Orientale additional and substitutional lines. chromosome number of 96 BC2 F3 individuals were accounted. Fifteen plants with 2n= 43 and eight plants with 2n= 44 were checked out. GISH results of the individuals with 43 chromosomes showed that they blonged to three different monosomic additions. Two disomic additions, ine double-monosomic addition, one trible- monosomic addition and one monosomic addition were found in the 2n = 44 individuals. One double-monosomic substitution and one monosomic sustitution were obtained.
