<p>Mediante los descriptores de IBPGR se caracterizaron y evaluaron 118 introducciones del género Lycopersicon, en el Centro Experimental de la Universidad Nacional Sede Palmira. Se utilizó el diseño experimental de Bloques al azar con dos repeticiones; la parcela experimental estuvo constituida por seis plantas. Se estudiaron nueve caracteres relacionados con la planta, diez caracteres relacionados con el fruto, componentes del rendimiento y presencia o ausencia de plagas y enfermedades. Se encontró gran variabilidad para la mayoría de los caracteres. Las variedades de la especie cultivada, L. esculentum, presentaron las mayores producciones por planta y el mayor tamaño de fruto. Las especies silvestres; presentaron mayor resistencia a plagas y enfermedades. Se destacaron los siguientes variedades de L. esculentum por presentar altas producciones y tolerancia a plagas y enfermedades: ADB 18, ADB 400, 1600, 1601 Y Rio Fuego.</p>
<p>118 accessions of the genus Lycopersicon were characterized and evaluated to determinate the genetic potential, using the IBPGR descriptors. The experiment was conducted, using a complete random design and two repetitions. Characteristics concerned to the plant, fruit, yield components and resistence to insects and disease was studied. Important fenotipic differences were founded. The varieties of the cultivated specie L. esculentum, showed heigh productions per plant and heigh average fruit weight. The wild accessions showed heigh resistence to the insects and pathogens. ADBI8, ADB 400, 1600, 1601 and Rio Fuego accessions of the L. esculentum showd heigh productions per plant and heigh resistence to the insects and pathogens.</p>
