This study was conducted to determine the influence of wheat cytoplasms on storage protein patterns in wheat and triticale. Euplasmic and alloplasmic triticale had been produced by crossing T. durum and T. aestivum, having nine different cytoplasms, with four rye inbred lines. The gliadin patterns of these euplasmic and alloplasmic primary hexa- and octoploid triticale and the corresponding wheat parents were biochemically analysed, using the acid PAGE as electrophoretic technique. Comparing the gliadin patterns of the euplasmic and alloplasmic wheat parents it was found that the variation of the quantitative expression in the gliadin patterns was amplified in the background of alien wheat cytoplasms. This variation was reduced in alloplasmic triticale, especially in hexaploids. The quantitative expression of rye secalin bands in triticale was influenced by the wheat genome. From this extensive study, it can be concluded that alien wheat cytoplasms produce quantitative and qualitative variations in the expression of gliadin patterns.
