The results showed that karyotypic type of Ya01-21was 2n=104＝100m+4sm（4SAT）, Chromosome length ratio of the longest and the shortest 4.25, the average arm-ratio 1.35, belonging to 2C type of chromosome. Molecule identified combine with chromosome studied indicated that Ya01-21 was a progenies of Erianthus arundinaceum. following the law of n+n; ITS identify showed that Ya01-21 is a progenies of Erianthus arundinaceum, the somatic chromosome karyotypic type of Ya01-36 was 2n=132＝130m+2sm, Chromosome length ratio of the longest and the shortest 3.94, the average arm-ratio 1.27, belonging to 2B type of chromosome, combining the advance of characters the law of 2n+n can be resumed.

研究结果表明，崖城01－21的体细胞染色体核型公式为2n＝104＝100m+4sm（4SAT），最长与最短染色体的长度比为4.25，平均臂比1.35，染色体属2C型，分子鉴定结合细胞学研究认为其为斑茅的真实后代，其染色体遗传为n+n；崖城01－36经ITS签定为真实杂种，其体细胞染色体核型公式为2n＝132＝130m+2sm，最长与最短染色体的长度比为3.94，平均臂比1.27，染色体属2B型，结合其性状的进展，推断亲本向其传递染色体可能以2n+n的方式进行。

A fungus CTB430-1 with resistance to copper and zinc was isolated from soil at a copper and Zinc Tailing of Linxiang in Yueyang city, Hunan province. The fungus was identified by analyzing the morphology and measuring the ITS sequence. The effects of pH, initial concentration, co-ions on the growth of CTB430-1 and bioaccumulation of Cu2+ and Zn2+ were studied. The protein and glutathione in the cells were determined by using the coomassie brilliant blue method and iodometric method, respectively.
