Genetic Diversity of Cultivated Tropical Plants

How can plant genetic resources best be preserved, evaluated and exploited? According to which criteria and with which tools should collections representing the genetic diversity of cultivated species be established? This work goes some way towards answering 11 tropical plants: citrus fruits, banana, cocoa, coffee, sugarcane, coconut, rubber, cassava, millet, rice and sorghum. The work also contains three chapters on methodologies: biochemical and molecular marking, data analysis and core collections.
