Cultivated lentil L. culinaris was crossed to the wild species L. tomentosus ILWL90 and ILWL120. An ovule rescue technique was used to overcome interspecific incompatibility. Out of 296 hybrid ovules being planted in vitro 27 explants began to grow and three hybrids were recovered. A hybrid between L. culinaris and L. tomentosus accession ILWL90 was obtained by means of ovule recovery only. F1 plant and next generations of the hybrid were either sterile or partly fertile. Hybridization with L. tomentosus accession ILWL120 was achieved by ovule culture as well as in a usual way i.e. without ovule culture. Seed progenies of these hybrids were fertile in both cases. Breeding lines recombinant in flower, seed coat and cotyledon coloring were developed as a result of multiple regular selection for highly productive plants in F2–F7 (L. culinaris × L. tomentosus ILWL120).
