Genetic control of self-incompatibility in Anagallis monelli (Primulaceae: Myrsinaceae).
The genetic control of self-incompatibility (SI) was studied in the Mediterranean short-lived perennial species Anagallis monelli (Primulaceae: Myrsinaceae). Arrays of siblings, including families derived from reciprocal crosses, were cross-pollinated in full diallels, and compatibility groups were assesssed from a census of fruit-set. Two, three and four intercompatible and intraincompatible groups were found. These crossing relationships fit the model for gametophytic SI controlled by a single polymorphic gene locus in families derived from parents with one or no S alleles in common (two vs. four compatibility groups), whilst one genotype was presumed to be missing in the small families that showed only three compatibility groups.
