Influence of parental forms on changes in the content of mineral elements in grain of new winter triticale hybrid strains
Wydanie: 1 / 2010
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 Breedingand 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 inamounts 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 kernelsthan the parental forms. Among all the hybrids, strain IGS 5101 × 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.
