The maize inbred lines 1145 (resistant) and Y331 (susceptible), and the F1, F2 and BC1F1 populations derived from them were inoculated with the pathogen Pythium inflatum Matthews, which causes stalk rot in Zea mays. Field data revealed that the ratio of resistant to susceptible plants was 3:1 in the F2 population, and 1:1 in the BC1F1population, indicating that the resistance to P. inflatum Matthews was controlled by a single dominant gene in the 1145×Y331 cross. The gene that confers… CONTINUE READING
