To: Persons interested in the performance of small grains varieties
in New York.
Enclosed are the results of our 1995 small grains regional trials and the
cumulative summaries over years. Because the rankings of the varieties and
lines often change from year to year, only the multiple year summaries should
be considered to be useful indicators of varietal performance in this region.
Reproduction of any table in this report must include the entire table unless
we approve the editing. The information herein is provided with the
understanding that no discrimination is intended and no endorsement by
Cornell University or its employees is implied.
Your comments and suggestions concerning this report are welcome. If you
would like additional information or do not wish to receive this report in
the future, feel free to call or write.
Sincerely,
Mark E. Sorrells
Professor of Plant Breeding
Testing Procedures:
In 1995, the Soft White Winter Wheat, Soft Red Winter Wheat and the Spring
Oat regional trials were grown in four locations while the Spring Barley
regionals were grown in three locations. The wheat and oat trials near
Ithaca consisted of 2 replicates while those out in the state consisted of 3
replicates. All spring barley trials had 3 replicates. All trial plots are
6 row plots 4 meters long with 18 cm between rows. Prior to harvest, the
plots are trimmed to 3 meters and harvested with a plot combine. Disease and
lodging notes were recorded on a 0 to 9 scale with 0 being the best and 9 the
poorest. All trials are planted in a randomized complete block design and
analyzed by standard ANOVA. If there are indications of within replicate
field variation a second ANOVA using a nearest-neighbor adjustment is
computed. If the coefficient of variation is significantly reduced, those
adjusted means are used for the summary.
Temperature and Precipitation - Ithaca Area:
The winter grains trials were planted between 9/19 and 10/3 and the spring
grains were planted between 4/17 and 4/28. For April through July, the
Ithaca area was 5 inches below normal rainfall and 1 degree above average
temperature. The 6 month period starting in March was the driest such period
on record (over 100 years). The below normal precipitation and above normal
temperatures severely reduced yields of spring grains.
Acknowledgments:
Our testing program depends on being able to test new varieties in the areas
where they will be grown under actual farming conditions. We gratefully
acknowledge the farmers who have provided us with a test site for our
regional trials. Without their support we would not be able to provide
accurate, unbiased test results. Also, we thank Nate Harendeen and Jim
Capron for their excellent cooperation and support over the years.
