Resumen
Se realizó un experimento para determinar el nivel de autoincompatibilidad genética en coliflor ‘Criolla’. El estudio se realizó en Cartago, Costa Rica, en campo e invernadero y se comparó la producción de semilla en ambas condiciones durante el periodo entre setiembre de 1990 y mayo de 1991. Las diferencias en producción de semilla fueron significativas y se concluyó que la población muestra un alto nivel de autoincompatibilidad y que se debe trabajar con poblaciones de tamaño razonable durante el proceso de mejoramiento genético para evitar depresión por endogamia y deriva genética.
In order to evaluate the level of self-incompatibility in a cauliflower land race, an experiment was conducted under greenhouse and field conditions in Cartago, Costa Rica, between September 1990 and May 1991. The selfincompatibility was estimated by the number of seeds/silique measured on ten plants with and without the natural pollinators (field and greenhouse respectively). There were statistical differences on seed production between the two treatments and the population showed a high level of self-incompatibility which must be considered in every breeding program in order to avoid genetic drift and endogamy.
