“…It is significant that the corky complementary alleles are most common in areas where the two species overlap. On the other hand, genetic divergence can sometimes originate, by chance, a tendency towards reproductive isolation as shown for instance by Santibaiiez and Waddington (1958) and Rick (1963).…”

“…However, some evidence has suggested that, at least for pre-zygotic isolation, asymmetries may be common, having been reported in Drosophila (Kaneshiro 1980), salamanders , leaf beetles (Funk 1998) and several plant species (e.g. Grant 1954;Lewis & Crowe 1958;Rick 1963;Kiang & Hamrick 1978;Prentice 1978). If asymmetries between lineages occur commonly, then reproductive isolation may be caused by mechanisms other than ¢xa-tion of incompatible nuclear alleles or chromosomal rearrangements.…”

Patterns of reproductive isolation between species may provide insight into the mechanisms and evolution of barriers to interspeci¢c gene exchange. We used data from published interspeci¢c hybridization experiments from 14 genera of angiosperms in order to test for the presence of asymmetrical barriers to gene exchange. Reproductive isolation was examined at three life-history stages: the ability of interspeci¢c crosses to produce seeds, the viability of F 1 hybrids, and the fertility of F 1 hybrids. Statistically signi¢cant asymmetries in the strength of reproductive isolation between species were detected in all genera and at each of the three life-history stages. Asymmetries in seed production may be caused by a variety of mechanisms including di¡erences in stigma/style lengths, self compatibility and di¡erential fruit abortion. Asymmetries in post-zygotic isolation are probably caused by nuclear^cytoplasmic interactions. Asymmetrical reproductive isolation between plant taxa may have important implications for the dynamics of hybrid zones, the direction of genetic introgression and the probability of reinforcement.

The plant group dealt with in this paper comprises two cultivated species, Oryza sativa L, and 0. glaberrima Steud. and their respective wild relatives, 0. perennis Moench and 0. breviligulata Chev. et Roehr. On circumstantial evidence, sativa must have arisen from the Asian form of perennis (Oka and Chang 1962;Oka 1964a), and glaberrima from breviligulata independently of sativa (Morishima et al. 1963). 0. glaberrima and 0. breviligulata (Series Glaberrima) are endemic to West Africa, while 0. sativa and 0.
