| Abstract/Contents: | The breeding systems of an obligate outbreeder (Plantago lanceolata) and an obligate inbreeder (. patagonica) were compared. Outbreeding in the former and inbreeding in latter species is achieved by self-incompatibility and preanthesis cleistogamy, respectively. The difference in breeding system is accompanied by a difference in the pollen output, pollen to ovule ratio, stigma and anther size, and seed weight. P. ovata, a third species known only in cultivated form, is intermediate. This species has two types of plants, some of which are protogynous and others where stigma receptivity and anther dehiscence synchronize. Although the differences between the two intraspecific variants are not large, they nevertheless suggest that the species is in evolutionary flux. Domestication is known to have modified the breeding system in many crop plants and there is evidence that, in P. ovata, a start in this direction has already been made. |
