Written by Georgeta DICU, Stelica CRISTEA

The current challenge faced by the breeders and maize growers worldwide is the pressure determined by the climate changes causing the expansion of desertification phenomenon and aggravating the draught in soil and the atmospheric heat. Considering these aspects, for market introduction of the new maize hybrids improved in terms of their main characters, breeders have perfected and developed doubled-haploid technology, so now all the multinational companies use this technology widely in obtaining doubled-haploid lines. The aim of this paper is to present the doubled-haploid parent lines and hybrids obtained through using doubledhaploid technology in maize breeding program. In this respect, there were used Procera Haploid Inducers (PHI) which have been obtained into Procera Genetics maize breeding program. Researches were conducted within the maize breeding fields belonging to the Procera Genetics Ltd Company.
