0PI 668090'SY Clearstone 2CL'Triticum aestivum L. subsp. aestivum Montana, United StatesPVPONot Available2013DEVELOPED2012Cultivar`SY Clearstone 2CL? is a two-gene Clearfield backcross-derivative of `Yellowstone? hard red winter wheat. The line contains the AHAS1LD gene (FS2 via MTCL01158) and the AHAS1LB gene (via Teal 11A) which confer tolerance to imidazolinone herbicide in wheat. SY Clearstone 2CL is similar to its recurrent parent Yellowstone for height, maturity, stripe rust resistance, end-use qualities, and most agronomic and production characteristics including grain yield. SY Clearstone 2CL is susceptible to Russian wheat aphid (Diuraphis noxia Mordvilko), wheat stem sawfly (Cephus cinctus Norton), and Hessian fly [Mayetiola destructor (Say)]. SY Clearstone 2CL is resistant to stripe rust (Puccinia striiformis), moderately resistant to stem rust (Puccinia graminis), and susceptible to leaf rust (Puccinia triticina).1909913PI 668090
