IDENTIFICATION OF CHROMOSOMES INVOLVED IN TRANSLOCATIONS IN WILD EMMER

With the aid of telocentric lines of Emmer wheat, the chromosomes invo lved in seven chromosome types (one standard type and six translocatio n types) in wild Emmer, Triticum dicoccoides, were identified. Type El a was of almost the same chromosome structure as that of durum LD 222 with a small reciprocal translocation between chromosomes 4B and 2B. T ype E1b had a major translocation between 2A and 2B and a minor one pr obably 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. Ty pe E6 had a major translocation between 1A and 5A. We discussed the re sult in comparison with the previously reported data on the same trans locations.
