Identification of QTL for Weed Suppressive Ability in the NC-Neuse x AGS 2000 Winter Wheat Population.

Herbicide resistant weeds have been a major problem plaguing the agriculture community since the early 1970’s.  Italian Ryegrass (Lolium multiflorum) is one major weed affecting the wheat growers in the United States.  With the presence of herbicide resistance, we have been forced to look at alternate forms of weed control.  The goal of this research is to identify winter wheat with weed suppressive ability.  QTL analysis was performed using a set of 139 recombinant inbred lines developed from the cross between NC-Neuse x AGS 2000 mapping population.
