |

| Thirty wild beet (Beta vulgaris subsp. maritima (L.) Arcang) accessions from the Beta Collection of the USDA-ARS National Plant Germplasm System were screened for resistance to Beet severe curly top virus (BSCTV) in 2009. The curly top evaluation was conducted at the USDA-ARS North Farm in Kimberly, ID which had been in beans in 2008. The field was plowed in the fall, fertilized (75 lb N/A and 75 lb P2O5/A) on 22 Apr 09, sprayed with Ethotron (2 pt/A), and roller harrowed. The germplasm was planted (density of about 143,000 seeds/A) on 18 May. The plots were two rows 10 ft long with 22-in row spacing and arranged in a randomized complete block design with three replications. A resistant breeding line from Betaseed, Inc., G6040, was included as a resistant... |

| 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 sugar beet (Beta vulgaris L.) germplasm lines produced by the USDA-ARS Ft. Collins sugar beet program and two commercial check cultivars [SV2012RR (susceptible) and HM PM90 (resistant)] were screened for resistance to Beet curly top virus (BCTV). The curly top evaluation was conducted at the USDA-ARS North Farm in Kimberly, ID, which had been in barley in 2014. The germplasm was planted (density of 142,560 seeds/A) on May 27. The plots were two rows 10 ft long with 22-in row spacing and arranged in a randomized complete block design with three replications. The fields were sprinkler irrigated, cultivated, and hand weeded as necessary. Plant populations were thinned on June 20 Plants were inoculated at the four- to six-leaf growth stage on June... |

| 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... |

During the growing season plants were evaluated for foliar rhizomania symptoms. At harvest on 29 September, roots were evaluated for rhizomania symptoms and then placed into an indoor commercial sugarbeet storage building in Paul, ID.

| 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. The experimental design was a randomized complete block design with eight replications per entry. The crop was managed according to standard cultural practices, except for... |

| Rhizoctonia root rot causes serious losses on sugar beet worldwide. In order to help explain why Rhizoctonia root rot management practices have not performed well in some areas of the Intermountain West (IMW), a survey was conducted. In the IMW from 2004 to 2006, 94 Rhizoctonia solani field isolates were collected from sugar beet roots. These field isolates were compared with 19 reference strains and 46 accessions from GenBank for genetic diversity based on sequencing of the ITS-5.8S rDNA region. Greenhouse pathogenicity tests on sugar beet and silage corn were conducted and plant damage was assessed using a randomized complete block design with at least four replications. The majority (92%) of the isolates had identity with the AG-2-2 IIIB (48%) or... |
