Karyotype of aegilops squarrosa L.

Aegilops squarrosa L.의 核型分析

The conventional karyotype and the C-banding pattern of Aegilops squarrosa were investigated, and the results are as follows; Seven pairs of homologous chromosomes of Ae. squarrosa were well distinguished on the basis of satellite, total length and arm ratio. There were one pair of sat-chromosome, three pairs of relatively long chromosomes and three pairs of relatively short chromosomes. Two pairs of chromosomes have median centromeric position. The total complement length was found to be 50.27 ㎛, with an average chromosome length 7.18 ㎛. According to the C-banding pattern of Ae. squarrosa, it is obvious that Ae. squarrosa possesses enough intercalary bands.
