Karyotype Analysis of Triticum boeticum Boise

The karyotype of Triticum boeticun. was investigated. Somatic chromosome number of T. boeticum was found to be 2n=14, and seven pairs of homologous chromosomes were distinguished on the basis of satellites, total length and arm ratio. There are two pairs of chromosomes with satellites, three pairs of relatively long chromosomes and two pairs of comparatively short chromosomes. Three pairs of chromosomes have slightly submedian centromeric position, two pairs of chromosomes have submedian centromeric position, and two pairs of chromosomes have highly submedian centromeric position. The total complement length was found to be 63. 44μm, with an average chromosome length of 9.06μm. The length of the longest chromosome (Chromosome IV) is 10.3lμm, whereas the shortest one (Chromcscme VI) is 7.91μm.
