“…Various resistant cultivars have been produced (Barksdale et al, 1984;Bosland, 2010;Guerrero-Moreno and Laborde, 1980;Kimble and Grogan, 1960;Pochard and Chambonnet, 1971), but these cultivars are not resistant at all locations (Oelke et al, 2003). Previous studies have determined factors that affect the expression of resistance genotypes; e.g., plant age, P. capsici isolate origin, zoospore concentration, and inoculation method (Ortega and Espanol, 1983;Pochard and Chambonnet, 1971;Pochard et al, 1976;Reifschneider et al, 1986a).…”
