Abstract

A series of crossing combinations was made using ten winter wheat varieties, the frost resistance values of which differed significantly from each other in freezing tests carried out in the phytotron at -15 °C. The frost resistance of the varieties and of the F1 generations of the twelve combinations created was determined at various freezing temperatures (-12, -14, -16 and -18 °C) under phytotronic conditions. The dominance of frost resistance changed as a function of the freezing temperature. At a relatively mild freezing temperature (-12 °C) frost resistance was dominant, but as the testing temperature decreased the direction of dominance was reversed and at lower freezing temperatures (-16 and -18 °C) frost sensitivity became dominant. This change in the direction of dominance occurred at a different freezing temperature for each cross. When one of the parents was weakly resistant and the other moderately resistant to frost (e.g. GK Szeged x Bankuti 1201) the direction of dominance was reversed between -12 °C and -14 °C; where one parent had good frost resistance and the other moderate (e.g. Disponent x Rivoli) this change occurred between -14 °C and -16 °C, while in crosses between varieties with excellent and moderate frost resistance (e.g. Martonvasari 4 x Martonvasari 10) the reversal of dominance took place between -16 and -18 °C.
