While OVT trials always display different pest, disease and production issues, the data from SMBSC shows SV genetics are very well-adapted to the SMBSC region. American Crystal These growers face a whole gamut of challenges, and the severity of diseases can vary across the Red River Valley. SV research and testing programs provide a lot of depth to understanding the environment and issues in order to select the best hybrids to meet these various challenges. For example, SV 375 is a high-sugar type with low SLM, which also contains good Cercospora and Aphanomyces tolerance. When Rhizoctonia creates yield challenges, SV 265 meets the challenge, and this tough, vigorous variety can emerge quickly and establish itself to provide excellent revenue at the end of the season. SV268 has excellent sugar (especially for early harvest) and combines excellent Aphanomyces tolerance for good stability in various areas of the Red River Valley. Whether it's Rhizomania, Cercospora, root aphid, Rhizoctonia, Aphanomyces or anything else, SESVanderHave is committed to delivering quality hybrids for Red River Valley growers. Amalgamated Sugar producers in Idaho and western Oregon have adapted to the times, where it is no longer just curly top at the top of the selection process. Rhizomania, Rhizoctonia, Cercospora and Aphanomyces are slowly limiting yield potential in the growing area, so the SV research program is designed to test and evaluate widely adapted varieties for the Idaho grower. For example, SV 183N has been well- received by growers in the nematode segment of Amalgamated, and SV182 is performing very well in growers' fields and early harvest reports. The shining light, however, is SV 099N, which has been stable; shows great sugar and high yield; and tolerates Rhizomania, Rhizoctonia, Aphanomyces, Cercospora, root aphid and many other ailments. The adaptability demonstrated in the Idaho area is certainly a function of the broad genetic background becoming more important for the Idaho region. Western Sugar North Western Sugar North has approved SV 1781N is a high sugar strong root aphid tolerant variety with decent fusarium tolerance. SV 1782N carries good Aphanomyces and cercospora tolerance to the sweet genetic package. The official trials in some cases are impacted by Fusarium, root maggot, Aphanomyces, etc., so the varieties will be thoroughly tested. Watch for SV products as SESVanderHave establishes its genetic base in the Western North region. Western Sugar South SV 1686N is a very sweet and high- yielding hybrid that delivers a portfolio of nematode, curly top, Cercospora and root aphid protection. This third-year variety was limited in 2020 but will be available for spring 2021 pending full approval. Watch for SV 1699N; this second-year variety looks very nice and grew very well in the official trials this past summer. Wyoming Sugar SESVanderHave continues to offer growers SV 1361N. This strong Rhizomania/ nematode product with moderate Fusarium tolerance has great adaptability to a variety of conditions. Lantic Sugar Growers will see SV 575 as a leading variety for Alberta. This variety is strong against Rhizoctonia, has a nice balance of yield and sugar, and carries a lot of the genetics that have brought success to many areas in the U.S. Across the U.S., SESVanderHave continues to breed, test and produce new and improved varieties for growers. n Wyoming Sugar grower John Snyder, right, with SESVanderHave U.S. sales and marketing manager Mike Dohman This SV research field in Idaho is designed to measure genetic potential of the new sugarbeet varieties adapted to the growing region.
