Inheritance and linkage relationships of nine isozyme loci in wild radish

Knowledge of inheritance patterns of genetic markers is important for studies in a variety of fields, but most studies of genetic markers in plants are in managed species or cultivars. We examined inheritance and linkage patterns of nine isozyme loci in a natural population of wild radish (Raphanus raphanistrum), a species that is widely used for ecological and evolutionary research. Little evidence for deviations from Mendelian segregation or strong linkage among loci was found. Therefore, these loci are excellent markers for use in a variety of studies. These results are in agreement with a study of seven of the same loci in R. sativus, except that evidence for linkage between one pair of these loci was reported in the latter species.
