“…The most notable resynthesized crops have been the synthetic hexaploid wheat, produced by crossing durum wheat (2n = 28, AB genomes) with Aegilops tauschii (2n = 14, D genome). These hybrids have been used as an intermediary for transferring resistance/tolerance to many biotic and abiotic stresses as well as adding substantial variability for morphophysiological and reproductive traits to wheat (Fernandes et al 2000;del Blanco et al 2001 and references therein). A major program was developed at CIMMYT to create more than 1,000 synthetic wheats that could be used to broaden the genetic diversity of the modern wheat.…”

“…Pertencente à família Poaceae se originou do cruzamento de outras plantas silvestres que existiam nas proximidades dos rios Tigre e Eufrates (Brammer, 2000;Moraes-Fernandes et al, 2000).…”

“…Além disso, A. tauschii é uma espécie a que se tem dado particular atenção por produzir hexaplóides sintéticos (AABBDD), obtidos mediante cruzamentos interespecíficos diretos, podendo ser útil na transferência de genes de interesse (Moraes-Fernandes et al, 2000;Aguilar-Rincón et al, 2000). Assim, o objetivo desse trabalho foi avaliar a resistência à ferrugem da folha em acessos de A. tauschii para posteriores cruzamentos em programas de melhoramento, a fim de incorporar esta resistência em cultivares comerciais.…”
