Abstract	Hitherto studies univocally point out the possibility of gene transfer from Agrotriticum hybrids and its utilization for triticale improvement. The aim of the study was to analyse the level of some yield elements of a hybrid between triticale ( Triticosecale ) and Agrotriticum sp. compared to standard triticale varieties in breeding experiments. It would allow the evaluation of the usefulness of the studied material in triticale breeding. The introgressed hexaploid winter triticale strain LAD 965/98 and three standard winter triticale varieties (Bogo, Lamberto and Woltario) were the main objects for the study. The studied strain was derived from crossbreeding of winter hexaploid triticale CZR 1132/90 ((Liwilla x Donar) x Liwilla) with Agrotriticum PPG 113, from VIR in Sankt Petersburg, Russia, and followed by two backcrosses to CZR 1132/90 triticale. The hybrid plants were reproduced by self-pollination and subjected to selection for important quantitative and qualitative traits. The studied forms were introduced in breeding experiments in Poland and were tested in three vegetation seasons 1999-2000 (B SUB 2 /F SUB 6 ), 2000-01 (B SUB 2 /F SUB 7 ), 2001/02 (B SUB 2 /F SUB 8 ), at several sites. The numbers of objects in the successive years' experiments were 49, 41 and 41, respectively. The last experiment ranked as the preliminary state trial. The strain LAD 965/98 appeared to be valuable from the breeder's point of view, because it gave high yields (from 79.5 to 89.9 dt/ha) and was ranked at the first place (106.7% of the standard), seventh (108.1% of the standard) and eleventh (105.0% of the standard), in respective years. Furthermore, compared to mean values for the standards, it was distinguished by the highest 1000-kernel weight, lowest grain sprouting and lowest infection by some pathogens causing leaf and spike diseases. Great breeding value of the triticale can result from the transfer of favourable genes originating from Agrotriticum sp. or cooperation of genes forming its genotype, which is confirmed by the usefulness of achieving the reciprocal hybrids
