Abstract

Compatible pollinations from many differenttaxa display nonrandom mating. Here we describe a systemfor examining questions of nonrandom mating in Arabidopsisthaliana. Using this system, we demonstrate thatArabidopsis thaliana displays nonrandom mating betweendistinct accessions. Statistical analysis of these data demonstratesaspects of both pollen competition and male–female complementarity in these matings. Cytologicalexperiments implicate pollen germination and pollen tubegrowth rates as possible causal factors in these nonrandommating efficiencies.
