Morphological and isozyme markers are useful supplements to molecular marker maps and can be used in comparative mapping studies. Isozymes, as neutral markers, have been used to study genic and evolutionary relationships among related species. In this study, the genetics of six morphological traits and isozyme variants of four enzyme systems were investigated with F2/F2:3 populations derived from three crosses of three As-genome diploid oat (Avena spp.) accessions. All traits and variants conformed to a model of monogenic inheritance except for lemma color. The four enzyme systems yielded six putative variant isozyme loci. Phenotypic data of the five monogenically inherited morphological traits and six isozyme loci were subjected to a pair-wise linkage analysis. Five linked pairs of loci were found. Multipoint linkage analysis identified a loose linkage group of two morphological and two isozyme loci. Included in the linkage group was a locus conferring alkaline ß-galactosidase (Bg/1) and an esterase (Ests) locus. A similar linkage has been observed in hexaploid oat and barley. Additional studies are planned to verify and assign the small linkage group and to assign the remaining unlinked markers. This new information will facilitate further mapping comparisons and evolution studies with Avena.
