Quantitative studies on the mating system of jute (Corchorus capsularis L.)

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.
