A spike in traditional soybean varieties could be signaling a sea change in the seed industry. The University of Missouri Variety Testing Program saw a significant increase in non-glyphosate-resistant varieties in 2009, amounting to almost 15 percent of total entries.
"This is the biggest jump we've seen," said Howard Mason, MU plant sciences research associate. "The number of non-glyphosate varieties dropped most of the past decade, starting at 34 percent in 2000 and falling to a low of 1 percent in 2006."
Companies entered 61 non-glyphosate varieties and 353 Roundup-ready varieties last year as the program continued to see overall growth in participation. Howard said the shift in entries comes as farmers cope with growing weed resistance to glyphosate and high technology fees associated with Roundup-ready seed.
