In the last four decades of the twentieth century the use of sweetpotato was diversified beyond their classification as subsistence, food security, and famine-relief crop. In developing countries they serve both as human food and for feeding livestock. In Western countries they appeal to health conscious consumers because of their nutritional aspects. The sweetpotato is very high in nutritive value, and merits wider use on this account alone. The book has 2 parts. A general one giving up-to-date information on the history, botany, cultivars, genetic engineering, propagation, diseases and pests, nutritional data and marketing; and a second part presenting data on sweetpotato growing practices in different areas of the world. The information should be useful to researchers, practitioners and crop administrators in different countries.

To review the priorities for sweet potato germ plasm exploration and collection; To determine the best strategies for sweet potato germ plasm conservation; To establish guidelines for evaluations in the sweet potato collection; To set out strategies for utilizing these genetic resources and establish CIP's breeding priorities; To determine CIP's comparative advantage for research amongst what other institutions are already accomplishing.

Horticulture Reviews is an open-ended, serial continuation series of review articles on research in commercial horticulture crops. This detailed analysis bridges the gap between the specialized researcher and the broader community of plant scientists.

This comprehensive work discusses those factors which contribute to the overall quality of the major vegetables grown in North America for the fresh market as well as methods for storing and preserving these crops. The qualities which determine the suitability of a crop for processing is also discussed since the majority of vegetables, with the exception of lettuce and celery, are processed for the retail market. The selection of vegetables is based on their economic importance although several others are included for completion.
