Abstract

A study was conducted in Puerto Rico to estimate the outcrossing rate of six common bean (Phaseolus vulgaris L.) genotypes when planted in December or May. Two experiments were conducted for each date, one using indeterminate and the other determinate genotypes. In each experiment, homozygous dominant and recessive genotypes were planted in alternate rows to permit natural cross-pollination. Percent outcrossing was calculated based on the number of heterozygous individuals observed in the progeny of the homozygous recessive rows. Significant differences in the rate of outcrossing were observed between genotypes and between planting dates. The dwarf outcrossing (do) genotype had rates of 15.9% and 39.3% for the December and May planting dates, respectively. Outcrossing rates of stipelless lanceolate leaf (sl) and dark green savoy (dgs) genotypes did not differ significantly from the white-flowered (p) genotype, which was < 1% for both dates. Outcrossing rates < 1% were also observed for both planting dates for the determinate genotypes.
