K-State releases three new wheat varieties

A stand of wheat grows in a Kansas State test plot. The university is introducing three new varieties this year, which will be available commercially in 2020.

Kansas State University recently three new wheat varieties, which are available to Certified Seed growers this fall and will be available to farmers in fall 2020.

The new releases include two hard red winter wheat varieties – KS Western Star and KS Dallas – and one hard white wheat, KS Silverado. They were all developed at the K-State Agricultural Research Center in Hays, Kansas.

The wheat breeding program at Kansas State University, with locations in Manhattan and Hays, receives funding from the Kansas Wheat Commission through the two-cent wheat checkoff. It aims to give producers ever-improving options of wheat varieties to plant. Whether it’s improved resistance or increased yields, wheat breeders are creating varieties that meet producers’ changing needs.

KS Western Star

KS Western Star was named after the Western Star Milling Company in Salina, Kansas. It is adapted to central and western Kansas, eastern Colorado, northwestern Oklahoma and southwestern Nebraska.

KS Western Star is a medium maturity and medium tall statured variety. It had greater yields than any other hard red winter wheat varieties in the KIN tests in 2017 and 2018. On average over the two years, it yielded more than any common check varieties, including Joe.

KS Western Star has resistances to stripe rust, leaf rust and soilborne mosaic virus. It has very good straw strength and grain shattering resistance along with good milling and baking qualities, according to K-State researchers. The variety also has good pre-harvest sprouting resistance.

It tolerates drought conditions well and has high yield potential. While it is susceptible to Hessian fly and wheat streak mosaic virus, it has wheat curl mite resistance and intermediate resistance to Triticum mosaic virus.

KS Dallas

KS Dallas was named after retired plant pathologist Dr. Dallas Seifers, who worked at the K-State Agricultural Research Center in Hays and helped to develop the WSM2 gene found in the varieties KS Dallas and Joe. It is adapted to the western half of Kansas, eastern Colorado, northwestern Oklahoma, the Texas panhandle and southwestern Nebraska.

KS Dallas is a medium maturity and medium height variety. It performed well in western Kansas in 2017 and 2018. KS Dallas has a strong disease package with wheat streak mosaic virus resistance up to 70 degrees F, which is three degrees higher than those resistant varieties with WSM2, such as Joe and Oakley CL.

It has moderate resistance to stripe rust and good resistance to leaf rust and stem rust. It is susceptible to soil-borne mosaic virus and moderately susceptible to Hessian fly. It has good shattering resistance and pre-harvest sprouting resistance. Its straw strength is about average, which is similar to T158.

KS Dallas has good milling and baking qualities. In general, it has good flour yield, high water absorption and good mixing tolerance.

KS Silverado

KS Silverado is a hard white wheat with medium-early maturity and medium-short height. It is adapted to central and western Kansas. It has very good pre-harvest sprouting resistance. Its shattering resistance is moderate, which is similar to Joe. Its straw strength is very good.

KS Silverado showed resistance to wheat streak mosaic virus in inoculated tests in the growth chamber at 64 degrees F. It has moderate to intermediate resistance to stripe and stem rusts, and wheat blast. It is resistant to leaf rust, Hessian fly, and soil-borne mosaic virus. It is moderately susceptible to fusarium head blight, barley yellow dwarf virus and powdery mildew. Preliminary data showed that it has intermediate resistance to Triticum mosaic virus.
