3 University of Tennessee Agricultural Experiment Station D. M. Gossett, Dean, Knoxville Performance of Soybean arieties In 1985 Charles R. Graves Professor of Plant and Soil Science Soybean varieties in maturity group were evaluated at seven locations, maturity groups I & II at four locations, and maturity group I or less at five locations. Nine selected varieties in maturity group were evaluated at Crossville; no late-maturing varieties (maturity group I & II) were evaluated at this location. Three strain tests were conducted at Jackson in At the Ames Plantation, two plantings of varieties in maturity group were made about two weeks apart. The growing season was good in West Tennessee. Some drought stress occurred at Knoxville and Greeneville in East Tennessee. Yields for maturity group and I & II at Spring Hill were not included in the average due to missing data caused by Sencor injury in the seedling stage. Using the 1985 state average, there was only a 3 bushel difference among the first twenty varieties. The varieties that resisted lodging in maturity group were Essex, FFR 561, Pioneer brand 9561, Coker 5, Asgrow A51 and Bay. Coker 5 is an early, short growing variety that resists lodging. It performed better in 1984 than it did in At the Ames Plantation there was about a 10 bushel difference between the average yield of varieties planted on May 7 and those planted on May 18, with the May 7 planting producing the highest average yield. Using a two-year average yield, the leading varieties were Coker 5, Essex, FFR 561, Pioneer brand 52 and Coker 5. The highest yielding late-maturing varieties (maturity groups I & II) in 1985 were Asgrow A62, Ga Exp. 79-2, Shiloh and Hartz Deltapine 7 was very late in maturity. Most of these varieties stood well in 1985 with Shiloh, Ga Exp. 79-2, Deltapine 566, Funk Exp 2910 and GI 6 lodging the least. The new variety Leflore performed similar to Centennial in these trials in Using a three-year average for this late maturity group, Hartz 7126, RA 604, Asgrow A60 and Hartz 63R performed well. Twelve early-maturing (maturity group I) varieties were evaluated in Four of the varieties should have been evaluated with the medium maturity group. When maturity group I varieties are planted, they should be harvested as soon after maturity as possible to avoid deterioration of seed quality from adverse weather conditions. Thirty-seven commercial strains were evaluated at Jackson only, and these data are presented at the end of this report. There are 24 soybean varieties on the 1986 recommended list as seen in this report. Maturity group seems to be the most popular group grown in Tennessee.
