| Abstract: | Three Dactylis glomerata accessions, which collected from different sites in Yunnan province, were karyotyped. The results showed that all accessions are diploid (2n=2x=14). But the karyotype of the accession collected from Deqin county, which altitude is 3 300 m above sea level, belongs to 2B nuclear type. And the other two accessions collected from Langmu mountain and Zhongdian county, which altitude is about 2 300 m above sea level, belong to 2A nuclear type. |
