Technical Abstract: This experiment was designed to evaluate performance of 24 entries for the standard agronomic parameters, and smoothroot score as a surrogate measure for low soil tare. The properties of nine breeding germplasm entries, agronomically evaluated for the first time, indicate the recent emphasis of the sugarbeet breeding program at East Lansing. All nine new entries are high to moderate for smoothroot as well as for resistance to Cercospora an Aphanomyces. Four of the nine are monogerm with enhanced CMS-maintainer frequency, moderate Rhizoctonia resistance, and/or improved sucrose percent, depending on the entry. The other five new entries carry deliberately introduced recessive alleles for monogerm or CMS-maintenance that can be recovered in fixed form in current or future generations. Emphasis on disease resistance and higher sucrose percentage will continue and complement the easily selectable smoothroot characteristic.
