Walnut rootstock trial

Walnut rootstock trial

Researchers survey for nematodes in preparation for walnut planting.

In 2016 Lindcove Research and Extension Center (LREC) will welcome its first nut crop on site.  As part of a statewide Specialty Crops Research Initiative (SCRI) study, a walnut rootstock performance trial will be housed at LREC.  In advance of planting, Elizabeth Fichtner, UCCE farm advisor, and Stephanie Doria, College of the Sequoias intern, sampled the plot for presence of Phytophthora, a pathogen common on both citrus and walnut.  In February 2016, Dr. Andreas Westphal, UC Riverside CE Specialist in Nematology, joined Fichtner to survey the block for nematodes.  The new walnut research plot will house new rootstock genotypes produced by the Walnut Improvement Program at UC Davis for evaluation of performance in the southern San Joaquin Valley.
