Title A name given to the resource Caracterización Citogenética de Cinco Genotipos de Papa Criolla, Solanum phureja (Juz. et Buk.) Cytogenetic Characterization of Five 'Criolla' Potato Genotypes, Solanum phureja (Juz. et Buk.) Creator An entity primarily responsible for making the resource Juan Gonzalo Morales Osorio, Tiani Melissa Gómez Pulgarín, Juan Bautista López Ortiz, Rosana Pineda Tuirán, Leonardo Fabio Galindo López, Rafael Arango Isaza Description An account of the resource Resumen. El cultivo de la papa ocupa el cuarto lugar en el mundo en importancia después del arroz, trigo y maíz. La papa criolla (Solanum phureja) posee características valiosas desde el punto de vista culinario y nutricional, por su alto contenido de vitaminas, minerales, fibra y calidad de proteína. Colombia es un centro de diversidad y origen de papas criollas, lo que representa un enorme potencial de recurso genético para el fitomejoramiento. En la Universidad Nacional de Colombia se conserva el banco de germoplasma de papas criollas de Colombia. El estudio de los cariotipos es importante para entender las bases genéticas que apoyan los cruces que se realizan en los programas de mejoramiento. A pesar de la importancia de este recurso, la caracterización de los cariotipos de las accesiones no ha sido realizada completamente. En este estudio se caracterizaron dos materiales de la colección de S. phureja y tres provenientes de la F1 del cruce de un genotipo resistente y otro susceptible a la enfermedad conocida como gota de la papa. El análisis comparativo permitió identificar diferencias en la morfología celular, dos niveles de ploidía (diploide y triploide), con dos variaciones aneugénicas (hipodiploide y trisomía doble) y cuatro números cromosómicos (18, 24, 26 y 36) para los cinco genotipos evaluados.Abstract. Potato crop is forth in importance worldwide after rice, wheat, and corn. Diploid potato cv. Criolla (Solanum phureja) shows highly desired culinary and nutritional characteristics, such as vitamins, minerals, fiber and protein quality. Colombia is a diversity and origin center of diploid potatoes cv. Criolla, which represents an enormous genetic resource potential for plant breeding. At Universidad Nacional de Colombia the potato 'criollas' germplasm bank is mantained. Karyotype analysis is important for understanding genetic basis of plant breeding. Despite the importance of this resource karyotype analysis of this collection has not been completed. In this study two accesions of the S. phureja collection and three genotypes from a F1 obtained from a cross between a late blight disease resistant and a susceptible genotype were characterized. Comparative analysis allowed the identification of differences in the cellular morphology, two ploidy levels (diploid and triploid) with aneugenic variations (hypodiploidy and double trisomy), and four chromosome numbers (18, 24, 26 y 36) for the five genotypes evaluated.
