Location of the self-incompatibility locus in an RFLP and RAPD map of Brassica oleracea.
A single locus controlling self-incompatibility (SI) was located on an RFLP and RAPD linkage map of Brassica oleracea by assaying for SI phenotype and segregation of an RFLP locus detected by the cloned St gene SLG6. The map was developed using an F2 population derived from a cabbage x broccoli cross and included 112 RFLP and 47 RAPD loci arranged into nine main linkage groups covering 921 cM. A portion of the population was assayed for St reaction by pollinating with the broccoli parent. The SI reactions cosegregated precisely with the RFLP locus detected by SLG6, and this locus mapped to linkage group 2.
