    Evaluation of Soybean Varieties in the Northern Uniform Soybean Test–Uniform Test III

    The Northern Uniform/Preliminary (UT-PT) Soybean Test is used to evaluate soybean varieties produced by public breeding programs in the Northern portion of the United States and Canada. In 2014, 10 public breeding programs participated in the Northern UT-PT III Tests (Uniform Test III and Preliminary Test IIIA and IIIB). Public breeders were allowed to enter varieties into the UT-PT Test in exchange for growing locations for the test. Material entered into the UT-PT Test is generally in advanced stages of a breeding program. Lines are evaluated one year in Preliminary Testing before being entered in Uniform Tests. Lines usually are evaluated in Uniform trials for two or three years prior to release as new varieties. The UT-PT Soybean Test is an efficient method for soybean breeders to get a wider geographic range of field evaluations on advance lines and to evaluate advance lines from other public programs, which could be used as parents in future crossing. Once a variety is released, these results also are used in cultivar releases, publications, and publicity

    Evaluation of Commercial Varieties in the Northern United States–Soybean Sudden Death Syndrome Commercial Variety Test

    Soybean sudden death syndrome (SDS) is a fungal disease causing foliar necrosis and early leaf drop. SDS can be a significant factor in soybean yield loss and has been found in fields across Iowa. The fungus is a good saprophyte and can grow well on plant debris in the field. The disease often is worse following corn. Although there is no complete resistance to SDS available in soybean, disease resistance is an important part of SDS disease management

    Evaluation of Soybean Commercial Varieties for Sudden Death Syndrome in Southern Iowa 2015

    Sudden Death Syndrome (SDS) is a major fungal disease of soybean in the Midwest. SDS has been found in all counties in Iowa. The large amount of rain in 2015 encouraged SDS foliar symptoms. Yield loss associated with SDS was noted even when foliar symptoms were negligible.</p

    Evaluation of Soybean Varieties in the Northern SCN Regional Soybean Test—SCN Regional Test IIin West Central Iowa

    Get PDF
    The Northern SCN Uniform/Preliminary (UT/PT) Regional Soybean Test is used to evaluate soybean varieties produced by public breeding programs in the northern portion of the United States and Canada. Lines are evaluated in locations with moderate to high SCN pressure. In 2015, five public breeding programs participated in the Northern SCN UT-PT II Trials (Uniform Test II and Preliminary Test II). Public breeders are allowed to enter varieties into the UT-PT Trials in exchange for growing locations for the trial. Material entered into the UT-PT Test is generally in advanced stages of a breeding program. Lines are evaluated one year in Preliminary Testing before being entered in Uniform Tests. Lines usually are evaluated in Uniform trials for two or three years prior to release as new varieties. The UT-PT Soybean Trials are an efficient method for soybean breeders to have a wider geographic range of field evaluations on advanced lines and to evaluate advanced lines from other public programs, which could be used as parents in future crossing. These results also are used in cultivar releases, publications, and publicity, once a variety is released.</p
