| Abstract | The level of polymorphism, genetic variability and relatedness of a population of Poa annua L. from South Shetlands Islands was studied and compared with results obtained for populations from two potential sources of introduction (Argentina-Ushuaia and Poland-Dziekanow Lesny) using the amplified fragment length polymorphism (AFLP) approach. Five primer pairs used for AFLP profiling amplified 226 scoreable DNA fragments that were used for Clustral and Factorial analyses. The level of molecular variability among all individuals from all the analysed populations reaches 30%. Clustral and Factorial analyses show that all populations formed clear-cut uniform groups according to their locations. (mod. journ. abst.) |
