The population genetics of the selfincompatibility polymorphism in papaver rhoeas. X. An association between incompatibility genotype and seed dormancy

Abstract

Further analysis of data presented in a previous paper (Lane & Lawrence, 1995) has revealed an association between incompatibility genotype and seed dormancy such that the seed of crosses in which the wild-type allele, S10, was segregating was a little less dormant, and those in which S11 was segregating was slightly more dormant, than the average for the families in which these crosses occurred. It is argued that this association is caused by the linkage of the 5-locus to one or more genes that determine seed dormancy in this species and that this linkage is one possible cause of the unequal 5-allele frequencies observed in the natural population from which the wild-type parents of these progenies were obtained. © 1995 The Genetical Society of Great Britain.
