Field, Greenhouse and Detached-Leaf Evaluation of Tomato (Lycopersicon esculentum Mill.) Genotypes for Late Blight Resistance

摘要

Twenty one tomato (Lycopersicon esculentum Mill.) genotypes were evaluated during September 2011 to August 2012 to estimate the level of their resistance to late blight infection so as to identify better resistant varieties. The experiment was conducted at Mizan-Tepi University trial field using Randomized Complete Block Design (RCBD) with three replications. The genotypes CLN-2037I, Roma VF, CLN-2037H, Melkashola, CLN-2037H and CLN-2037E, showed relatively better resistance to late blight infectionunder field condition, green house and detached-leaf evaluation, revealing their better resistance performance to late blight infection. So that, these genotypes could be selected as resistant varieties to late blight and also could be considered in hybridization program as a source of resistant gene to late blight in developing resistant varieties.
