As part of on-going efforts to facilitate the use of DNA markers in maize breeding and diversity studies, during 01-06 February 2008 CIMMYT El Batán held a workshop on “The analysis of molecular data generated from genetic bulked heterogenous populations.” Coordinated by CIMMYT molecular biologist Marilyn Warburton and visiting biometrician Jorge Franco, of the Universidad de la República, Uruguay, the course drew six participants from six different countries, in addition to CIMMYT participants. According to Warburton, the workshop turned out to be of great interest to CIMMYT scientists. “We had three people signed up from outside when we started, and gave certificates to another ten or twelve CIMMYT people in the end,” she says. Participants included Allen Oppong (Ghana), Tunde Golinar (Hungary), Niclas Freitag (Switzerland), Yusuf Mansir (Nigeria), Marlen Huebner (Germany), Guy Davenport (CIMMYT), Trushar Shah (CIMMYT), Miguel Anducho (CIMMYT), Eduardo Hernández (CIMMYT), Jianbing Yan (CIMMYT), Shibin Gao (CIMMYT), Maria Zaharieva (CIMMYT), Claudia Bedoya (CIMMYT), and Aida Zewdu Kebede (Ethiopia).
