www.iita.orgA member of CGIAR consortiumConventional breeding: slow and expensivePlaying with ploidy


Unpredictable seed production (3x)

Poor seed/embryo germination

Field Tissue culture Screenhouse Field

First selection after 1-2 years

99.9% of the hybrids discarded in EET

Breeding:New and superior lines developed in the three groups of banana Nutritional quality: Vit A and C, PotassiumFlower biology understoodHeterotic parental combinations identifiedChromosome doubling adopted in IITA East Africa and NARO

Pests and diseases:Efficient bioassays developed for fast screeningBreeding material tested for resistance to major pests and diseases
