Authors made approach to genetic variability and genetic structure of 30 clonal populations of Arundinella hirta in northeastern Song Nen steppe in China using enzyme electrophoresis and isozome analysis. Our study obtained the following results: means of P, A, AP, Ho and He in 30 populations were 17.00%, 1.17, 2.03, 0.103 and 0.063, respectively at the population level. The population with highest allelic diversity possessed 38.71% of the total allelic diversity in our sample. All of the alleles encountere...
