CIMMYT provides a maize Doubled Haploid (DH) Production Service at cost to maize breeding programs in Africa and Latin America at its DH facilities in Kenya and Mexico, cutting the time required to develop homozygous maize lines from three to seven years, using traditional inbreeding down, to just over one year.
DH technology generates pure maize lines in half the time normally required by breeders, and the resulting lines are of a much higher purity. This helps breeders increase the rate of genetic gain, that is, the genetic potential of a crop’s increase in yield over time.
CIMMYT established centralized DH line production facilities for Africa at Kiboko, Kenya. Similar facility is also in operation for Latin America at CIMMYT’s experimental station in Agua Fria, Mexico. Both public and private sector organizations involved in maize germplasm development can access the DH production service by signing a DH service agreement.
