Identification of chromosomes involved in translocations in wild Emmer

With the aid of telocentric lines of Emmer wheat, the chromosomes involved in seven chromosome types (one standard type and six translocation types) in wild Emmer, Triticum dicoccoides, were identified. Type Ela was of almost the same chromosome structure as that of durum LD 222 with a small reciprocal translocation between chromosomes 4B and 2B. Type Elb had a major translocation between 2A and 2B and a minor one probably between 2B and 3B. Type E2 had a major translocation between 2B and 3B. Type E3 had a major translocation between 5B and 7B. Type E4 had a major translocation between 4B and 3B and a minor one between 2B and 4B or 3B. Type E5 had a major translocation between 6B and 7B. Type E6 had a major translocation between 1A and 5A. We discussed the result in comparison with the previously reported data on the same translocations.
