　　Seed Collection Effort Aims to Safeguard 21 Food Crops (1/2)

A new project will try to protect twenty-one of the world's most important food crops by securing their seeds. Organizers say the project will "rescue" seed collections in developing countries where many gene banks are in poor condition.

This is a joint project of two organizations, the Global Crop Diversity Trust and the United Nations Foundation. Cary Fowler, the director of the trust based in Rome, says it will be the largest such effort ever made.

The aim is to collect seeds or reproductive material from 165000 varieties of the crops. Organizers say the effort will secure more than 95% of the endangered crop diversity represented in gene banks in developing countries.

They say the fight against hunger cannot be won without securing crops that are in danger of being lost. Many of the crops are known as "orphan crops." Orphan crops do not get much attention from modern plant breeders but are especially important in poor countries. These include cassava, sweet potatoes, yams, taro and coconut.
