The Pacific Northwest region of the United States is an important growing region for the production of blueberry ( V. corymbosum L.), blackberry ( Rubus L. subgenus Rubus , Watson), raspberry ( R. idaeus L.), and strawberry ( Fragaria
In Queensland, 80% of strawberry ( Fragaria ×ananassa ) production occurs between Brisbane and the Sunshine Coast with a major concentration in the Wamuran-Caboolture area located ≈50 km north of Brisbane. During the production season, from late
Intensive fruit, ornamental, and vegetable production systems in the United States and elsewhere in the world rely on preplant soil fumigation to control soil-borne pathogens, pests, and weeds. These include strawberry ( Fragaria × ananassa ) and

Intraspecific crossing of `Guardian' and `Midway' cultivated strawberry (Fragaria ×ananassa Duch.) produced a family of genotypes, some of which suppressed root-lesion nematode [Pratylenchus penetrans (Cobb)] population counts and produced large berries and high yield. Unlike `Midway', `Guardian' also suppressed P. penetrans. Among several beach strawberry [Fragaria chiloensis (L.) Duch.] and woodland strawberry (Fragaria virginiana Duch.) genotypes, variation was found in resistance and tolerance to root-lesion nematodes. Three F. chiloensis genotypes showed tolerance, and at least two genotypes may be somewhat resistant. Three F. virginiana genotypes also were tolerant, and three were resistant. Also, one (`Little Cataraqui 4') combined root growth vigor with nematode resistance. We concluded that exploitable genetic diversity in vigor and reaction to root-lesion nematodes exists in wild Fragaria and in F. ×ananassa.
Total U.S. strawberry ( Fragaria × ananassa ) production was estimated to be 1.59 million t from 21,245 ha in 2016 [ National Agricultural Statistics Service (NASS), 2017 ]. About 79% of the U.S. strawberry industry is concentrated in California
Abstract
The ‘Del Norte’ and ‘Yaquina’ clones of Fragaria chiloensis (L.) Duchesne exhibited a high degree of resistance to the strawberry aphid, Chaetosiphon fragaefolii (Cockerell), but a third clone, ‘OR-US 3162’, was very susceptible. Resistance of ‘Del Norte’ was transmitted to progeny when crossed with commercial strawberry cultivars, Fragaria × ananassa Duch. None of 30 commercial strawberry cultivars and advanced selections tested showed resistance to this aphid.
Abstract
Genetic analysis of phosphoglucoisomerase and leucine amino peptidase allozymes clearly indicated that the octoploid cultivated strawberries Fragaria × ananassa Duch. are highly diploidized. A 4-locus genetic model is proposed for the PGI allozymes in the octoploid strawberries commensurate with the genomic structure. The LAP system needs further investigation in order to establish the number of loci and alleles present. The possible adaptive value of the biochemical diversity found in the Fragaria species is discussed.
California accounts for 85% of strawberry ( Fragaria × ananassa , Duch.) production in the United States and ≈20% of worldwide production [ U.S. Environmental Protection Agency (USEPA), 2009a ]. Most of the 16,107 ha under strawberry cultivation in
