Cereal Genomics Team conducts research on theoretical and practical aspects of interspecific and intergeneric hybrids as well as substitution, translocation and introgression lines, mainly within wheat (Triticum aestivum L.), rye (Secale cereale L.). and × Triticosecale Witt. The goal of research is to resolve genome organization, to karyotype and to reveal mechanisms of chromosome translocation induction. Furthermore, the aim of work is to extend species biodiversity and to transfer new, valuable genes to improve the quality of yield and resistance to biotic and abiotic stresses.

Research profile

• Analysis of genome organisation of hybrid plants from wide hybridisation between triticale or rye and Aegilops species
• Karyotyping of hybrid plants
• Analysis of genetic mechanisms inducing chromosome translocations
• Extending of triticale genetic variation by intergeneric hybridisation aimed at introducing genes connected with resistance to cereal diseases caused by pathogenic fungi Puccinia triticina and Blumeria graminis
• Searching, collecting and introducing to wheat and triticale traits underlying tolerance to diseases caused by pathogenic fungi from genus Fusarium (Fusarium head blight) and Oculimacula (eyespot)

Research methods

• cytogenetic methods (fluorescence and genomic in situ hybridisation)
• molecular identification of genes of resistance to cereal diseases, caused by pathogenic fungi, with the use of validated molecular and isoenzymatic markers
• in vitro anther cultures
• inoculation tests in field conditions and evaluation of genotypes  (phenotype markers)
• inoculation tests in greenhouse (validation of plant resistance  to pathogenic fungi infection)

Current works

• Analysis of susceptibility to leaf rust(Puccinia triticina) and evaluation of qualitative trait variation  in triticale heksaploid introgressive lines with introduced fragments of Ae. tauschii genome
• Identification of chromosomes in diploid and tetraploid species of wild goatgrasses (Aegilops sp.) and in hybrid forms within tribe Triticeae.
• Searching, creation, evaluation and collecting of resistance sources  to Fusarium head blight in wheat and triticale.
• Analysis of resistance of wheat and triticale genotypes to Fusarium head blight and Fusarium mycotoxin accumulation  in seeds.
• Identification and introduction into the genome of genes determining wheat resistance to eyespot caused by fungi from the genus Oculimacula
