The structure of wild and domesticated emmer wheat populations, gene flow between them, and the site of emmer domestication

Theoretical and Applied Genetics, 2007
The domestication of emmer wheat (Triticum turgidum spp. dicoccoides, genomes BBAA) was one of the key events during the emergence of agriculture in southwestern Asia, and was a prerequisite for the evolution of durum and common wheat. Single- and multilocus genotypes based on restriction fragment length polymorphism at 131 loci were analyzed to ...

A CNL protein in wild emmer wheat confers powdery mildew resistance

New Phytologist, 2020
Summary Powdery mildew, a fungal disease caused by Blumeria graminis f. sp. tritici (Bgt), has a serious impact on wheat production. Loss of resistance in cultivars prompts a continuing search for new sources of resistance. Wild emmer wheat (Triticum turgidum ssp.

Chromosome translocations in wild populations of tetraploid emmer wheat in Israel and Turkey

Theoretical and Applied Genetics, 1995
Translocation frequencies (as compared to the standard chromosome arrangement typified by that in 'Chinese Spring') in 9 or more genotypes from each of 15 populations of Triticum dicoccoides in Israel were determined. Data also were obtained from 2 genotypes of the southernmost population (Jaba).

Herbicide response polymorphisms in wild emmer wheat: ecological and isozyme correlations

Theoretical and Applied Genetics, 1992
We demonstrate that the scores and frequencies of chlortoluron (CT) and metoxuron (MX) resistance and susceptible phenotypes of wild emmer wheat, Triticum dicoccoides, are correlated with ecological factors and allozyme markers. Some isozyme markers located on chromosome 6B (e.g.

Wild emmer contribution in wheat domestication and adaptation to new environments

2023
Abstract Wheat is a staple crop, and its production is heavily threatened by climate change and soil erosion. Breeding programmes commonly rely on the wild progenitor, wild emmer wheat, Triticum turgidum subsp.

Geographic distribution and domestication of wild emmer wheat (Triticum dicoccoides)

Genetic Resources and Crop Evolution, 2010
The transition from hunting and gathering to agriculture had revolutionary consequences for the development of human societies. Crops such as wheat, barley, lentil, pea and chickpea played a crucial role in the establishment of complex civilizations in south west Asia.

Evolution and Adaptation of Wild Emmer Wheat Populations to Biotic and Abiotic Stresses

Annual Review of Phytopathology, 2016
The genetic bottlenecks associated with plant domestication and subsequent selection in man-made agroecosystems have limited the genetic diversity of modern crops and increased their vulnerability to environmental stresses. Wild emmer wheat, the tetraploid progenitor of domesticated wheat, distributed along a wide range of ecogeographical conditions in

Genetic diversity of wild emmer wheat in Israel and Turkey

Theoretical and Applied Genetics, 1989
Allozyme variation in the tetraploid wild emmer wheat, Triticum dicoccoides, the progenitor of all cultivated wheats, was studied for the proteins encoded by 42 gene loci in 1815 plants representing 37 populations - 33 from Israel and 4 from Turkey - sampled in 33 localities from 1979 to 1987.

THE CONTRIBUTION OF THE DISCOVERY OF WILD EMMER TO AN UNDERSTANDING OF WHEAT EVOLUTION AND DOMESTICATION AND TO WHEAT IMPROVEMENT

Israel Journal of Plant Sciences, 2001
Wild emmer wheat, Triticum turgidum ssp. dicoccoides, the progenitor of most domesticated wheats, was discovered by Aaron Aaronsohn in 1906 in the Levant. The contribution of this discovery to the study of the cytogenetic structure and evolution of the wheats, to an understanding of the processes and site of their domestication and evolution under ...

Reaction of Wild Emmer Wheat Accessions to Fusarium Head Blight

Crop Science, 2007
ABSTRACTFusarium head blight (FHB), caused mainly by Fusarium graminearum Schwabe, is a serious disease of wheat (Triticum spp.) worldwide. Host resistance has proven the most effective method of controlling FHB in common wheat (T. aestivum L., 2n = 6x = 42, genomes AABBDD). Progress in breeding for FHB resistance in durum wheat (T. turgidum L.
