"They are protected from leaf rust by genes derived from a goat grass collected in Iran," he says.
In the same issue of the Journal of Agricultural and Food Chemistry, Carol Mallory-Smith of Oregon State University in Corvallis chronicles the emergence of herbicide-resistant hybrid goat grass. It is evolving the ability to tolerate the herbicide imazamox in fields planted with wheat that has been bred to be immune to the chemical.
The grasses of "Alopecurus-myosuroides" with the density of (10/[m.sup.2]), goat grass "Aegilops cylindrical" with the density of (1-1.5/[m.sup.2]) and, presence of 15 wild oat (Avena fatua) with the density of (15/[m.sup.2] in fertilizer level of 75 kg/ha (N) decreased wheat yield as much as 4.87 (%), 3-30 (%) and 30 (%), respectively [11,19,30].
"But the problem is that GM wheat can cross-pollinate [mate] with the closely related weed, jointed goat grass." The results could prove disastrous: If the weed incorporates GM wheat's pesticide-resistant gene into its own DNA, making it immune to Roundup, the weed could potentially overrun healthy wheat crops.
