Abstract

Electrophoretic analysis of seed albumins covered 105 Lathyrus sativus accessions originating from different geographical regions. Four major albumin bands were responsible for the detected variation. Due to differences in the number and combination of these bands, eleven electrophoretic seed albumin patterns were distinguished; four of them were rare phenotypes found in less than 1% of the 817 examined individuals. Electrophoretic data were subjected to statistical analysis using hierarchical UPGMA grouping and biplot techniques. Generally, no correlation was found between occurrence of either the seed albumin patterns or the major albumin bands and geographical origin of the forms under study. On the other hand, data concerning frequency distribution of the major albumin bands tended to separate two groups of accessions, white-seeded with large seeds and coloured-seeded with relatively small seeds; coloured-seeded accessions with rather large seeds mixed with the above groups.
