Choosing soybean varieties from yield trials

Soybean [Glycine max (L.) Merr.] variety trials are conducted in many states and results are published from several years and locations of testing. These trials usually include a large number of varieties and locations that generate a large amount of agronomic data. Use of this information by growers and agricultural advisors to choose high-yielding varieties is a difficult task. This study was conducted to determine which combination of locations and years was best to identify good-yielding soybean varieties. We analyzed test results from soybean variety trials conducted by the Minnesota Soybean Breeding Project at three locations from 1980 through 1989 (...)
