Production of peaches in California

California is the largest grower of peaches in the United States, producing about 70% of the total.



The (CFPA) and  (CCPA)  represent the industry. (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, 468000 ST for sales of $308.3 million. Since 1980 the total value of the harvest has been slightly increasing. The acreage (hectares) planted in peach has been declining however, down to 73000 acre.

Economics
In 2014, California lead US peach production, followed by South Carolina, then Georgia.

cling deliveries for processing purposes have been on a downward trend for years. From 430000 ST in 2010, delivered tonnage declined to 225000 ST in 2021. Cling yield shows no clear trend over the same time, bouncing between 18.1 ST/acre and 15.3 ST/acre.

Prices have been trending mostly upward, from 317 $/ST in 2012 to 518 $/ST.

CCPA expects 2022 deliveries to be between 214200-232,400 ST from a yield of 15.3-16.6 ST/acre.

Breeding of peach
UCD hosts one of the major breeding programs in the country. 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.
