Possibility of utilization of two Aegilops sp. to enhance nutritive value of triticale

Abstrakt

Study was undertaken to determine the possibility of improving the nutritive value of triticale by crossing it with two species of Aegilops . Materials for this study comprised of 5 triticale recombinants with Aegilops crassa Boiss 4x and Aegilops juvenalis (Thell) and 4 parental triticale forms. Parental species of Aegilops were not analysed because of difficulties in obtaining the needed quantity and quality of the grains. As compared to parental triticale forms the recombinants of triticale with Aegilops sp. characterized with a greater thousand kernel weight and volume weight, higher content of protein and dietary fibre, especially of its soluble non-starch polysaccharides fraction. Aegilops sp. had not a negative effect on digestibility of protein. The higher content of protein in triticale recombinants resulted however, in poorer values of protein quality indicators, such as lysine content, chemical score, essential amino acid index, biological value and net protein utilization. The other qualitative traits in hybrids did not differ from that received for parental forms. This preliminary study has shown that Aegilops crassa might be utilized for the improvement of triticale grain designated rather for food production, while Aegilops juvenalis for feeding purposes. Selection of appropriate triticale forms it seems also very important in this respect.
