| Summary: | Wheat maternal male-sterile forms and paternal ones possesing a fertilityrestoring ability were used for obtaining series of F1 hybrids and in this material total N, protein fractional composition and total extractability, as well as the compactness of molecules contained in the particular fractions, were determined. It was found, that the above mentioned properties in the F1 generation were influenced to a significant extent by the maternal forms. Particularly important for wheat breeding in the direction of improving the baking quality is the influence of maternal forms on the content of proteins soluble in NaOH, which contain high molecular weight glutenin, as well as on the compactness of the malecules contained in it. The data presented In this paper indicate, that selection of maternal forms for crosses should be performed with great care.
