Interpretive Summary: Wheat producers have been plagued by weedy grass species which compete with wheat for moisture and mineral resources. Two such species, feral rye and jointed goat-grass, are closely related to wheat. The similar genetic makeup of these grasses long prevented the development of specific herbicides capable of killing them but sparing the wheat. Recently, however, scientists in private industry identified mutant genes capable of conferring resistance to a class of herbicides known as imadazolines. Use of these mutant genes, dubbed “Clearfield technology” allows a non-transgenic approach to the control of goat-grasses, feral rye and other grassy weeds in wheat fields, with a concomitant improvement in wheat grain yield and quality of harvested grain. NH03614 CL is a new hard red winter wheat variety that combines the Clearfield technology with high grain yield potential, resistance to some pathogens, and acceptable breadmaking quality.

Technical Abstract: 'NH03614 CL' (PI 653833) hard red winter wheat (Triticum aestivum L.) was developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA-ARS and released in 2008 by the developing institutions and the South Dakota Experiment Station and the Wyoming Agricultural Experiment Station.. In addition to researchers at the releasing institutions, USDA-ARS researchers at Manhattan, KS, and St. Paul, MN, participated in the development of NH03614 CL. NH03614 CL was selected from the cross Wesley sib//Millennium sib/Above sib that was made in the spring of 1997. NH03614 CL was selected as an F3:4 line (F3-derived line in the F4 generation) in 2001, and in 2003 was assigned experimental line number NH03164. NH03614 CL was released primarily for its herbicide tolerance to imadazoline compounds which control many previously difficult to control weeds in wheat production systems, and for its superior adaptation to rainfed wheat production systems in Nebraska, Wyoming, South Dakota, and counties in adjacent states. NH03614 CL will be marketed under the name Husker Genetics Brand Settler CL.
