We have developed a nonradioactive oligonucleotide multilocus DNA fingerprinting method for Cynoglossum officinale . Of the 19 probes tested, six probes yielded banding patterns for all restriction enzymes used. All but one of the informative probes are repeats with a four‐base motif. Approximately 60% of the loci appeared to be polymorphic. The sensitivity of the nonradioactive method was equal to that of the radioactive method. In addition, a new simple calculation method is presented to estimate selfing rates and approximate 95% confidence limits from the DNA fingerprint profiles avoiding ‘between‐gel’ comparisons. The selfing rates differed significantly (as determined from 95% confidence intervals) between naturally pollinated individuals of C. officinale within the experimental population. The estimates ranged from 0 to 70% selfing.
