Overview

 

Bananas and plantains (Musa) are grown in more than 120 countries throughout the tropics and subtropics, 85% of which are produced by small-scale farmers for home consumption or for sale in local and national markets. As such they sustain rural livelihoods and food security. Musa includes a wide range of types and cultivars, including cooking bananas, plantains and dessert bananas. Cooking banana and plantain provide a staple food for over 400 million people, with great importance in Sub-Saharan Africa.    

 

Fusarium wilt of banana (Fusarium oxysporum f. sp. cubense (Foc)) has widely been considered as one of the most devastating diseases in agricultural history, until resistant banana cultivars replaced susceptible ones in Central America. New outbreaks of the disease in Asia, caused by the highly virulent Foc Tropical race 4 (TR4), have raised concerns that the disease is once again, threatening global banana production. Of particular concern is the threat to food security in Africa, where the East African Highland bananas (EAHB) and plantains form the staple diet and only source of income to millions of Africans.

 

To establish whether EAHB and plantain are resistant to Foc TR4, African and Asian research institutions have decided to evaluate African banana cultivars in Asia under the coordination of Bioversity International, and supported by the Global Crop Diversity Trust. Greenhouse testing of African bananas will be conducted in South Africa, and field trials will be performed in China and Indonesia. The outcome of this project will be of great significance not only to Africans, but also to the Americas, where plantain is widely grown. The research proposed here is a pro-active effort to prepare Africa against the potential introduction of Foc TR4 into the continent, and to select or develop material with resistance to the pathogen.

 

This grant began in April 2010, and progress will be reported later in the year.

    what are the chemical components of foc TR4?
    does liming and zinc application enhances the production of inoculums?
