The California Freestone Peach Association (CFPA)[2] and California Canning Peach Association/California Cling Peach Board (CCPA)[2][3] represent the industry.[4] (Although the CFPA is a separate incorporation, it has always been operated by the CCPA's staff.) The overwhelming majority of the country's peaches are grown here, in 2020[update] 468,000 short tons (425,000 t) for sales of $308.3 million.[5] Since 1980 the total value of the harvest has been slightly increasing.[5] The acreage (hectares) planted in peach has been declining however, down to 73,000 acres (30,000 ha) as of 2020[update].[5]
Economics
editIn 2014, California lead US peach production, followed by South Carolina, then Georgia.[6]
As of 2021[update] cling deliveries for processing purposes have been on a downward trend for years.[7] From 430,000 short tons (390,000 t) in 2010, delivered tonnage declined to 225,000 short tons (204,000 t) in 2021.[7] Cling yield shows no clear trend over the same time, bouncing between 18.1 short tons per acre (41 t/ha) and 15.3 short tons per acre (34 t/ha).[7]
Prices have been trending mostly upward, from $317 per short ton ($349/t) in 2012 to $518 per short ton ($571/t).[7]
CCPA expects 2022 deliveries to be between 214,200–232,400 short tons (194,300–210,800 t) from a yield of 15.3–16.6 short tons per acre (34–37 t/ha).[7]
Breeding of peach
editUCD hosts one of the major breeding programs in the country.[8] Most of the private breeding programs for peach in the country are found in California, with a significant amount of the public breeding also being performed here but also elsewhere in the country.[8]
