Solano walnut varietyCourtesy University of California, DavisThe Solano walnut varietyThe University of California, Davis, walnut breeding program recently released the Solano variety.

The newcomer has light-colored kernels, high yields, large nuts and solid, attractive shells, according to a recent grower newsletter.

It has leafing, flowering and harvest dates similar to Vina, but Solano has improved kernel color and leaf structure and is well suited to the Sacramento Valley.

Nuts of Solano average 14.6 grams with 55 percent kernel weight.

Kernals average 93 percent light and extra light in trials.

The shell and seal strength is tight enough to also be used as in-shell.

Previously known as UC95-011-16, Solano originated as a cross between a Tulare sibling and Chico.

It has bee in regional blocks in Butte, Yolo and Fresno counties and in grower trials in Tehama, Butte, Sutter and Yolo counties.

Solano leafs out a week later than Payne, Serr or Ashley, and catkins shed before the female bloom

It harvests ahead of Tulare and Howard and more than two weeks before Chandler.

Solano's timing is similar to that of Vina, but it has a more easily managed canopy, better kernel quality and larger nuts.

Canopy structure on grower trails has been upright and without limb breakage.

Tree size at maturity is expected to be similar to Chandler. Overlapping pollen sources include Tulare, Chandler and Howard.

Because Chandler leafs out later, it is expected to have less exposure to spring rains and therefore less susceptibility to blight.
