Oklahoma Genetics Variety Spotlight - GarrisonWed, 06 Aug 2014 19:07:14 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 will be offered for the next few weeks. To hear an audio version of this story Click on the LISTEN Bar at the bottom of this story. Today, we showcase the variety Garrison.
Garrison has a unique history. Carver said Garrison's parentage had green bug resistance, was a hard white wheat variety and offered higher test weights. Carver said in the end Garrison didn't get resistance to green bug, it turned to be a hard red wheat, but it also had a pretty good combination of disease resistance.
"That was motivation behind naming this variety Garrison, because we felt there was a Garrison of protection provided to a lot of diseases," Carver said. "One of those diseases happened to be stripe rust."
OSU began testing Garrison in 2005 and it was released in 2011. In 2005 Carver said that was the time when stripe rust was becoming an issue in Oklahoma. Up until the time it was released Garrision was tested against different races of the stripe rust pathogen. Garrison was providing good resistance to multiple races of stripe rust. The year after Garrison was released a new form of stripe rust arrived and that race could defeat the resistance present in Garrison.
"We don't know which one is going to show up on our door step next year, if it comes in next year," Carver said. "If it was say the 2010 race that appeared, Garrison will be just fine, but if its the 2012 race, either whole or in part, farmers need to know that and they need to be ready to apply a fungicide."
Garrison also offers resistance to tan spot and some resistance to head scab. However Garrison will be at risk where Hessian Fly is an issue.
The primary adaptation area for Garrison includes all of Oklahoma, into Kansas, eastern Colorado, southern Nebraska and west into the Texas High Plains. Garrison is a good grazing wheat and has a lot of the same characteristics that are valued in the variety Endurance, but with better test weights.
In the 2014 OSU Wheat Variety Trial, OSU Wheat Extension Specialist Dr. Jeff Edwards said Garrison had a mixed year.
"In 2014 Garrrison took it on the chin at a lot of locations because of the limited soil moisture," Edwards said. "It's a later maturing variety.... and because of that it ran out of moisture and was maturing and finishing grain fill right about the time that temperate was ramping up and that really hurt our later maturing varieties this year like Garrison and even to some extent Double Stop."
Edwards said farmers should consider Garrison especially if they need a variety that can handle acid soil tolerance and while delivering better test weights than a older variety like Endurance.
