PRODUCTION AND CYTOGENETIC ANALYSIS OF THE F1-HYBRID, ELYMUS-CANINUS TRITICUM-AESTIVUM AND THE BACKCROSS TO TRITICUM-AESTIVUM

Elymus caninus (L.) L, 2n = 4x = 28, SSHH was crossed with Triticum aestivum (L.) Thell, 2n = 6x = AABBDD. The seed set was ca 1%. The surviving hybrids had a low seedset when backcrossed to wheat. The chromosome pairing in the F1 hybrid was very low with 0.06-0.14 chiasmata/cell. Also the BC1 had low pairing with 29.83 chiasmata/cell, 11.83 rings and 5.58 rod bivalents.
