description The Research Group of Tropical Plant Breeding of Magdalena University has several corn introductions original from the Colombian Caribbean; 13 of them were selected, which were donated by the National University of Colombia Campus Palmira, with original passport data from the department of Magdalena. The introductions were characterized to study the phenotypic variability. Sowing was done at the Center for Agricultural and Forestry Development of the University of Magdalena, located in the city of Santa Marta, following a randomized complete blocks design with three replications; 20 plants per introduction were planted and 5 of them were assessed per experimental unit. Twenty eight descriptors were studied. Analyses of variance, frequencies main component, multiple, discriminant, and cluster were performed. Statistical differences among introductions for most of the variables were detected and it is considered as an indicator of diversity. The main components and cluster divided the sample in five sets; there was a gradual and continuous difference in characters inside the groups. The genotypes showed a genetic similarity with introduction 91, the largest genetic distance was with the Synko commercial hybrid. By sorting introductions by municipality, the trend to point out Foundation as the starting point was a trend and is likely that dispersion occurred from there.

El Grupo de Investigación Mejoramiento Genético Vegetal Tropicales de la Universidad del Magdalena posee varias introducciones de maíz originarias del Caribe colombiano; se seleccionaron 13, las cuales fueron donadas por la Universidad Nacional de Colombia sede Palmira, con pasaporte del departamento del Magdalena. Las introducciones se caracterizaron para estudiar la variabilidad fenotípica.  La siembra se realizó en el Centro de Desarrollo Agrícola y Forestal de la Universidad del Magdalena, ubicada en la ciudad de Santa Marta; bajo un diseño de bloques completos al azar con tres repeticiones; se sembraron 20 plantas por introducción y se evaluaron 5 de ellas por unidad experimental y se estudiaron 28 caracteres morfológicos. Se realizó un análisis de varianza, de frecuencias, de componentes principales, discriminante y de agrupamiento. Este mostró diferencias significativas entre introducciones para la mayoría de las variables, lo que se considera un indicador de diversidad. Los análisis de componentes principales y de agrupamiento, diferenciaron a las muestras en cinco conjuntos; al interior de los grupos se presentó una diferencia gradual y continua de caracteres. Los genotipos mostraron similitud genética con la introducción 91, el mayor distanciamiento genético se dio con el híbrido comercial Synko. El agrupamiento de las introducciones por municipio, mostró la tendencia de ubicar el desplazamiento de las introducciones, desde el municipio de Fundación como punto de partida.

Realizou-se um método de ANOVA, de frequências, de componentes principais, discriminante e de agrupamento.
