Sumario:[EN] Obtaining double haploid plants is a powerful tool for breeding programs, because these plants are 100% homozygous. These pure lines can be used as parental lines, allowing for the production of hybrids. Hybrids are interesting due to their high yield potential and to the presence of hybrid vigor (heterosis). Androgenesis is a rapid and convenient method to produce pure lines for plant breeding because androgenic double haploids reach 100% homozygosity after one in vitro generation, instead of the several generations of inbreeding needed in classical pure line production. Despite of the considerable importance in plant breeding programs, the potential of this technique cannot be fully exploited in many species due to the lack of a reproducibl e and reliable method. Regeneration of androgenic plants in many recalcitrant species, such as eggplant or pepper, occurs indirectly via callus production because embryos arrest in development and transform into calli. Efficient androgenesis is usually ind uced by the application of a stress treatment. There are many different stressing agents, with variable effects among species. The aim of this study is to determine the effect of a novel stressing agent, benzyl alcohol, on the induction of androgenesis in rapeseed, eggplant and pepper
