Michael Stamm's Research


Torrington (New!)

Torrington was released in 2016. It is named for the hometown of Dr. Charlie Rife, former canola breeder at Kansas State University and developer of the varieties Wichita and Sumner. Torrington is a conventional variety that shows improved winter survival over commercial checks in Kansas and Oklahoma. From 2014 to 2015, Torrington averaged 7% greater survival than Riley and 18% greater survival than Wichita.


Griffin (PDF) was released in 2011 and is the first cultivar designated for dual-purpose use. Griffin shows better winter survival following the suggested grazing period. A prostrate growth habit allows Griffin to exhibit greater winter survival. Although grazing reduces final grain yield, Griffin’s yield is reduced less than other cultivars.


Riley (PDF) was released in 2010. This is the first cultivar released by the program with oil content greater than 40%. Riley has averaged over 200 lb/acre greater yield than Wichita.

Roundup Ready® cultivars released by the program are currently marketed by Monsanto Company and CROPLAN by WinField. Please check company websites for details on these cultivars.
