Abstract

Australia is host to five species of rice (Oryza sp.) which is about one fifth of the species in the genus. Most rices species are wild, sometimes weedy, and are found largely in tropical to subtropical climates.Wild rice plants usually grow to 1.0-1.5 m tall, however, we have one accession that is well in excess of 2.0 m. As this characteristic is heritable it is tempting to compare the heights in wild rice with the known genes for height in wheat and sorghum.Oryza meridionalis and O. australiensis are prime candidates for domestication. Both species produce grain that can be polished to ‘brown’ and ‘white’ rice as well as milled to a fine white flour. Our research has found that this flour has cooking qualities that are within the range of cultivated rice found on supermarket shelves.We believe that once the problem of seed shedding has been overcome and proves to be a character that is easily heritable, domestication, to the point of evaluating specific genotypes, could be achieved.
