| Abstract:
Using interspecific hybridisation techniques, a resistant accession of L. dauricum (section Sinomartagon), was crossed with the susceptible L. longiflorum cultivars 'Gelria' and 'Flevo' (section Leucolirion). The progeny was tested for Fusarium resistance in a standardised scale-bulblet assay. Both resistant and susceptible descendants were found, indicating that the resistance was passed from the resistant parent to the progeny and that the resistance segregates. The level of the most resistant descendants equalled that of the resistant parent. It is concluded that L. dauricum can be used as a source of Fusarium resistance in interspecific crosses with L. longiflorum. | |
