When comparing yields or sugars of two varieties, the values must differ by a value equal to or greater than the LSD given at the bottom of each column.  If they do not, then they were probably not different in this test.

1All entries are commercial seed obtained locally.
  Locations:  1999: Aberdeen, Idaho; Jerome County, Idaho; Ontario, Oregon.
                       2000: Aberdeen, Idaho; Cassia County, Idaho; Ontario, Oregon.
2Root yields have been tared 5%.
3Curly Top Ratings: 0 = no curly top symptoms; 9 = plants killed.  To calculate and compare the average
   curly top resistance of two or more varieties, use only those years data in which the compared 
   varieties all have ratings.  The Beet Sugar Development Foundation's 2000 Curly Top test results are 
   omitted due to inconsistent ratings; a result of severe stand loss at cultivation.
4Entered as a rhizomania resistant variety.
