| Abstract:
Fungal diseases: Powdery mildew (Sphaerotheca mors-uvae), Septoria leaf spot (Mycosphaerella ribis) and Anthracnose (Pseudopeziza ribis) are among the major problems for black currant growers. Interspecific hybridisation is one of the most effective methods to solve this problem by creating resistant cultivars. Hybrids of Ribes nigrum x R. uva-crispa, R. nigrum x R. petraeum, R. nigrum x R. aureum, R. nigrum x R. americanum, R. nigrum x R. sanguineum were obtained after performing currant interspecific hybridisation and growing isolated embryos in vitro. The PCR technique was used for identification of the plants hybrid nature. Fertile plants were obtained in all crosses. Hybrids in the F1 generation of R. nigrum x R. americanum and R. nigrum x R. sanguineum were resistant to powdery mildew. The average damage reached 0.25 and 0.35 respectively (based on 0-5 scale). In crosses of R. nigrum x R. uva-crispa and R. nigrum x R. petraeum there were 29.5% and 25.0% of undamaged plants selected respectively. All hybrids in the F1 generation of R. nigrum ‘Ben Tirran’ x R. sanguineum ‘Rs-01’ were undamaged by Septoria leaf spot. | |
