Abstract

We used AFLP (amplified fragment length polymorphism) markers to analyse changes in population genetic differentiation (‘genetic shift’) over time in red and white clover germplasm, and to assess the effect of contrasting sites (Iceland, Sweden and the UK) on the magnitude of these changes. The AFLP technique successfully identified populations in which genetic shift had occurred. The clearest evidence of this was in Sweden within the short time span of three years. This site showed the greatest annual amplitude in temperature duringthe experiment and was also the driest, and one or both of these factors may have exerted strong directional selective pressure on the populations grown there.
