Research output: Contribution to journalArticlepeer-review


Collections of wild emmer wheat, Triticum dicoccoides, were sampled from 5 sites along an 8 kilometre transect and analysed electrophoretically at seven enzymatic loci and phenotypically at one coleoptile pigment locus. Gametic phase disequilibrium coefficients indicate two major eight locus genotypes and one major recombinant type in the area. The multilocus genotypes are distributed in a step cline with the recombinant genotype being found at the interface between the two genotypes. Analysis of the spatial distribution of genotypes in the one polymorphic population suggests that gene flow by either seed or pollen dispersal must be extremely limited. These observations are briefly discussed in the light of previous reports of high gametic phase disequilibrium in inbreeding plant species.
