The 2017 Soybean Cross Reference Guide has been updated with new soybean varieties. This year’s version contains only varieties that have been commercially sold in the past seven years. Older varieties that are no longer commercially available were removed from the 2017 Guide. This is not an all-inclusive list of soybean varieties, but the best attempt to list genetically identical varieties across seed companies. The Cross Reference Guide features a list of common soybean varieties and their genetically identical commercially branded names. Please note: two varieties that are genetically the same may not perform the same side by side in the field due to differences in environmental conditions and management practices among seed increase production fields. How the seed is handled and processed between the time of harvesting in the seed increase field and planting in a grower’s field also influences overall seed quality, which in turn can affect the performance of two varieties that genetically are the same. The updated cross reference guide is available here, under the publications tab on the row crops blog, and on uaex.edu.
