Hybridization between imidazolinone-resistant wheat (Triticum aestivum L.) and jointed goatgrass (Aegilops cylindrical Host.) and selection pressure impacts on proportion of resistance alleles

Creator:

Martins, Bianca Asssis Barbosa

Abstract:

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,...

Hybridization between yellow starthistle (Centaurea solstitialis) and meadow knapweed (Centaurea x moncktonii)

Creator:

Miskella, John

Abstract:

Centaurea solstitialis L. (yellow starthistle) and C. × moncktonii Britt. (meadow knapweed) are members of the genus Centaurea in the Asteraceae family. Both species have become serious management concerns as invasive species in North America, often displacing native vegetation and costing land managers millions of dollars to eradicate. Seven plants...
