The coconut palm is a very important plant in the tropical regions, both as a cash crop and in subsistence agriculture. Although most coconut production is dedicated to copra and its subsequent oil extraction, the number of products that can be obtained from the palm is seemingly limitless. However, the coconut industry has several problems that affect its productivity, especially: the use of unimproved planting material, the old age of existing plantations, and various pests and diseases. This book deals with the most severe of the diseases, lethal yellowing, which has killed millions of coconut palms in Latin America and the Caribbean alone and which, together with related diseases in Africa and possibly India and Southeast Asia, poses a world-wide threat to coconut production. The papers were presented to a symposium on "Lethal Yellowing Research and Practical Aspects", held in Mexico in November 1993. The book should help to maintain the momentum in lethal yellowing research, stimulating further research on coconut palms, an orphan crop having many uses.

The coconut palm occupies a significant place in the world economy as an important subsistence and cash crop in all the areas where it is cultivated. Unfortunately, yields are generally well below potential, despite recent developments with improved planting stock and agronomic practices. Since the 1950s, both aspects have received considerable attention, but the focus is shifting to investigate how the use of recently developed biotechnological techniques can benefit the coconut industry. These papers on coconut biotechnology were presented at a symposium on this subject held in Mexico in December 1997. They describe research in three important areas of this field: molecular markers, diversity and genetic improvement; molecular detection and diagnosis of diseases; and in vitro propagation. They also deal with the impact of biotechnology on the coconut industry, weighing the advantages and pointing out areas where work should be directed to stimulate further research.

The coconut palm occupies a significant place in the world economy as an important subsistence and cash crop in all the areas where it is cultivated. Unfortunately, yields are generally well below potential, despite recent developments with improved planting stock and agronomic practices. In the last 50 years, both aspects have received considerable attention, but the focus is shifting to investigate how the use of recently developed biotechnological techniques can benefit the coconut industry. This volume is the first one published on coconut biotechnology; the papers were presented at a symposium on this subject held in Mexico in December 1997. The book describes recent research in three important areas of this field: (a) molecular markers, diversity and genetic improvement; (b) molecular detection and diagnosis of diseases; and (c) in vitro propagation. It also deals with the impact of biotechnology on the coconut industry, weighing the advantages and pointing out areas where work should be directed to stimulate further research.

When I received an invitation to attend the International Symposium on Lethal Yellowing being organised by the Centro de Investigacion Cientifica de Yucatan (CICy), I was excited and a little nostalgic. During the 1970s, a series of similar symposia had been held under the auspices of the loosely-constituted "International Council on Lethal Yellowing" (ICL Y). These were the years when the MLO cause for L Y was first proposed, a vector was found, the disease was racing across mainland Florida, USA and it was suspected of having jumped to Cozumel. Analogous diseases were also reported to be spreading in Africa and elsewhere. The ICL Y meetings, held approximately every two years, proved to be an immensely valuable forum for all involved in the research and control of L Y. They attracted a very wide cross-section of scientists and practitioners working on L Y, on related diseases, and on palms in general. Many participants of those ICL Y meetings also attended this CICY Symposium. Unfortunately, during the 1980s, as countries learned to live with L Y, most of the national and international funding for L Y research dried up, and so did ICL Y. The present symposium is the only international meeting to have been devoted to L Y since the last meeting of rCLY in 1979. Its convening in Merida is timely.
