The last seven columns give the distribution of the mutation events at each locus, +x (respectively −x) representing a mutation causing the gain (respectively loss) of x repeats. (—) Missing data. (·) No mutation of the corresponding size was observed. Ch, chromosome location in the variety Chinese spring; C.I. 95%, 95% confidence interval.

^aLoci for which the mutation rate has been estimated in a previous study (Thuillet et al. 2002).
