European maize landraces are valuable resources for plant breeding. The ability to generate double haploids (DH) in a single step allows valuable traits to be transferred directly from landraces to elite breeding material. In a previous project, five to eight DH lines each with superior resistance to cob fusariosis were selected from two old landraces, 'Petkuser Ferdinand Rot' from Petkus/Brandenburg and 'Kemater Landmais Gelb' from Tyrol/Austria. These were used, together with two susceptible lines each as controls, to produce various cross and backcross progeny with three elite flint lines. These will be characterised by phenotypic analysis in four environments. The aim is to correlate resistance to the three major cob rot pathogens Fusarium graminearum, F. verticillioides and F. temperatum by artificial inoculation. DH lines will be derived from the best progeny and will be phenotyped and genotyped. Quantitative and association genetic analyses will be performed on the data. | |
