Abstrakt

Qualitative characteristics (kernel and volume weights, the contents of protein, lysine and pentosan, extract viscosity and falling number) of inbred lines created in hybrid breeding program of rye was evaluated in two consecutive years, 1998 (no 135) and 1999 (no 78). Two groups of rye inbred lines were selected, which present opposite physicochemical properties and thus fulfilling requirements either for bread making or animal feeding. Some lines might be directly utilised as components of experimental hybrids or as donors of qualitative traits for the development of the second cycle inbred lines.
