| Abstract: | Karyotype was analysed on Psathyrostachys stoloniformis. The resultshowed: The genome of P. stoloniformis consists of 1 submetaceotric chromosomeand 6 metacentric chromosomes. Its karyotype is symmetric and fall into Stebbins'"1A" type. According to the suggestion of Stebbins, evolution tendency of karyotype isfrom symmetry karyotype to unsymmetry one. From this work and the previousreports, the authors compared the karyotype characters of P. fragilis, P. juncea, P.kronenburgii, P. lanuginosa, P. huashanica and P. stoloniformis. Based on the compari-son, the authors considered that P. huashanica is the most advanced one among thespecies discussed in this paper. |
