Doubled Haploid Parthenogenetic Production of Melon 'Piel de Sapo'.

Parthenogenesis is the main technique to produce doubled haploid lines in melon. Although parthenogenesis is a genotype-dependent process and melon has a huge genotypic diversity, we developed a successful protocol for haploid embryo production via pollination with irradiated pollen and a protocol for chromosome doubling of haploid plants of 'Piel de Sapo' genotypes. 'Piel de sapo' genotype has lower efficiencies during the process in comparison with other genotypes, for instance, of the agrestis subspecies. Nevertheless, the doubled haploid lines produced have a great potential as pure parentals for hybrid seed production.
