Summary
The results of intercrossing 11 fertile F1 individuals obtained from an interspecific cross between two self-incompatible species of Gasteria, viz. G. liliputana and G. humilis, reveal that at least two genes control the self-incompatibility reaction. The site of pollen tube inhibition in incompatible matings is confirmed as the ovule.
