Quantitative genetic variability for six characters was estimated in four populations of the annual plant, Collinsia heterophylla, with estimated selfing rates ranging from 0.36 to 0.68. Based on large samples of parental plants, all four populations showed significant genetic variation for two or more characters, and there was no sign that the more selfing populations had lower amounts of genetic variance or lower heritability values. Autogamous fruit set rates in the absence of pollinators also showed significant heritability in one population. Reprinted by permission of the publisher.
