Dr. Wolfgang J. Grüneberg

Wolfgang J. Grüneberg was born in Hannover / Germany in 1960. In his childhood he spent with his parents several years oversea. He made his master farmer, studied agriculture, and made his diploma under supervisor of Prof. Röbbelen in Göttingen / Germany. In Hannover he worked on a position giving statistic support to students and completed his PhD on “Multi-stage selection in segregating generations of self-fertilizing crops” under supervision of Prof. Weber and Prof. Wricke. As a postdoc in Göttingen he gave statistic lectures and worked on index selection as well as the root crop yam bean. Further experience he gathered on basis of his work for two private breeding companies. Since 2004 Wolfgang J. Grüneberg works for CIP as a senior sweetpotato breeder with research interest in breeding methods, breeding efficiency, genetic gains for sweetpotato and other RTB crops, including the yam bean. His team developed an accelerated breeding scheme for clonally propagated crops which reduces the time needed to get a clone into variety release from 8-10 years to 4-5 years, launched several widely adapted high yielding OFSP clones such as Benjamin (CIP105085.2) and Shokhin (CIP106603.1), and completed the first reciprocal recurrent selection cycle in sweetpotato population hybrid breeding.
