1. Molecular cytogenetic characterization of parental genomes in the partial amphidiploid Triticum aestivum x Thinopyrum ponticum
The wheat line PF 839197 and six hybrid derivatives from a cross between PF 839197 and Thinopyrum ponticum were cytologically characterized by fluorescent in situ hybridization (FISH). Probes for the 5S and 45S rDNA genes (pTa794 and pTa71, respectively), a highly repetitive rye sequence (pSc119.2), the synthetic oligonucleotide (AAG)5, and total genomic DNA

2. Chromosome characterization in Thinopyrum ponticum (Triticeae, Poaceae) using in situ hybridization with different DNA sequences
Thinopyrum ponticum (2n = 10x = 70, JJJJsJs) belongs to the Triticeae tribe, and is currently used as a source of pathogen resistance genes in wheat breeding. In order to characterize its chromosomes, the number and position of 45S and 5S rDNA sites, as well as the distribution of the repetitive DNA sequences pAs1 and pSc119.2, were identified by fluorescent

3. CaracterizaÃÃo cromossÃmica de hÃbridos intergenÃricos de trigo (Triticum aestivum X Thinopyrum ponticum) com diferentes combinaÃÃes genÃmicas
Foram caracterizados citogeneticamente oito acessos, incluindo a linhagem de trigo PF 839197 (Triticum aestivum, 2n = 42), Thinopyrum ponticum PF Ag. el. 84001 (2n = 70) e seis acessos hÃbridos derivados de PF 839197/PF Ag. el. 84001//2*âCEP19â, com cinco ou sete geraÃÃes de autofecundaÃÃo. Cromossomos de PF 839197 e de Ag. el. 84001 foram analisados
