ISOENZYMATIC CHARACTERIZATION OF SOME LATHYRUS L AND VICIA L SPECIES (LEGUMINOSAE) OCCURRING IN RIO-GRANDE-DO-SUL (SOUTHERN BRAZIL)

MDH, ME and SOD electrophoretic patterns were studied in 18 accessions of five Lathyrus and 18 accessions of nine Vicia species, using polya crylamide gels, Scandalios (Biochem. Genet. 3: 37-79, 1969) buffer sys tems and specific staining solutions for each enzyme. For both genera, more than one pattern for each system for each species was found, wit h few exceptions. Phenograms constructed using Jaccard's similarity co efficients and the simple linkage grouping method showed that, in gene ral, species relationships determined by isoenzymes are in accordance with taxonomic classification.
