Interpretive Summary:

Technical Abstract: This experiment was designed to evaluate performance for the standard agronomic parameters as well as suture prominence score. Tested germplasm included three commercial hybrid varieties, five East Lansing ARS smoothroot releases, and four prospective East Lansing ARS smoothroot releases. Releases derived from the East Lansing ARS breeding program combine Eastern US smoothroot sugarbeet germplasm with high sucrose percentage germplasm lacking tolerance to diseases in the Great Lakes production area. Recoverable White Sugar per Acre (RWSA) performance of the three commercial hybrids was highest, and the extremely smoothroot entries SR87 and SR93 were among the lowest, consistent with past performances. In general, the historical pattern of inverse relationship between sucrose percentage and root smoothness is seen in this test, although SR95 and a prospective release (97HS21-7) have root smoothness nearly as great as released germplasms SR87 and SR93 but significantly higher sucrose content.
