Abstract

Analysis of the pathogenicity of 800 progeny from a HI-path (Blue) x LO-path (Cream) cross showed that the quantitative genetic control of pathogenicity in Nectria haematococca MPI on hypocotyls of Cucurbita maxima was determined by 6-12 ‘effective factor’ or quantitative trait loci (QTL). In addition there was evidence for a virulence/colony colour gene(s) with an effect that was superimposed on the pathogenicity phenotype.
