FIELD EVALUATION OF SOME STRAWBERRY CULTIVARS REGARDING THEIR BEHAVIOR TO FUNGAL PATHOGENS

Abstract

The researches were done between 2012-2013, many observation and assessments being carried out in strawberry field, on the incidence (F%), severity (I notes; I %) and damages degree (DD%) of diseases which affect the strawberries foliage: Mycosphaerela fragariae - leaf spot, Podosphaera aphanis - powdery mildew and Diplocarpon earliana - leaf scorch. Under the environment of South-central of Roumania, the most tolerant cvs. on the Mycosphaerela fragariae - leaf spot were: ‘Cambridge Favourite’ (GA%=0.00-0.06) and ‘Mira’ (GA%=0.00-0.86). As regard the behavior on the Podosphaera aphanis - powdery mildew attack, the most tolerant cvs. were ‘Cambridge Favourite’, ‘Onebor’, ‘Idea’ (GA%=0.00) and ‘Elsanta’ (GA%=0.00-1.70). The most tolerant cvs. on the Mycosphaerela fragariae - leaf spot were: ‘Benton’, ‘Mira’, ‘Idea’ (GA%=0.00) and ‘Cambridge Favourite’ (GA%=0.00-0.03). ‘Mira’ and ‘Onebor’ are still used in strawberry breeding
