Table 1 Responses of parents and progenies of experimental crosses of pepper lines ‘PBC932’ and ‘77013’ to infection by Colletotrichum acutatum at 7 days after inoculation. Separation ratios of disease-resistant and disease-susceptible plants in BC4S1, BC4S2–1, and BC4S2–2 populations fitted significantly with 9:7 or 1:3 Mendelian models
