Oklahoma Genetics Variety Spotlight - Gallagher and Iba

Oklahoma Genetics Variety Spotlight -  Gallagher and Iba
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 will be showcased. To hear an audio version of this story Click on the LISTEN Bar at the bottom of this story.


Today we spotlight the varieties Gallagher and Iba. They are considered sister varieties because they have one parent in common with "Duster". Both of these varieties were released at the same time and they are both considered to be dual purpose varieties that are widely adapted to Oklahoma.


Of the two varieties, Carver said Iba resembles Duster a little more as Iba acts like Duster in terms of maturity patterns and it produces kernel size similar to Duster with a 10 percent larger kernel. While Gallagher produces 15 percent larger kernel than Duster.


"It's going to be higher yielding because of that larger kernel size and its also going to have a better test weight, not that Duster has poor test weight, but Iba has a very good test history, that's something miller's of course are looking for," Carver said. "Gallagher does not produce a poor test weight, its just not as good as Iba."


Both of these varieties work well in a grazing environment, but something producers should keep in mind is that Gallagher has a earlier maturity pattern. That's important to keep in mind in putting cattle on wheat pasture.


"Gallagher is going to reach that critical reproductive stage, what we call first hallow stem stage earlier, several days earlier than Iba will," Carver said. "Iba will reach it about the same time as Duster, Gallagher can be a week earlier."


Carver said Gallagher doesn't have the same ability to recover from grazing like Iba or Duster. He said Gallagher isn't poor, its just not as good as the other varieties, so that is something producers should consider in terms of stocking rates. Carver said their research as found Gallagher has shown to produce more forage over time.


Looking forward Carver said Gallagher and Iba will both be apart of the germplasm in developing new varieties. He looks for experimental lines in the variety trials with Gallagher and Iba as parents in the next year or two. He said that's pretty amazing considering Gallagher and Iba were released in 2012. He attributes the quick turn around due to the double haploid technology that is allowing them to speed up the clock in developing new varieties.


In the 2014 OSU Wheat Variety Trial, OSU Wheat Extension Specialist Dr. Jeff Edwards said this year Gallagher was top variety in Lahoma. This year the variety was hit hard by the early April freeze in southern Oklahoma because it is a earlier maturing variety.


Gallagher is dual purpose variety with excellent fall forage production. With it being an earlier maturing variety, Edwards said producers will have to pull cattle off the wheat pasture a little earlier. He said if there is a downside to this variety it is that it won't quite handle the intense grazing as well as Duster.


As a variety, Edwards said Gallagher is designed for the central part of the state, outside of the panhandle. Gallagher offers farmers hessian fly resistance, acid soil tolerance and good disease resistance in terms leaf rust, stripe rust and soil borne mosaic virus.


Iba is a little later maturing variety. Edwards said Iba is not Hessian Fly resistant and it is not tolerant of acid soil conditions. In terms of disease resistance, Edwards said Iba is just as good as Gallagher for leaf rust and stripe rust resistance.


As a forage producer Iba is a middle of the road. Edwards said its ability to rebound after grazing is very good. One of the best strength is Iba's wide area of adaptation. Edwards said this variety will work well across the state into the Oklahoma panhandle as well into Kansas, so this variety has an extremely broad area of adaptation.


In the 2014 OSU wheat variety trials, Iba has been a real bright spot.


"It has been first or second in many trials, its been in the top grouping in almost all of the trials that we've had across the state, which speaks to its area of adaptation," Edwards said. "So it had a very good 2014 and I look for people to adopt more Iba, maybe displace some of those Duster acres where they are leaning a little bit heavier towards the grain production, it will be a very good fit on those acres."
