Intraspecific chromosomal polymorphism of Triticum araraticum (Poaceae) detected by C-banding technique

Different Triticum araraticum lines were studied by C-banding method. The intraspecific divergence of T. araraticum was shown to be caused mainly by large chromosomal rearrangements. Two main chromosomal types were distinguished among the studied lines: (1) a karyotype similar to that of T. timophee...

Description
Summary:Different Triticum araraticum lines were studied by C-banding method. The intraspecific divergence of T. araraticum was shown to be caused mainly by large chromosomal rearrangements. Two main chromosomal types were distinguished among the studied lines: (1) a karyotype similar to that of T. timopheevii and (2) different one. The first type includes some lines of T. araraticum subspp. kurdistanicum and araraticum; the second comprises most lines of T. araraticum subsp. araraticum. The lines of the first type can give fertile F1 hybrids with T. timopheevii.
