Cucumber is a profitable commercial crop over a large area of California. This publication gives tips on planting, cultivating, and marketing.

Surface mulches are widely used in the production of strawberries and certain high-value vegetable crops. Reflective plastic and some cover crop mulches share similar features in crop production: insect and disease management, weed management, fertilizer availability, and water conservation. For production practices using either polyethylene or cover crop mulches to be successful, production goals must be matched with management know how and experience.

By October 2009, all 50 states had implemented a revised WIC program with produce vouchers for millions of eligible families. USDA economists had projected the vouchers would raise net farm revenues by $76 million. In response to such a significant policy change and market opportunity, a UC Agriculture and Natural Resources Cooperative Extension team of researchers conducted a pilot project to test the ability of small farms to market produce locally to WIC-authorized stores known as A-50 vendors. They also interviewed store owners and produce distributors to determine how produce was entering the supply chain to the A-50 vendors. The pilot project was not successful in helping small growers enter the supply chain. The analysis indicates that it is improbable that small farms will be selling much produce to A-50 vendors; growers’ price expectations are unlikely to be met since these vendors are competing with large retailers. And although the vouchers can be redeemed at farmers markets, very few are because the process is cumbersome for growers and shoppers.

The analysis of introgression of genomic regions between divergent populations provides an excellent opportunity to determine the genetic basis of reproductive isolation during the early stages of speciation. However, hybridization and subsequent gene flow must be relatively common in order to localize individual loci that resist introgression. In this study, we used next-generation sequencing to study genome-wide patterns of genetic differentiation between two hybridizing subspecies of rabbits (Oryctolagus cuniculus algirus and O. c. cuniculus) that are known to undergo high rates of gene exchange. Our primary objective was to identify specific genes or genomic regions that have resisted introgression and are likely to confer reproductive barriers in natural conditions. On the basis of 326,000 polymorphisms, we found low to moderate overall levels of differentiation between subspecies, and fewer than 200 genomic regions dispersed throughout the genome showing high differentiation consistent with a signature of reduced gene flow. Most differentiated regions were smaller than 200 Kb and contained very few genes. Remarkably, 30 regions were each found to contain a single gene, facilitating the identification of candidate genes underlying reproductive isolation. This gene-level resolution yielded several insights into the genetic basis and architecture of reproductive isolation in rabbits. Regions of high differentiation were enriched on the X-chromosome and near centromeres. Genes lying within differentiated regions were often associated with transcription and epigenetic activities, including chromatin organization, regulation of transcription, and DNA binding. Overall, our results from a naturally hybridizing system share important commonalities with hybrid incompatibility genes identified using laboratory crosses in mice and flies, highlighting general mechanisms underlying the maintenance of reproductive barriers.
