In this sense, the present study was carried out to verify the reaction and to estimate genetic parameters of a population of coriander composed of two cultivars (Verdão and HTV Dom Luiz) and 49 half-siblings progenies parasitized by Meloidogyne incognita race 1. The experiment was conducted in a greenhouse in the Department of Agronomy of the Federal Rural University of Pernambuco. The 51 cultivars and progenies were arranged in a randomized block design with four Original Research Article
