EVALUATION OF TRANSGENIC SUGARBEETS IN THE MONDAK REGION
Joyce Eckhoff, EARC Agronomist
Transgenic sugarbeets are sugarbeets that have been
genetically altered through the use of recombinant DNA. Two types of transgenic beets were
tested at the MSU Eastern Ag Research Center in 1997 and 1998, Liberty-Link (LL) which
confers resistance to the general herbicide Liberty, and Roundup-Ready (RR), which confers
resistance to the herbicide Roundup.
Planted: May 5, 1998 Six-row plots, 150 seed/row,
rows 30 feet long with 24 inches between rows.
First application at the two-leaf stage: May 29,
1998; Liberty, 2.5 pt/ac; RoundUp 1.5 pt/ac; Betamix 1.17pt/ac + Poast 1 pt/ac
Trimmed and thinned: June 5, 1998
Second application at the six-leaf stage: June
12, 1998; Liberty, 2.5 pt/ac; RoundUp 1.5 pt/ac; Betamix 1.5 pt/ac
Sugarbeets with the LL gene that were sprayed with
Liberty produced about 1270 lbs of sugar per acre more than the same variety without the
LL gene that were sprayed with Betamix. The Liberty-Link sugarbeets also had less loss to
molasses than conventional sugarbeets, resulting in a greater percent extraction.
Sugarbeets with the RR gene that were sprayed with Roundup produced about 1200 lbs of
sugar per acre more than the same variety without the RR gene. These data are similar to
data produced in 1997, and indicate that the herbicide resistant genes did not reduce
yield or quality of the sugarbeet varieties tested.
