Abstract
La investigación se realizó en el 2006 en la Granja Experimental “Yuyucocha” de
la Universidad Técnica del Norte en la Parroquia Caranqui, Cantón Ibarra,
Provincia de Imbabura y en el laboratorio de Hematología del Departamento de
Protección Vegetal del Instituto Nacional de Investigaciones Agropecuarias
(INIAP) Quito-Ecuador.
Veinte materiales comerciales de tomate de mesa cultivadas en invernadero se
evaluaron al parasitismo de Meloidogyne incógnita, para verificar su resistencia o
tolerancia y veinte y seis materiales para determinar su comportamiento al
parasitismo de Nacobbus aberrans. A cuatro plántulas (variedades e híbridos de
tomate de mesa) de cada material crecidas en macetas, se inocularon con 70000
huevos y larvas J2 de cada nematodo y a cuatro no se inocularon.
The research was carried in the Experimental Farni "Yuyucocha" of the Universidad Técnica del Norte in Caranqui, town Ibarra, province of Imbabura and in the Nematología at Plant Protection Department Agricultura National Institute (INIAP) in 2006. Twenty commercial materials of tomato grown under greenhouse the parasitism for .Meloidogyne incógnita, to verify their resistance or tolerance and twenty six materials to determine their response to the parasitism of Nacobbus aberrans , four plants were evaluated by each one of the (varieties and hybrid of tomato) material grown in gayéis, they were inoculated with 70000 eggs and larvas J2 of each nematode and four were not inoculated.
