Abstract: | Sodium dodecyl sulphate-polyacrylamide gel electrophoresis of reduced seed globulins covered 141 accessions of Lathyrus sativus and the following related species: L. amphicarpos, L. blepharicarpus, L. cicera, L. gorgoni, L. marmoratus, L. pseudocicera and L. stenophyllus. In the total examined material 71 globulin polypeptide bands were distinguished. The number of polypeptide bands detected in particular species varied from 14 in L. amphicarpos to 29 in L. sativus; all the species under study showed intraspecific variation due to individual variation and/or differences among accessions. Electrophoretic data were subjected to statistical analysis using hierarchical UPGMA grouping. Frequency distribution of polypeptide bands in L. sativus showed some correlations with geographical origin and certain seed characteristics (seed coat colour, seed weight) of the studied accessions. As regards interspecific relationships, the studied species showed to be distantly related taxa except for the rather closely allied L. cicera and L. marmoratus. The obtained results are compared with the electrophoretic seed albumin data reported earlier for the same taxa. |
