| 1Some production seasons are longer than seven months, but only
October-through-April prices are quoted for all five of these regions.
2Quoted prices may be fresh or CA storage, sometimes both. January prices used here are those that best fit the 7-month price trend shown for each year and region. Prices have been marked with an (*) if they are CA quotes. All October-December prices are fresh; February-April prices are CA. 3Tray packs are 42-lb. bushels. Film bag prices are for twelve 3-lb. bags. These are the only units priced for the entire period in their respective production regions. 4Prices in parentheses are estimated.
