2 Significance of plantain as a staple food crop
In sub-Saharan Africa: over 30 million people subsist on bananas as principal source of dietary carbohydrate. Plantain: key component of food security in DRC (1.57 million t y-1) 65% of the produced bananas are plantains. 1st Intern. Confer. on Biodiversity in the Congo Basin Kisangani,6th -10th June 2014
