Fusarium wilt is the most harmful soil-borne disease of lupins in Russia and in the Ukraine. The aim of the studies was to find broad resistance to disease in collection accessions and to breed lupin forms resistant to Fusarium wilt for the future breeding program. Lupin cultivars and lines (547 accessions) from the genebank of the N.I. Vavilov All Russian Scientific Research Institute of Plant Industry, St. Petersburg, Russia, were tested for Fusarium resistance under different environmental conditions of three regions in Russia and in the Ukraine on plots with artificially infested soil. So, differences in the disease susceptibility of the same accessions were found in contrasting environments. Resistant forms from one region were crossed with accessions showing their resistance in two other regions to accumulate resistance genes in new genotypes. As a result of hybridization two transgressive forms were obtained in F₄ of the crosses cv. Frost × cv. Apendrilon (L. angustifolius) and line G-413 × line 85 (L. luleus). Their resistance in all three regions appeared to be higher than that of their parental forms. These two lines were found suitable for the breeding programme of Fusarium resistant forms in Russia and in the Ukraine.
