“Joe” is a new hard white winter wheat variety released this summer by the Kansas Agricultural Experiment Station. This variety was developed at K-State’s Agricultural Research Center-Hays from a cross made by Joe Martin, retired wheat breeder at ARC-Hays. Joe was in the 2015 K-State Performance Tests as experimental number KS11HW39-5-4. Its pedigree includes two white experimental lines, KS04HW10-3 and KS04HW119-3.
Yield record: Joe has yielded very well in western Kansas. It has shown a significant increase in yield potential over currently grown varieties. Averaged over three years (2013 to 2015) of dryland testing across western Kansas, yields of this variety were about 16% higher than Danby and about 33% higher than TAM 111. Danby and TAM 111 are two of the most adapted hard white and hard red wheat varieties, respectively, in western Kansas. In 2015 Kansas Wheat Performance Test, the average yield of Joe ranked No. 1 across dryland testing sites in western Kansas and was at least 5% higher than all other varieties in the trials. Joe has been tested under irrigation in Colby, Kansas, for the last three years. Yields averaged 103.7 bu/acre, which was about 19% higher than Danby and 27% higher than TAM 111. Joe was also tested in 2015 Colorado Dryland Wheat Performance Test and ranked No. 1 with an average yield of 81.3 bu/acre across the nine testing sites.
- Disease resistance: Joe has very good resistance to wheat streak mosaic virus, stripe rust, and leaf rust.
- Maturity: Medium late
- Straw strength: Above average
- Height: Medium tall
- Winterhardiness: Good
- Milling and baking quality: Good
- Pre-harvest sprouting tolerance: Moderately susceptible
- Area of adaptation: western Kansas and eastern Colorado
Registered seed of Joe will be available in the fall of 2016. It is an open-market hard white winter wheat, and like all white wheat varieties will need to be kept separate from hard red winter varieties through the production, harvesting, and marketing chain.
