Our History

Left to Right—Ken Puryear, Lloyd Joley and Corky Anderson

It was by chance, or possibly fate, that Ken Puryear and Corky Anderson got together in the late 1960s. Ken had an established dental practice, and Corky was farming various row crops. The pistachio industry was virtually non-existent.

They toured the pistachio orchard of a mutual friend, and struck up their own friendship. With a keen interest in this new nut that was peaking many people's curiousity, they planted their first pistachio trees in 1967 and a year later, they started Pioneer. Ken retired from dentistry and the agricultural entrepreneurs formed a partnership which would transform an industry.

Lloyd Joley, circa. 1969

Puryear and Anderson traveled to the Chico Research Station and met with the Director, Mr. Lloyd Joley, who advised them on recommended varieties to plant and how to propagate them. In their first year, a large farming operation arrived on the scene and purchased every available tree. Within thirty days, the same company was back and ordered a similar amount for planting the following year. Instead of becoming pistachio growers, before they new it, they were in the nursery business.

After the first growing season, it was obvious that there was a genuine need to improve the quality of rootstock selections. The seed from Chico was overly hybridized, making it difficult to grow and bud. The pistachio industry in California was also struggling with a devastating fungal disease called Verticillium wilt. What was needed was a heartier rootstock compatible with the Kerman bud that could offer quality, consistency and disease resistance.

These pistachio trees are similar to the first trees produced by Anderson and Puryear

Pioneer Nursery immediately initiated a rootstock development program. Seed was obtained from the research station and elsewhere. The seeds were selected for uniformity of type, vigor, compatibility with the Kerman bud, and wilt resistance. Puryear and Anderson "pioneered" a new combination of rootstock and named it Pioneer Gold. At first, they were reluctant to release this new rootstock, and instead chose to test it. Some growers insisted on buying it before its official introduction. For over a decade Pioneer Gold was considered experimental. The initial harvests of the first trees began in 1975.

The results were a huge success. Pioneer Gold exhibited a heartier root system which produced high quality nuts with the consistency necessary to grow an industry. These first trees are still in production today, and are growing high quality pistachios. Now, more than 30 years after the first trees were planted, Pioneer Gold is the only hybrid pistachio tree that has withstood the test of time. To this day, no rootstock has surpassed the quality of the Pioneer Gold tree, which is why we call it "the Gold Standard" for the pistachio industry.

In 1999, Pioneer Nursery grew over a million trees to meet the orders of growers throughout the Western United States, truly a remarkable record by any standards.

The People

Along with Pioneer Nursery, Ken Puryear and Corky Anderson also own and manage over 2000 acres of pistachio groves near the southern end of California's Central Valley. Their contribution to the industry goes beyond the fact that they patented and now supply the majority of rootstock to pistachio growers. Both have been active in the California Pistachio Commission as well, and have helped build the industry for the benefit of all. As experts in the field of pistachios, they know the problems growers face, because they too are growers.

The following is a brief outline of key employees:
