Waterlogged or saturated soil conditions are problematic to soybean [Glycine max (L.) Merr.] production systems in heavy clay and poorly drained soils, typical of a rice and soybean rotation in the Midsouth. The objective is to determine tolerant and sensitive varieties in a waterlogged environment. Seed of 295 currently available soybean cultivars (MG-4 and MG-5) were obtained from the Arkansas Variety Testing program. Single row plots 6.1 m in length and 0.81 m row spacing, with four replications, were planted in a Randomized Complete Block design. Field evaluations in 2004 and 2005 were conducted at Stuttgart, AR on a Calloway silt loam, fine smectitic, hyperthermic, Typic Aldaqualf. The plants were subjected to 7-10 cm of water above the soil surface for two weeks at the R1 growth stage. The lines were rated for visual injury based on the presence and frequency of foliar chlorosis and plant death one week after the water was removed and again three to four weeks later. The ratings were based on a 1 to 5 scale, 1 had no damage and 5 had more than 90% dead plants. The lines were evaluated within their respective maturity group (MG) classifications (early 4, late 4, early 5 and late 5) to determine the most tolerant and most sensitive cultivars. A normal distribution was observed within all of the four different maturity groups and each had lines exhibiting tolerance and sensitivity. The early MG-4 had the most tolerant lines with 21 out of 70. The late MG-4 had 8 out of 80 tolerant lines. In the early MG-5, 17 out of 90 lines exhibited tolerance. The late MG-5 had the lowest number of tolerant lines with 4 out of 82. In the future, the experiment will be expanded to determine the effects of waterlogging at different growth stages.
