An evaluation of resynthesized (RS) Brassica napus (AACC) lines derived from two crosses, T19 × ECD11 and T19 × JL04, and semi-resynthesized (SRS) lines derived from DH16516 (DHT) × (T19 × ECD11) was conducted for clubroot resistance against 8 strains of Plasmodiophora brassicae. The root phenotypes of resynthesized lines, semi-resynthesized lines, parental lines (T19, ECD11, JL04) and susceptible (S) control lines DH16516 and NRC11-24 (N1) after six weeks of inoculation with strain SK29.
