“…In hexaploid wheat, cross resistance to chiortoluron and metoxuron has been shown to be a property of the Sul locus on chromosome 6B (Snape et a!., 1990). As individual families of T dicoccoides show similar cross resistance it is likely to be due to this same gene.…”

The responses of wild populations of emmer wheat (Triticum dicoccoides), from different ecogeographical areas of Israel, to three herbicides, difenzoquat, chiortoluron and metoxuron, commonly used on cultivated wheats, were studied. Although cultivated wheats are polymorphic for a response to difenzoquat, all families of all populations of the wild species were resistant. The species was, however, polymorphic for response to both chiortoluron and metoxuron. In addition, there appeared to be differentiation between populations in the frequencies of resistant and susceptible morphs for these herbicides. There was also a close correspondence between the responses of individual families to chiortoluron and metoxuron, which suggests a common genetic control. The implications of these findings for understanding the evolution of herbicide resistance, and for developing strategies for breeding for resistance in the cultivated species are discussed.

“…Historically, few HRCs have been developed with traditional plant-breeding approaches Beversdorf and Kott, 1987;Snape et al, 1987Snape et al, , 1990Snape et al, , 1991Van Heile et al, 1970). This is probably due to the length of time needed to develop resistant cultivars relative to the patent life of a herbicide.…”

This chapter reviews information about how crop plants resist herbicides and how resistance is selected for in plants and surveys specific herbicide-resistant crops by chemical family. The discussion in the chapter includes HRCs derived from both traditional and biotechnological selection methodologies. Plants avoid the effects of herbicides they encounter by several different mechanisms. These mechanisms can be grouped into two categories: those that exclude the herbicide molecule from the site in the plant where they induce the toxic response and those that render the specific site of herbicide action resistant to the chemical. The chapter presents herbicide-resistant crops by the herbicide chemical family-such as, triazine, acetolactate synthatase, acetyl-CoA carboxylase, glyphosate, bromoxynil, phenoxycarboxylic acids, and glufosinate. Resistant crops are listed in the chapter regardless of whether they have been commercialized or were developed for experimental purposes only, and are provided regardless of their "success" as resistant plants.
