Handbook for the Collection, Preservation, and Characterization of Tropical Forage Germplasm Resources

摘要

This handbook established the procedures for the collection, preservation, and characterization of tropical germ plasm resources. The following steps are outlined in individual chapters: preparation for the collection trip; germ plasm collection in the field; description of the collection site; soil sample collection and procedures; collection of Rhizobium strains; and collection and preservation of insects and pathogenic organisms. General and technical equipment needed for a collection trip is discussed, as are basic considerations concerning where and when to look for germ plasms.
