“…Subsequently, their electrophoretic work further elucidated or confirmed taxonomic relations between species obtained previously by well known classical methods of geographical, morphological, cytological, and hybridization analyses. For example, Fox et al (1964) with Leguminoseae, Vaughan et al (1966) with Brassica, Johnson and Hall (1965), Johnson et al (1967) and Johnson (1967a) with Triticum, Johnson (1967b) with Aegilops, and Desborough and Peloquin (1966, 1969a, 1969b with Solanum, were able to confirm relationships of species as well as of genomes. In the latter seven studies, determination of the ancestry of polyploids of known or unknown origin as well as the possible parental origin for several of the interspecific hybrids were carried out.…”
