Competition of Wild Oat in Wheat and Barley
Weed Science, 1968Wild oat (Avena fatua L.) competition increased the losses in yield of both wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) with increased densities of seedlings. At Fargo in 1965, wild oat densities of 70 and 160 seedlings/sq yd reduced the wheat yield 22.1% and 39.1%, respectively, compared to the wild oat-free check.

How and When Was Wild Wheat Domesticated?
Science, 2006Estimating the time span of plant domestication is fundamental to understanding and reconstructing the cultural processes underlying the “Neolithic Revolution.” In their Brevia “How fast was wild wheat domesticated?” (31 Mar., p. [1886][1]), K. Tanno and G.

Wheat Pre-Breeding Using Wild Progenitors
Euphytica, 2001To facilitate the use of wheat wild relatives in conventional breedingprograms, a wheat pre-breeding activity started at ICARDA in 1994/1995season. Preliminary results of gene introgression from wild diploidprogenitors, Triticum urartu, T. baeoticum, Aegilops speltoides andAe. tauschii and tetraploid T. dicoccoides are described.

Wild Relatives of the Wheat Grain Proteome
Journal of Plant Biology, 2010We applied proteomics analysis to generate a map of the wild relatives of wheat grain proteins. These differentially expressed proteins are potentially involved in metabolism, stress responses, and other biological activities. Using two-dimensional electrophoresis, we detected 119, 134, and 193 reproducible spots on gels loaded with protein samples ...

Distribution of wild wheats and barley.
Science (New York, N.Y.), 2010If we accept the evidence at face value, we are led to conclude that emmer was probably domesticated in the upper Jordan watershed and that einkorn was domesticated in southeast Turkey. Barley could have been domesticated almost anywhere within the arc bordering the fertile crescent.

Competition Between Wheat and Wild Buckwheat
Weed Science, 1968An experiment was conducted comparing wheat (Triticum aestivum L., var. Pembina) and wild buckwheat (Polygonum convolvulus L.) grown alone in pots, in full competition, and in root competition at three levels each of soil fertility and soil moisture, and harvested at three dates.Wheat was a better competitor than wild buckwheat when considering dry ...

Barban Selectivity for Wild Oat in Wheat
Weed Science, 1974The response of wheat (Triticum aestivum L.) and wild oat (Avena fatua L.) to barban (4-chloro-2-butynyl-m-chlorocarbanilate) was studied as influenced by plant morphology and air temperature after application. Growth of wheat and wild oat seedlings was reduced by barban at 0.3 μg and 0.6 μg applied to the first node, respectively.
