Information about dry bean variety performance can be accessed on the Web at www.ag.ndsu.edu/varietytrials/, the site with all variety trial data from all NDSU Research Extension Centers for all crops.

Information contained in this article is based on research conducted by the following North Dakota Agricultural Experiment Station scientist and authors: Blaine Schatz, Walter Albus and Leonard, Carrington Research Extension Center Irrigation site Oakes; Bryan Hanson and Richard Wilhelmi, Langdon Research Extension Center; Mark Halverson, Angela Sebelius and James Tarasenko, North Central Research Extension Center, Minot.

The agronomic data presented in this article are from replicated research plots using experimental designs that enable the use of statistical analysis.

The LSD (least significant difference) numbers beneath the columns in the tables are derived from the statistical analyses and only apply to the numbers in the column in which they appear. If the difference between two varieties exceeds the LSD value, it means that with 95 percent probability, the higher-yielding variety has a significant yield advantage. If the difference between two varieties is less than the LSD value, then the variety yields are considered similar. 

The abbreviation NS is used to indicate no significant difference for that trait among any of the varieties. The CV is a measure of variability in the trial.

The CV stands for coefficient of variation and is expressed as a percentage. Large CVs mean a large amount of variation that could not be attributed to differences in the varieties. In the tables, the “mean” indicates the average of the observations in the column. Only compare values within the table and look for trends for the desired trait among different experimental sites and years.

In the tables, the dry bean varieties are arranged in alphabetical order within market class. Footnotes provide more detailed information about data in the table under which they appear. Characteristics to evaluate for selecting a dry bean variety include marketing class, yield potential in your area, test weight, reaction to problematic diseases and maturity date.

When selecting a high-yielding and good-quality variety, use data that summarizes several years and locations. Choose a high-quality variety that, on average, performs the best at multiple locations near your farm during several years. Summary tables provide information about the origin of the variety, relative maturity, plant type and disease tolerance, if known.
