1 Soybean J.H. Orf, S.L. Naeve, P.J. Schaus and A. Killam Varietal Trials Results, January 2007 Minnesota Agricultural Experiment Station scientists annually conduct these tests of adapted public and private soybean varieties. Companies are charged a fee for each variety they enter and these fees partially cover the costs of conducting these tests. One of the stipulations of the testing program is that the company is marketing or intends to begin marketing the variety in the next growing season. The 2006 growing season was drier than normal early then adequate moisture occurred during pod filling. It was also warmer than normal in The locations in the northern zone were affected to a greater degree than locations in the southern zone. In contrast to 2004 even the latest recommended varieties matured. Tables 1 to 3 present data from the regular public and private variety tests that are conducted annually at various locations within the northern, central and southern production zones. The map shows test locations and zone boundaries. All of these tests were planted between May 4 and June 6 at planting rates of 160,000 plants/acre. Herbicides were used as necessary for good weed control. Row spacings were 30 inches at Becker and Jackson and 10 inches at other locations. Plot combines were used to harvest the plots. The 2005 data from Becker were not included due to a late season hailstorm. Table 4 provides results of the very early (northern Minnesota) Minnesota Variety tests. These locations were added to provide data for environments not represented by the other location tests. Tables 4 to 7 provide results from specific tests of available Roundup Ready varieties adapted to the far northern, northern, central, and southern production zones. Data from 2005 from Becker was not included due to a late season hailstorm. Tables 8 and 9 provide results from the special performance tests of soybean cyst nematode resistant varieties in infested field sites near Lamberton, Waseca, and Otisco in the southern zone; and Gaylord, Atwater and Hector in the central zone. Non-infested field sites were located near Lamberton, Jackson, and Waseca in the southern zone and Morris, Becker and Rosemount in the central zones. Planting techniques were the same as the regular performance tests. Tables 10 to 12 provide performance and characteristics data from special-use soybean variety tests. These tests were conducted to provide reliable data for growers who are interested in producing these types of soybeans, which are typically grown under contract. Table 13 provides important variety characteristics of publicly developed varieties entered in the 2006 tests. To better understand and use the data provided in these tables, please read the following additional information very carefully. Relative Maturity and Calendar Dates of Maturity Soybeans respond to changing day length, so the actual calendar date of maturity achievement is affected 54 by latitude. Each variety has a narrow range of north-south adaptation. Soybean yield and quality are assured if a variety arrives at physiological maturity before a season ending freeze occurs. This date is determined visually by noting the actual date when 95 percent of the pods show their genetically programmed mature color. These dates for 2006 are provided in the tables. Harvest dates are typically 7 to 14 days later, depending upon drying conditions. Relative maturity ratings are also provided for each variety. These ratings consist of a number for the maturity group designation (000, 00, 0, 1, 2) followed by a decimal and another number, ranging from 0-9, which indicates a ranking within each maturity group. For example the variety MN0302 indicated as 0.3, making it an early group 0 variety, while MN0901, with a 0.9 rating, is the latest. These values for public varieties are developed after observing them for several years in many locations. Relative maturity ratings for private varieties in these tables were provided by their owners, and were developed in a similar manner. Yield Because maturity is a very important attribute, varieties are arranged in the tables in order of their actual 2006 calendar date of maturity and not yield performance. Later-maturing varieties can usually be expected to have higher yields than earlier maturing types. If you wish to correctly compare yields, do so only between varieties with similar calendar dates of maturity, usually within 3 to 5 days. More reliable comparisons can be made using variety yields from several consecutive years. All yield determinations were made from replicated tests harvested with a plot combine.

Far Northern Zone Southern Zone In 2006 the yield information is presented as a percent of the mean of the test. The actual mean value is given at the bottom of each table. Values over 100 indicate the variety had a yield greater than the mean while those less than 100 have a yield less than the mean. LSD values associated with data in these tables are measures of variability within the trials. The LSD values are given on the percent of mean data not the actual yields. If a yield difference between two varieties within a single column exceeds this LSD value you can assume that the higher-yielding variety was truly better yielding. A 20% level of significance is used in all tables, which means that yield differences exceeding the stated LSD value are real 80% of the time. Chlorosis These ratings are based on how much of the leaf area was yellowing in tests conducted on high-lime (high ph) soils near Granite Falls in Comparing chlorosis scores of varieties permits you to estimate how well they perform relative to each other. Actual chlorosis ratings can vary depending on the specific site and year of test. Specific scores and evaluation dates from the 2006 tests are provided at the web site Sometimes chlorosis tolerance is described with numerical scores rather than word descriptors. These systems are compared below. Numerical Score Word Description 1-5 scale 1-9 scale Rating 1to2 1to2.5 Tolerant(T) 2.1 to to 5 Moderately Tolerant (MT) 3.1 to to 7.5 Moderately Susceptible (MS) 4.1 to to 9 Susceptible (S) Protein and Oil Protein and oil values were determined from mature seed using near infrared reflectance analysis equipment. The table values are for the 2006 season only. The protein and oil information is presented on a percent of the mean of the test. The actual mean values are given at the bottom of each table. Values over 100 indicate the protein and/or oil contents of the variety were greater than the mean value while those less than 100 have protein and/or oil contents less than the mean. Absolute values of protein and oil can vary from year to year. The mean protein and oil values are expressed on a 13% moisture basis. This formula converts the protein and oil values to another moisture basis: 100-desired moisture x The value of an acre of soybeans can be calculated by multiplying the APV by the yield in bushels per acre. Phytophthora Phytophthora root rot can cause significant yield reductions if susceptible varieties are planted in poorly drained, infested fields. There are several known races of this fungus, so it is important to know which are present in your field. Genes can be incorporated into varieties to provide resistance to specific races of this disease. Some published information refers to Phytophthora tolerance or field resistance, which is not race specific and should not be confused with race-specific resistance. Reliable tests for tolerance have not yet been developed. Data tables in this report indicate which Phytophthora gene or genes is/are present in each variety. An N indicates the information was either not provided by the entering company or not verified by greenhouse evaluation. The above listing tells you which resistance genes provide resistance to the various races. Soybean Cyst Nematode Soybean Cyst Nematode (SCN) was first identified in Minnesota in 1978 and is now known to occur in many Minnesota counties where the soybean is grown. Both the area of infestation and numbers of nematodes per unit of soil appear to be increasing. Several races of this pest are known to occur in Minnesota. When SCN numbers are high, significant yield losses can occur. Rotations to non-host crops and planting of resistant varieties can assist in reducing nematode populations as well as reducing its impact on yield. Yield performance of susceptible (S), and resistant (R) varieties planted in infested and non-infested fields in central and southern Minnesota are provided in tables 8 and 9. Genes for resistance to various races of Phytophthora root rot. Gene Races Rps1,1a Rps1b Rps1c Rps1k Rps3 Rps4 Rps6 87 protein or oil value given in the table The value of a bushel of soybeans (APV) based on its oil and protein content can be calculated by: APV = 60 [Po (X) + Pm (Y)].44 Where: APV = Approximate value of a bushel of soybeans Po = soybean oil price (in $ per pound) Pm = price of 44% meal (in $ per pound)* X = oil content at 13% moisture (in decimals) Y = protein content at 13% moisture (in decimals) And: * price of meal $/ton = $/pound 2,000 The value of an acre of soybeans can be calculated by multiplying the APV by the yield in bushels per acre

3 For proper management of fields with SCN it is recommended that varieties with an R rating be planted. If the SCN population numbers are relatively low (<3000) a variety with an MR rating might be considered. Even though SCN reproduction is less on MS-rated varieties than S-rated varieties, for practical purposes these varieties should not be considered for planting in fields where SCN is present and being managed. Management information is available from this web site, or from the Minnesota Soybean Research and Promotion Council, 360 Pierce Avenue, Suite 110, North Mankato, MN 56003, , web site White Mold White mold, also known as Sclerotinia stem rot, develops in infested fields when high relative humidity and moderate temperatures occur during soybean flowering. Planting less susceptible varieties in wider row spacings or at lower populations is the most effective method of reducing white mold severity. Accurate ratings for soybean variety resistance to white mold are difficult to obtain because both infection and disease development are dependent on weather conditions. Because of this variability, a variety s performance can change significantly among locations and years depending on the interaction of plant development, precipitation, relative humidity, and temperature. White mold severity also tends to be greater if lodging occurs. Growers concerned about variety performance in the presence of white mold should select varieties that show consistently less white mold during several years of testing. Brown Stem Rot Brown stem rot (BSR) is a fungal disease that can cause yield losses in certain situations. The disease occurs most frequently when soybeans follow soybeans but can occur where soybeans are planted every other year. Resistant varieties, or longer rotations, assist in the management of this disease. MN0304, MN0902CN, MN1302, Freeborn, IA1006, and IA2008R are available public varieties with resistance to BSR. Gold Country 8716RR, SOI 0574RR, SOI 1540RR, SOI 1430RR, SOI 1534RR, Viking 1574RR, and Viking 1776RR are privately developed varieties reported to be resistant to BSR. Some information refers to tolerance or field resistance. Reliable tests for tolerance or field resistance have not yet been developed. Special Use Varieties There continues to be increased interest in producing soybeans with special characteristics important to specialty food product manufacturers. Soybean scientists previously developed some of these special-use varieties, which were general releases, but more recently varieties have been released under exclusive or nonexclusive licenses to specific companies who then contract with growers for production. For further information contact MCIA at web site and telephone number Brand Names Versus Variety Names Brand names and variety names are different and are meant to be used for different purposes. Brand names refer to the seed source or, i.e. the person labeling and selling the seed. Brand does not refer to the genetic makeup of the seed. Variety names refer to the genetic makeup of seed and they may only refer to a specific genetic makeup. Plant breeders are constantly improving varieties but whenever the genetic makeup is changed a new variety is created and it must have a new variety name. The rate at which new varieties are being developed has dramatically increased in recent years. Branding is a useful way for companies to market products without having to constantly redo the identification and promotional information they offer. If a farmer wishes to spread risk by planting products with different genetic makeup, the variety name must be used to determine if two products are truly different. Relying on a brand name alone to make this determination may not result in different varieties being planted.
