Avaliação de genótipos de Capsicum para resistência ao ácaro branco
[Evaluation of Capsicum genotypes for resistance to the broad mite]
Horticultura Brasileira 20 (2), 217-221
Abstract: Fifteen Capsicum accessions from the Vegetable Crops Germplasm Bank from the Universidade Federal de Viçosa (Brazil), one hybrid and four pepper cultivars were evaluated in greenhouse for resistance to the broad mite (Polyphagotarsonemus latus). The experiment was set in a completely randomized (split plot in time) design with six replicates per genotype. Evaluations were performed either by counting the number of adult mites present on leaf samples weekly collected or by a grading scale related to symptom severity on infested plants. Symptoms assessment was shown to be more suitable for separating genotypes in resistant or susceptible to the mite. The accessions BGH/UFV 1774 (C. annuum) and BGH/UFV 5086 (C. frutescens) were respectively ranked as resistant and highly resistant to P. latus under severe testing conditions.
