(2020): Do Triticum aestivum L. and Triticum spelta L. Hybrids Constitute a Promising Source Material for Quality Breeding ofNew Wheat Varieties?
AGRONOMY-BASEL. 2020; 10(1), 43 FullText FullText_BOKU

The aim of this two-year study was to determine whether the contents of macronutrients and macro and microelements in wheat grain can be increased by crossbreeding Triticum aestivum and T. spelta. The experimental material comprised the grains of F-6 and F-7 hybrids and their parental forms. The element content of grain was determined by ICP-SFMS. Hybrid grains had significantly higher ash contents than bread wheat grain (1.90% and 1.93% versus 1.62%). Crude protein content was lowest in bread wheat grain (11.75%) and highest in spelt grain (14.67%). Hybrid grains had significantly higher protein contents (12.97% and 13.19 degrees/0) than bread wheat grain. In both years of the study, the concentrations of P, S, Mg and Ca were highest in spelt grain, whereas their content in hybrids was lower than in spelt grain, but higher than in bread wheat grain. The concentrations of desirable microelements were highest in spelt grain, and the micronutrient profile of hybrid grains was more similar to bread wheat than spelt. Therefore, the hybrids can constitute promising source material for quality breeding in wheat.
