low elevations with climates like those of many warm-temperate regions of the world. Thus, it seems probable that Brazil's experience is demonstrating arracacha's future potential for regions such as North America and southern Europe. People outside Latin America could soon be enjoying these underexploited roots just as the Incas did 500 years ago.

PROSPECTS

Andean Region. This crop is a good candidate for expanded cultivation in its native region. For example, it has been tested in the eastern valleys of the Andes, where it was previously unknown, and it yielded well there. Given research attention, it is likely to become a major product at intermediate elevations throughout the 4,000-km-long Andean region.

Other Developing Areas. Arracacha could become a valuable root crop in all tropical highlands, particularly if improved cultivars and cultural techniques are developed. The potato has already become successful in Nepal and Burundi. Arracacha (and the other Andean tubers) should now be introduced—using recognized quarantine procedures—to the highlands of Asia and Africa for experimental trials. Cultivation should be tested in the highlands and hill country of East Africa, Central Africa, India, Southeast Asia, and similar regions. Remnants of old introductions may still exist in the highlands of Central America and the West Indies; local agronomists should investigate.

As noted, arracacha has received little research attention, but, with modern technology, is being successfully cultivated in Brazil. Many countries of Latin America and elsewhere seem likely to reap direct benefit from this experience.

Industrialized Regions. In North America, Europe, Japan, and other temperate regions, arracacha is likely to become commonplace. The roots should prove highly acceptable to millions of consumers. In the United States, they are already found in Boston's produce markets (shipped from Puerto Rico),3 and locally grown arracacha is available in a few markets in the San Francisco Bay area.4 The plant has also been introduced to Australia.5
