Somatic Cell Karyotypes of Three Elytrigia elongata Accessions
Somatic cell karyotypes of three Elytrigia elongata accessions collected from different countries were studied using root tip squash method to provide cytological characteristics and systematic evolution.Results showed that the chromosome karyotype of EE001 collected from Xinjiang of China was K(2n)=10X=70 =50m+ 16sm+ 4st,and the composition of relative length chromosome was 1L+ 17M2 + 15M1 +2S.The chromosome karyotype of EE014 collected from Germany was K (2n) =10X =70 =48m + 20sm +2st,and the composition of relative length chromosome was 3L+ 14M2 + 13M1 +5S.The chromosome karyotype of EE020 collected from Portugal was K(2n) =10X=70 =38m+ 22sm+ 8st + 2t,and the composition of relative length chromosome was 5L + 11M2 + 15M1 + 4S.The chromosome karyotypes of three E.elongata accessions were belonged to "2B" types.
