Summary

Nearly 35,000 individuals of C. capsularis were scored for selfing versus outcrossing in various populations. Different marker loci, such as anthocyanin pigmentation (C/c), serrated leaf (Sr/sr) and fasciated stem (Fs/fs), were used to determine the male gametes which had effected fertilization. The estimates of the outcrossing parameter, α were found to differ with years, locations and for the marker locus used in the estimation. The outcrossing for C/c was lowest, the outcrossing for Fs/fs was highest and that for Sr/sr was intermediate. The nature of outcrossing, in general, was nonrandom. Selfing predominated in this species.
