| Animal products traceability has acquired considerable importance as a security measure in EEC member countries since the food crisis of the mid-nineties. This has led to reinforcing the capacity to manage cattle product quality, with traceability emerging as the main tool to prevent risks to product security and quality as demanded by consumers in developed countries. The practical application of a traceability system for beef, based on molecular markers requires the election of a panel of microsatellites, as well as the optimization of methods of sampling and DNA analysis. In this work, a traceability system for beef based on a panel of 10 microsatellites markers was implemented. Different biological samples were evaluated, such as hair, blood, tissue... |

| Los marcadores moleculares basados en Secuencias Simples Repetidas (SSR) constituyen una herramienta altamente eficaz para la identificación de genotipos de papa (Solanum tuberosum L.) y pueden ser de gran utilidad en la conservación y manejo de germoplasma. Con el propósito de incorporar esta tecnología al Programa de Mejoramiento de Papa del Instituto de Investigaciones Agropecuarias (INIA) de Chile, se evaluó un grupo de 26 marcadores SSR sobre una muestra de 71 genotipos de papa. Cada marcador se caracterizó según su número de alelos y sus respectivas combinaciones, calidad de lectura, contenido de información polimórfica (PIC) y poder discriminatorio (D). Del total sólo 21 marcadores SSR mostraron productos legibles con un número de alelos que varió... |
