PERFORMANCE OF SOYBEAN VARIETIES IN ALABAMA, 1992

INTRODUCTION
Soybean variety tests are conducted annually by the Alabama Agricultural
Experiment Station. The 9 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 Location
Northern Belle Mina, Crossville
Central Camden, Prattville
Southern Brewton, Headland
Black Belt Marion Junction (2 soils)
Gulf Coast Fairhope
EXPERIMENTAL PROCEDURES
The standard tests were designed as a randomized complete block wit h
four replications. Plot size was four 24- to 36-inch rows 20 feet long.
Sixteen feet of the middle two rows were harvested for yield. Seeding rate
was 10 viable seeds per foot. of row. The early date t est was arranged in
incomplete lattice square design with four replications.
Data were collected on seed yield, moisture, lodging, shattering, plant
height, and maturity date. Plot yields were adjusted to 13 percent moisture
1 - almost all plants erect.
2 - either all plants leaning slightly (less than 450) 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 450 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 row 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 reached mature pod color. Harvest was approximately 7 to
10 days later.
SEASONAL CONDITIONS
Rainfall (Table 3) in April and May 1992 was such that planting dates for the
standard tests in northern Alabama were delayed. All other standard tests
were planted for optimum growth. The normal planting dates for full season
plantings in the regular tests are the first week in May, May 15-25, and
May 25 to June 5 for northern, central, and southern Alabama locations,
respectively. The rainfall for 1992 was normal in May at all locations and
was generally adequate for vegetative growth through July in central and
southern Alabama.
COMPARING VARIETIES
To aid in determining real yield differences, a statistical analysis
-7-
of variance is performed on the data from each location. The L.S.D. (least
significant difference) and C.V. (coefficient of variation) are given for each
location's 1992 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 the other 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.
A committee comprised of Department of Agronomy and Soils personnel
involved in soybean extension and research reviewed the past 3 years of
soybean variety test data to assemble the list of recommended varieties on
page 33. The acceptable varieties are not all equal in performance. Some are
outstanding in one or more characteristics; while others may possess a
satisfactory, although not outstanding combination of all characteristics.

APPENDIX
EVALUATION OF SOYBEAN CULTIVARS FOR REACTION TO FPOGEYE LEAF SPOT, 1992
P.F. Pace, D.B. Weaver, L.D. Ploper
2
One hundred ten public and private cultivars in Maturity Groups (MG) 4,
5, 6, 7, and 8 were evaluated under controlled conditions for reactions to a
virulent isolate of Cercospora sojina. The isolate was collected from Kirby
soybean at Jay, Florida, during 1991, and was found to be different from
described races 1 through 5 based on reaction to differentials (Phytopathology
71:334-336). Cultivars were divided into four MG classes: 4 and 5 (Expt. 1),
5 (Expt. 2), 6 (Expt. 3), and 7 and 8 (Expt. 4) for analysis. A completely
randomized design with four replications was used in each experiment. The
experimental unit was a single pot with three plants. Seedlings were
inoculated at the V2-V3 growth stage by spraying the adaxial and abaxial leaf
surfaces with a conidial suspension (4-6 X 104 conidia/mL), using a freon-
propelled atomizer. Inoculated plants were placed in a moist chamber for 3
days, then transferred to a greenhouse bench where they were kept at 25 to 30
C. Ratings were made 12-14 days after inoculation. Percent leaflet area
infected, using a standard area diagram, was determined on three leaflets per
plant.
Most cultivars were rated either susceptible or resistant based on the
observed reaction. Some variation was observed among susceptible lines, which
may have been the result of differences in leaf developmental stage at the

and Visiting Scientist, Plant Pathology.

time of inoculation or modifying (minor) genes for resistance. 
At least 37%
of the lines were susceptible to this isolate. Earlier MG 
lines had a higher
proportion of susceptibles. All lines observed to be resistant 
in the field
at Jay in the 1992 USDA Uniform Tests were rated resistant 
in this experiment.
Young (thought to have the Rcs
3 
gene for resistance to frogeye) showed a
susceptible reaction. The reason for this was not known.
