Jointed goatgrass (Aegilops cylindrica Host; 2n=4x=28; CCDD) is an
agriculturally important species both as a weed and as a genetic resource for
wheat (Triticum aestivum L.; 2n=6x=42; AABBDD) improvement. In order to
better understand the evolution of this species, the diversity of Ae. cylindrica
was evaluated along with its progenitors,...
Jointed goatgrass (Aegilops cylindrica Host.) is a winter annual grass weed that was introduced into the United States in the late 1800s. It is
found throughout the continental United States and is most common in the winter wheat (Triticum aestivum L.) production areas of the Pacific Northwest and central Great...
Imazamox-resistant wheat (Clearfield®) cultivars carry the Imi1 gene, which confers resistance to the imidazolinone (IMI) herbicide imazamox. Imazamox provides selective control of jointed goatgrass and other weeds in IMI-resistant wheat. Imi1 gene flow between IMI-resistant wheat and jointed goatgrass may occur via hybridization and backcross events. In 2009 and 2010,...
Jointed goatgrass (Aegilops cylindrica Host.) is a serious weed problem in wheat
(Triticum aestivum L.) production in the United States. Studies were conducted to
determine the outcrossing rate, competitive ability, and effectiveness of certain control
practices on jointed goatgrass. A field study was conducted over two years at four
Jointed goatgrass (Aegilops cylindrica Host) infestations in winter wheat
(Triticum aestivum L.) production regions of the central and western USA result in severe
economic losses in the wheat market. Field and greenhouse studies were conducted to
determine the vernalization requirements of winter wheat, spring wheat, jointed
goatgrass, and wheat by...
