Abstract Seed proteins of cultivated lentil (Lens
culinaris ssp. culinaris), its wild relatives--L. culinaris
ssp. orientalis, L. odemensis, L. ervoides, L.
nigricans, and their interspecific hybrids were analysed by sodium dodecyl
sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Protein bands were
scored for presence or absence and genetic distances were calculated and
utilised for split decomposition analysis. Similarity matrix analyses were also
carried out. Results show that L. culinaris ssp. orientalis and
L. odemensis are probably the wild progenitors of cultivated lentil.
Interspecific hybrids show different degrees of genetic similarity to their
parents. Caution is suggested if SDS-PAGE is used to predict genetic
relationships of Lens interspecific hybrids because of differences found
between known genetic similarities, and similarities suggested by SDS-PAGE of
F1 hybrids.
