Late blight symptoms severity on chosen tomato cultigens under natural P. infestans field infections.

aData were collected from 2009 to 2013 in two locations (Skierniewice, Boguchwała).bThe disease assessment scale is based on the % area of leaf and stem infection (1 = 100% percent area infected; 9 = lack of symptoms or few small necrotic spots). Disease symptoms were scored yearly, when LB susceptible control ‘Rumba’ reached maximal intensity of LB symptoms. Data presented is the mean ± SD from DSI recorded on leaves and stems. LSD0.05 calculated according to Tukey procedure for comparing cultigens in each year and in either location: 0.76, and for comparing cultigens in each year and between locations: 0.55.Late blight symptoms severity on chosen tomato cultigens under natural P. infestans field infections.
