Attempts were made to produce tetraploid triticales by crossing 6x triticales with diploid rye. In F2, the chromosome number was reduced to between 15 and 23 except in three plants, where the chromosome number was 28, 32 and 38, respectively. An increased frequency of ring bivalents was observed in many F4 plants. In the progeny of the plant with 28 chromosomes, desired plants (four) with 2n = 28 chromosomes were obtained. Data on various agronomic characters were recorded on the progeny of these plants in F5. Reasonably good fertility was noticed in these tetraploid triticale forms.
