Sammanfattning

The study describes the genetic structure in sugar beets and in wild beets (Beta vulgaris) using 30 RFLP markers. Samples consisting of pooled plant material of 100 individuals from each line and population were used to analyse 120 sugar beet breeding lines and 91 wild beet populations. Greater variation was found among the wild populations than among the breeding lines. Although the two major groups of breeding lines, monogerm and multigerm, had approximately equal amounts of genetic variation, in the monogerm group more of this variation was partitioned among the lines than within the lines. Furthermore, despite most of the variation being shared by the two groups, the two groups were found to be separated along the first two components in a principal component analysis. Computer simulations were carried out to evaluate the usefulness of the pooled-sample strategy employed in the investigation. These simulations showed the use of pooled samples to be a better alternative than that of analysing a few plants individually.
