INTRODUCTION
Soybean variety tests are conducted annually by the Alabama Agricultural Experiment Station. The 7 locations used represent the major soil and climatic regions of Alabama. These locations are divided into logical soybean growing regions. The regions and locations are: Region Northern Central Southern Black Belt Gulf Coast Location Belle Mina, Crossville Tallassee, Shorter Brewton Marion Junction (2 soils) Fairhope

EXPERIMENTAL PROCEDURES
The standard tests were conducted as a randomized complete block design with four replications. Standard plot size was four 30- to 38-inch rows by 20 feet long. Fifteen feet of the middle two rows were harvested for yield. Seeding rate was 10 viable seeds per foot of row. The Group IV test was drilled with seven 7-inch rows. Seeding rate was five viable seeds per foot of row. Data were collected on seed yield, moisture, lodging, shattering, plant height, and maturity date. Plot yields were adjusted to 13 percent moisture and converted to bushels (60 pounds) per acre. Lodging was scored on a scale of 1 to 5 as follows: 1 - almost all plants erect. 2 - either all plants leaning slightly (less than 45%) or a few plants down. 3 - either all plants leaning moderately (approximately 45%) or 25 to 50 percent of the plants down. 4 - either all plants leaning more than 45% or 50 to 80 percent of the plants down. 5 - more than 80 percent of the plants down. Shattering was rated on a scale of 1 to 5 based on performance of the border rows 14 days after maturity. A rating of 1 indicates no shattering, a rating of 3 indicates a 4 to 8 percent shattering, and a rating of 5 is 20 percent or more shattering. Plant height was determined by measuring from the ground to the top of the plant at maturity. Maturity date was the day 95 percent of the pods achieved mature pod color. Harvest was approximately 7 to 10 days later.

SEASONAL CONDITIONS
Rainfall for 2008 is shown in Table 19. The normal planting dates for the standard tests are the first week in May, May 15-25, and May 25 to June 5 for northern, central, and southern Alabama locations, respectively. Soybean rust was observed at the Gulf Coast Research and Extension Center in Fairhope, AL. The soybean rust leaf symptoms were first observed in the lower leaf canopy in mid September at the R6 full seed growth stage. Rust severity ranged from 2.5% of the leaf area infected up to 25.0% of the leaf infested which was a low level of disease incidence in this area. On 24 September, soybean plants had matured to the R7 growth stage. AU 02-2814, USG 5601T, AU 02-3104, Asgrow AG 7201supported the least amount of rust as compared to Osage and DP 6568RR. All other varieties had similar rust ratings.

COMPARING VARIETIES
To aid in determining real yield differences, a statistical analysis of variance was performed on the data from each location. The L.S.D. (least significant difference) and C.V. (coefficient of variation) are reported for each location’s 2008 test, and for the location’s or region’s 2- and 3-year averages. The difference in yield of two varieties must exceed the L.S.D. value for one variety to be considered superior to others in yield in that particular test. The C.V. is a measure of the variability in an experiment. An increase in its value indicates an increase in the unexplained variability. Since the performance of varieties varies with location and year, long-term averages from several locations are more reliable than 1-year performance. Three-year regional averages are considered a reliable evaluation of the relative performance of varieties. However varietal rankings may change among years and among locations. This change in rankings is measured by the significance of variety x location, variety x year, variety x location*year interaction. These interactions were significant in all cases. Thus, care should be exercised when extrapolating results from one location or year to another.
