Abstract:

The Karyotyp of the primary wheat-whastgrass alien addition line TAI-27 was 2n = 44 in which all d the chromosomes were metacentric and subrmetacentric. However, in the progeny of TAI-27 a pair of chromosomes had become small chromosomea in the two morphologically different plants. Fluorescence in situ hybridizstionm (FISH) technique was used to analyze the two different plants. The observations indicate that a pair of small chromosomes in one varietion line are from wheatgrass. In another variation line, a pair of small chromosomes are also from whest-grass, while another pair of wheatgrass chromosomes have substituted the wheat chromosomes. TAI-27 and its variant lines showed a high level of resistance to barley yellow dwarf virus (BYDV). The pessible explanation for such a variation and the potential use of the variant lines were discussed briefly.
