摘要: COROLLA-COLOUR polymorphisms occur in wild populations of many angiosperms, but little is known the selective factors that maintain them. Valentine has suggested yellow/white corolla-colour may be adaptively neutral1. I have observed extremely strong discrimination by some insect pollinators between yellow and white forms polymorphic radish. These observations, which are described below, indicate differences adaptive importance this similar cases.
