 ABSTRACT

In this study, two effective screening methods were used to compare 11 Mediterranean olive varieties for their tolerance to Verticillium dahliae Kleb. (i) inoculation method using butanolic extract of Verticillium dahliae Kleb liquid culture (ii) A natural phytotoxin as a new rapid selection tool. The purpose of these in-vitro tests was to compare their effectiveness and their capacity to differentiate levels of tolerance /susceptibility to Verticillium wilt in Olive varieties. Result indicate that the two screening method have the same sensitivity in identifying variable levels of olive tolerance to Verticillium wilt. Both methods confirmed that Bel Elanza is highly tolerant cultivar. Hence, using natural phytotoxin was less costly and requires less time and space than the standard inoculation and evaluation methods like pot immersion, bare-root dipping or stem injection using a conidial suspension of a defoliating pathotype of Verticillium dahliae isolate.
