| File Information | CITRUS CROPS IN CALIFORNIA mean primarily navel and valencia oranges, lemons, grapefruit, and tangerines, tangelos, and tangors. By the most recent figures available (1998–1999) at the time of this writing, the California Agricultural Statistics Service reports the following total values for these crops: navel oranges $227 million; valencia oranges $188 million; lemons $214 million; grapefruit $81 million; and tangerines et al. $23 million. Altogether that’s about a three-quarter-billion-dollar citrus industry, placing citrus in the top ten of California crops. Three of these—oranges, lemons, and grapefruit— are individually also among the top 30 California export crops. To sustain this productivity and competitiveness in the US by creating new varieties, maintaining the diversity of citrus crops, ensuring healthy trees in the field, and desirable fruit in the marketplace, it is imperative that breeders, researchers, and the industry have access to reliable collections of citrus genetic resources. As this report shows, this has been possible by virtue of an unofficial state ‘system’ for conserving and utilizing citrus genetic resources. This system is comprised of University of California, state, and federal organizations and their interrelationships are documented herein. |
