Cytological evalution of Miscanthus sinensis in China

Miscanthus is one of the most important plant genus for fiber biomass development which has drawn the keen attentions throughout the world.China is one of the origins of Miscanthus with wide and abundant distribution and highly genetic diversity.Studies of Miscanthus germplasm will facilitate development of bioenergy industry in China.The ploidy in total of 30 accessions of M.sinensis collected from ten provinces of China was identified using optical microscope and flow cytometry.The results showed that all thirty accessions were diploidy with a cytotype of 2n=2x=38,suggesting that diploid may be the major cytotype for wild Miscanthus sinensis in China.
