Resumen

La producción de dihaploides a partir de cultivares tetraploides de élite es clave para los enfoques de mejoramiento tanto tradicionales como novedosos que buscan simplificar la genética de la papa. Para ello, se necesitan inductores haploides (HI) eficaces y ampliamente compatibles. Comparamos PL-4, un nuevo HI desarrollado en el Centro Internacional de la Papa, con los conocidos HI IvP101 e IvP35. Mediante la polinización de líneas de reproducción tetraploides de élite, demostramos que PL-4 se desempeñó significativamente mejor y tuvo una respuesta homogénea independientemente de los antecedentes genéticos de los padres pistilados, en los rasgos de eficiencia más importantes: número de dihaploides por 100 frutos y tasa de inducción de haploides. Además, PL-4 exhibió una proporción reducida de semillas híbridas, un rasgo conveniente para un cribado eficiente. En este contexto, recomendamos PL-4 como un HI mejorado para la comunidad de mejoramiento de la papa.
