Fuente: WIPO "tomato" The present invention relates to a method for generating a doubled haploid inducer plant (DHI), the method comprising providing a first plant which is a haploid inducer (HI) plant, wherein the haploid inducer plant is a maternal haploid inducer or paternal haploid inducer; modifying at least an endogenous gene in the haploid inducer plant that is involved in one or more pathways related a to a process which results in chromosome doubling of haploid cells, thereby obtaining a doubled haploid inducer plant.
