INTRODUCTION TO VARIETY TESTS
The purpose of this publication is to provide performance data of the many soybean varieties offered for
sale in Virginia. These data should be of benefit to producers and agribusinesses in making selections of
varieties for their use. It is realized that not all varieties that are offered for sale in Virginia are included in
these tests. There is no implication that varieties not included are inferior in any way, but only that they have
not been tested. The private varieties that have been evaluated in these tests were submitted for testing by
commercial seed companies.
Variety evaluations were conducted under full-season and double cop conditions at Blackstone,
Chesapeake, Orange, Painter, Suffolk, and/or Warsaw. All double-crop tests were no-till planted following
small grains. Due to the number of entries, it was necessary to separate the varieties by maturity in all
locations.
Virginia experienced one of the worst seasons on record. Drought plagued most of the state during the
growing season and rainfall was nearly continuous during harvest season. The dry summer and wet fall led
to low yields and poor seed quality. Even so, yields at two of our variety test locations averaged over 50
bushels due to good soils and timely rains. Phomopsis seed decay (represented by seed quality (SQ)
ratings) and purple seed stain (PSS) were much higher than normal and is reflected in tables 3-13. Due to
very low yields and data variability, the Blackstone full-season and double-crop tests, the Orange double-
crop maturity group 3 test, and the Chesapeake double-crop test will not be published. However, data for
these locations can be obtained from the authors upon request.
INTERPRETING THE RESULTS
Tables 1 and 2 are yield summaries over all locations. Past analysis of test data indicated that variety
selection should be made from multiple years and sites. More locations result in more reliable information.
However, average yields over locations should not be used to select the highest yielding variety unless all
varieties are tested in all locations because data will be skewed to those varieties that are tested in the
highest yielding locations. Therefore, relative yield is a better method of comparing varieties over
locations. Relative yield is calculated by dividing the yield of a variety by the average yield of all varieties
within the same maturity group at that location. A variety with a relative yield of 105 was 5% above the
average of all varieties at that location. Relative yield is not an actual yield, but a value that is relative to
all other yield values at that location. Varieties are ranked by relative yield in descending order.
Tables 3 through 13 contain detailed yield and other information from each location. The highest
average yielding varieties are listed first in each table. It is not statistically correct to compare varieties
from different maturity groups. However, it is recommended that producers select two to three of the
highest yielding varieties from each maturity group adapted to his region in order to spread out harvesting
time and yield risks associated with timing of summer rainfall patterns. Because of year-to-year variability
in variety performance it is suggested that data for varieties with less than three locations or years testing
be considered preliminary. The average performance of a variety over multiple environments is more
reliable than its performance in one test. Multiple-year data can be obtained from the authors. Many of the
new varieties, which do not have two-year averages, are excellent and will probably earn a share of the
Virginia soybean acreage. Other traits are also shown in the tables (maturity, lodging, height, seed quality,
purple stain, seed size) because each producer emphasizes certain of these traits or a combination of them
when selecting varieties for his farm. After examining these results, the producer may want to plant
limited quantities of several new better performing varieties to observe how they perform on his farm and
under his management conditions.
Within maturity groups at each location, an LSD (least significant difference) was calculated. The
LSD is a statistical test calculated at the 10% probability level to aid the reader in comparing the yield
differences among varieties within a particular maturity group. When two entries are compared and the
difference between them is greater than the calculated LSD value, the varieties are considered to be
significantly different. The "NS" designation indicates that there were no significant differences for yield
among the varieties within that maturity group. The coefficient of variation (CV) is a relative measure of
variation and is an indicator of the degree of precision associated with the test. For soybean variety
evaluation tests, CV values less than 15% indicates that the precision of the test was good in distinguishing
3
differences between varieties.

METHODS AND DEFINITIONS
The variety test was evaluated in a randomized complete block design and replicated three times. All
tests were maintained weed free with herbicides and hand weeding. Row widths, number of rows planted
and harvested, and length of row harvested are shown on the production information page. Harvest was
conduction as near to the date of first harvest maturity as work schedules and weather would permit.
Fertilizer was applied according to VPI & SU soil test recommendations.
Seeding Rates (seeds/acre):
Maturity Group Full Season Double-Crop
III 180,000 240,000
IV 180,000 240,000
V 180,000 240,000
VI 180,000 --
Maturity was taken at the date when 95% of the pods turned brown (R8). Detailed maturity date
information was not taken at the Blackstone and Painter due to greater travel distance from the
TAREC. Full-season maturity ratings were not taken on a regular basis at the Orange double-crop
location. Therefore, data at these locations should not be used to compare varieties within a test.
Lodging notes are recorded on a scale of 1 to 5 according to the following criteria:
1.0 - almost all plants erect
2.0 - either all plants leaning slightly, or a few plants down
3.0 - either all plants leaning moderately (45o angle), or 25 to 50% down
4.0 - either all plants leaning considerably, or 50 to 80% down
5.0 - all plants down
Plant Height is determined as the average length of plants in a plot from the ground to the
uppermost node of the plant at maturity.
Purple Seed Stain (PSS) is the percentage of seed from a 100-seed sample that are affected with
that disease.
Seed Quality (SQ) is rated from 1 to 5 according to the following scale:
1.0 = very good; 2.0 = good; 3.0 = fair; 4.0 = poor; 5.0 = very poor.
Seed quality ratings are a good representation of Phomopsis seed decay.
Seed Size (SS) is obtained from the weight of a 100-seed sample and is transformed to number of
seed per pound.
Yields were collected with a small-plot combine equipped with scales and moisture tester. Yields
were adjusted to 13% moisture. A bushel weight of 60 pounds (at 13% moisture) was used to
determine bushel-per-acre (BU/AC) yield.
