FOREWORD AND PREFACE

This symposium was part of the XXVIth International Horticultural Congress held in Toronto, Canada from 11-17 August 2002. Subtropical and tropical fruits from crops that have major world trade (citrus, avocado and mango), as well as crops that are still emerging as local dietary supplements were included. The symposium provided a broad overview of all horticultural aspects of these crops. Issues included environmental concerns for major production areas, crops to improve the economic position of small farms, and maintenance of a sustainable food supply in developing countries. Major advances in understanding the genetics, breeding and application of biotechnology to these crops, as well as how climatic and environmental factors affect the productivity and quality of fruit were discussed.
Opportunities were presented for more intense cultivation of several indigenous crops that currently are harvested primarily from wild specimens. Between oral presentations and posters, about 100 papers were given in this 4-day symposium. Presenters came from all populated continents of the world. Crop nutrition, cultural practices, diseases and horticultural means of control, factors influencing fruit quality, and postharvest handling of commodities, also were included in the symposium. The co-conveners thank all the participants for their efforts and the valuable information conveyed to the audience.
