Relative fitness of selfed and outcrossed progeny in a self- compatible, protandrous species, Sabatia angularis L. (Gentianaceae) : a comparison in three environments

Abstract

Significant inbreeding depression was detected between the self and far-outcross progeny in each environment. Only the natural environment demonstrated a >50% reduction in relative fitness of self compared to near-outcross progeny. The magnitude of the inbreeding depression expressed among the self progeny was the greatest in the field, intermediate in the garden plot, and the least in the greenhouse. -from Author
