Distribution of Wild Wheats and Barley

Science, 1966
If 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, 1968
An 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 ...

Wheat Pre-Breeding Using Wild Progenitors

Euphytica, 2001
To 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.

Gliadin polymorphism in wild and cultivated einkorn wheats

Theoretical and Applied Genetics, 1997
To study the relationships between different species of the Einkorn group, 408 accessions of Triticum monococcum, T. boeoticum, T. boeoticum ssp. thauodar and T. urartu were analyzed electrophoretically for their protein composition at the Gli-1 and Gli-2 loci. In all the species the range of allelic variation at the loci examined is remarkable.

Wheat phylogeny determined by RFLP analysis of nuclear DNA. 2. Wild tetraploid wheats

Theoretical and Applied Genetics, 1995
Intra- and inter-specific variations in the nuclear DNA of Triticum dicoccoides Körn. (2n = 28, genome constitution AABB) and T. araraticum Jakubz. (2n = 28, AAGG), wild species, respectively, of the Emmer and Timopheevi group, were studied by restriction fragment length polymorphism (RFLP) analysis. Total DNAs of 32 T. dicoccoides and 24 T. araraticum

High Temperature Stress in Wild Wheats and Spring Wheats

Australian Journal of Plant Physiology, 1994
The effect of high temperature stress on wild and spring wheats is reviewed. Wild wheats include species in the genera Aegilops L. and Triticum L. Species exist in a polyploid series, diploid, tetraploid and hexaploid, based on the genome formula, n = x = 7 chromosomes.

Microsatellite analysis in cultivated hexaploid wheat and wild wheat relatives.

2001
Hexaploid bread wheat contains three genomes, A, B and D with the formula AABBDD, amounting to a very large and complex total genome. Although bread wheat, Triticum aestivum (2n = 6x = 42), is one of the most extensively studied polyploid crops, the probable evolutionary history has only recently been established by studying the various wild relatives.

Wild Relatives of the Wheat Grain Proteome

Journal of Plant Biology, 2010
We 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 ...

Barban Selectivity for Wild Oat in Wheat

Weed Science, 1974
The 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.

How and When Was Wild Wheat Domesticated?

Science, 2006
Estimating 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.
