Oklahoma Genetics Variety Spotlight - Doublestop CL PlusWed, 03 Sep 2014 16:59:26 CDT
As wheat planting plans come into focus, the Radio Oklahoma Ag Network and Oklahoma Farm Report.com want to help you consider how the genetics developed by Dr. Brett Carver and his Wheat Improvement Team may fit into your wheat production system. A profile of several of the major wheat varieties that have come from the Oklahoma State University program have been showcased.

Today we spotlight Doublestop CL Plus - a two gene Clearfield wheat variety that offers improved control of problem weeds such as feral rye and jointed goatgrass. Carver said Doublestop is a definite improvement over Centerfield a single gene variety developed by OSU that offered herbicide tolerance. Doublestop offers excellent test weight in a late maturing wheat variety that has good protein content and quality.
"Doublestop raises the bar in terms of yield potential, disease resistance, all of those things we looking for in a non-clearfield variety," Carver said. "I feel Doublestop was a variety that they would have released even without the herbicide resistance, it's that strong."
With the dry growing season from the fall of 2013 to the spring of 2014, Doublestop didn't perform to its true potential. Carver said the variety has been planted in fields since 2008, but it struggled in the exceptionally dry environment this year. Carver said we just didn't have the environment to see that yield benefit and if you don't have the environment for those genes to be seen, then its almost like they are not even there.
Doublestop is known as a very rugged variety with its ability to perform across a wide range of environments, its tolerance of acid soil types and its ability to control weeds
"It takes a lot of abuse, it going to need it in putting it out in a field to control rye and rye grass," Carver said. "It covers the ground very quickly and it gives us the type of canopy to fight weeds."
In looking at different varieties, OSU Wheat Extension Specialist Dr. Jeff Edwards said Doublestop offers farmers the opportunity to clean up some of those problem acres with feral rye.
"If we don't get that feral rye under control we're not going to improve wheat yields and really you have two options," Edwards said. "You can grow winter canola or you can grow a two-gene clearfield wheat."
Double Stop is Oklahoma bred and its a good fit for all of Oklahoma and its also adapted to the panhandle of Texas, Kansas and the eastern plains of Colorado. Edwards said that broad area of adaptation is comparable to the variety Iba.
In the 2014 OSU wheat variety trial, Edwards said Doublestop finished near the middle of the pack.
"I think a lot of that has to do with the later maturity and simply running out of moisture and trying to conduct grainfill during the hottest time of year," Edwards said. "In a more normal year where maybe we have a little bit more stored soil moisture hopefully I would expect it to perform back where it did in 2013 near the top of many of our trials."
