Associations among alleles at nine nuclear loci and three chloroplast DNA (cpDNA) genotypes were assessed in a sample of 247 accessions of the wild barley, Hordeum vulgare ssp. spontaneum. Alleles at two of the nine nuclear loci are marked by length variations in the intergenic spacer region of ribosomal DNA (rDNA), and those of the other seven loci are well characterized allozymes. The three chloroplast DNA (cpDNA) genotypes are marked by restriction fragment length polymorphisms resulting from three polymorphic restriction sites detected by Southern blot hybridization. The analyses were performed by dividing the nine nuclear loci into a series of two-locus subsets and constructing log-linear models to characterize associations between the subsets of two nuclear loci and the cpDNA genotypes. Statistically significant associations were detected between six of the nine nuclear loci and the cpDNA genotypes, either individually as pairwise correlations, or through interaction with another nuclear locus to form three-variate complexes. Although the sample size of the present study was inadequate for statistical evaluation of higher order interactions, the results suggest the existence of interactions in which more than two nuclear loci are involved in associations with cpDNA genotypes. The observed cytonuclear associations appear to result from interplay among a number of evolutionary forces including a mating system of predominant selfing, differentiation among gene pools of local populations, and adaptation of barley genotypes to specific environmental conditions.
