The event is organised by the British Society of Plant Breeders (BSPB) and around 1,400 industry professionals from the global seed industry are expected to attend.
BSPB chief executive Dr Penny Maplestone said: "I cannot recall a more vibrant time for the seeds sector, with a growing recognition that improved varieties, seeds and agronomy are the essential platform for sustainable agriculture to address the global challenges of food security and climate change.
"For business this is a unique opportunity to access the world’s seed industry, with particularly strong representation from Europe, including the emerging markets of Eastern Europe; many members of the seed trade only attend the congress when it is held in Europe, and it will not return until 2013."
She added: "The congress programme includes a strong line-up of expert speakers and covers key issues for the further development of the international seeds industry, while the conference venues and the city of Belfast itself offer an ideal setting for business and networking."
