Interpretive Summary:

Technical Abstract: The objective of this test was to evaluate advanced breeding lines for agronomic performance. Two commercial lines, three East Lansing germplasm releases, and 10 experimental lines were examined. Percent sucrose was the focus of this test, and entries based on traditional East Lansing germplasm generally scored in the 15.5-16.3 percent sucrose range. Entries with some ehigh sucrose selections in their background fell into the 16-17 percent sucrose range. Hybrids of 96RR (aka EL51) and 98J19 with the higher sucrose content SP550 parent had considerably higher percent sucrose than the corresponding pollinator entries. SP550 is being considered as a source of adapted germplasm for improving sugar percentage without sacrificing resistance to Aphanomyces or Cercospora.
