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.

Planted April 22, 1999; Harvested October 4-5, 1999.

1 All entries are commercial seed obtained locally.
2 Root yields have been tared 5%.
3 Curly 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.
4 Entered in 1999 rhizomania variety test.
