EWG Breeding Methods - Workshop on Hybrid Wheat

February 6 - 2019 (All day)
University of Hohenheim,


This workshop aims to gather actors from public and private sector already involved or planning to develop hybrid programs to discuss these challenges, identify lock-in in knowledges and possibly organize future cooperative programmes on hybrid wheat breeding.


AGENDA (subject to change)
