The paper presents a study on the content of Ca, Mg, K, Mn, Zn, Cu, and Fe in kernels (F5 generation) of winter triticale produced by crossbreeding three maternal with two paternal forms. As maternal forms, two strains were used, IGS 5101, FDT 975, as well as cultivar Alzo. The paternal components consisted of strains LAD 122 and F 8063. Morphologically established hybrid strains were selected at the Institute of Genetics, Plant Breeding and Biotechnology of the University of Life Sciences in Lublin. The component selection for crossbreeding was performed to achieve hybrids with great yield-forming potential and to improve the resistance to grain sprouting. Minerals were determined by the atomic absorption spectrometry (AAS) method. The results revealed differentiation in amounts of the analysed mineral components in hybrids depending on genotypes of the parental forms. Hybrid strains were usually characterized by a lower ash content in kernels than the parental forms. Among all the hybrids, strain IGS 5101 x F 8063 was distinguishable by its higher content of K, Ca, Mn, and Fe in grain versus both parental forms. It also excelled exceeded the other hybrids in respect of Ca, K and Mn. Tests on the mineral components in hybrid triticale strains indicate that it is possible to shape their levels through an appropriate selection of parental forms and selection during breeding work on X Triticosecale Wittmack genus to achieve cultivars of improved nutritional value.

The HMW glutenin subunits (SDS-PAGE) and gliadin subunits (A-PAGE) were analysed in selected triticale hybrids and their parental forms. In order to enable further selection of new high-quality hybrid strains of winter triticale determinations were also carried out for protein content, falling number and soluble pentosans level. Among the identified glutenin subunits coded by loci Glu A1 both in the parental forms and in hybrids the qualitatively advantageous subunit 2* usually occurred. Glutenin subunits coded by Glu-B1: 7+25, 7+8, 6+8 for hybrids strains: IGS 5101 x LAD 122, FDT 975 x LAD 122 and Alzo x F 8063 were consistent with maternal forms. In the Alzo x F 8063 strains the additional subunits not detected in parental forms were identified as well. Electrophoretic analysis of gliadin proteins showed intralinear polymorphism of these proteins. The studies pointed to parental genotypes as the most valuable ones because of the quality of grain of hybrids: the maternal FDT 975 and paternal LAD 122. The hybrid strain FDT 975 x LAD 122 was characterised by presence of qualitatively good glutenin subunits, the highest falling number, and a higher content of soluble pentosans in the grain.
