A blueberry (Vaccinium spp.) crop ontology to enable standardized phenotyping for blueberry breeding and research Breeding programs around the world continually collect data on large numbers of individuals. To be able to combine distantly collected datasets, communities have been coming together to develop standard operating procedures for data collection and measurement. One such method is a crop ontology, or ... Insecticidal activity of Jatropha extracts against the azalea lace bug, Stephanitis pyrioides (Hemiptera: Tingidae) We assessed bioactivity of ethanolic extracts from 35 species of Jatropha against an ornamental plant pest, the azalea lace bug, Stephanitis pyrioides (Scott). Jatropha extracts were prepared by air-drying stem, root, or whole plant material, grinding the tissue into a fine powder, adding 70% ethano... Combining high throughput phenotyping and multivariate analysis to assess fruit quality traits in southern highbush blueberry (V. corymbosum interspecific hybrids) germplasm collection Breeding blueberry cultivars with enhanced fruit quality requires simple, accurate and cost-effective assays to select individuals from segregating populations. In this study, berry diameter, berry weight, firmness, pH, total polyphenol, total acids, D- glucose, D-fructose, total glucose, and total ... 'USDA-Spiers' rabbiteye blueberry U*SDA-Spiers’ is a new hexaploid blueberry (Vaccinium hybrid ) developed by the United States Department of Agriculture-Agricultural Research Service and resulted from crosses among diverse blueberry germplasm and species including V. virgatum (rabbiteye blueberry) with V. constablei, V. corymbosu... Insecticidal activity of jatropha extracts against the azalea lace bug, stephanitis pyrioides (Hemiptera: Tingidae) We assessed insecticidal activity of ethanolic extracts from 35 species of Jatropha against an ornamental plant pest, the azalea lace bug, Stephanitis pyrioides (Scott). Fresh shoots and roots were harvested, air-dried, and processed to a fine powder. Ethanolic extracts were then prepared, emulsifie... Genetic diversity and pedigree analysis of muscadine grapes (Vitis rotundifolia) using SSR markers Muscadine grape (Vitis rotundifolia) was the first native North American grape to be domesticated. Over the last century breeding programs have created a large collection of muscadine cultivars. They are normally identified by comparing morphological traits and checking breeding records, which are ... Genetic diversity and pedigree analysis of muscadine grapes (Vitis rotundifolia) using SSR markers Muscadine grape (Vitis rotundifolia) was the first native North American grape to be dometsicated. Over the last century breeding programs have created a large collection of muscadine cultivars. They are normally identified by comaring morphological traits and checking breeding records, which are ... Evaluating global Vaccinium germplasm for resistance against invasive Drosophila suzukii (Diptera: Drosophilidae) Integrated Pest Management (IPM) of spotted wing Drosophila (SWD) in fruits and berries emphasizes biological, cultural, and chemical control. Little research has focussed on genetic control via host plant resistance. Identifying resistant germplasm and patterns of host plant resistance are crucial ... Determination of nuclear DNA content, ploidy, and FISH location of ribosomal DNA in Hibiscus hamabo Hibiscus hamabo Sieb.et Zucc, a deciduous shrub or tree, is an important semi-mangrove plant with golden yellow flowers. The plant is also cultivated for its fiber and grown as an ornamental. It is halophytic and considered one of the best afforestation trees used in reclamation programs in urban an... Characterization and pathogenicity of stem blight complex isolates associated with stem blight disease on Vaccinium species Species of Botryosphaeria and Neofusicoccum are major pathogens of blueberry worldwide. Accurate identification of these species is essential for developing effective management practices. A multigene sequencing strategy was used to distinguish between six isolates collected from two different regio... Multi-year evaluation of stilbene levels among selected muscadine grape cultivars Stilbenes, piceid resveratrol, viniferous and pterostilbene can differ significantly among grape cultivars and years due to variation in environmental conditions amd subsequent stresses encountered during a year. This study evaluated diverse muscadine grape cultivars for their ability to consistent... Erythritol and two of its derivatives reduce survival and reproductive rate of a serious blueberry pest, Drosophila suzukii (Diptera: Drosophilidae) Effective control of D. suzukii during harvest requires weekly applications of low-residual, broad-spectrum insecticides unavailable for organic farming. A novel ingestible insecticide, a 4-carbon polyol, mesoerythritol (erythritol), was found to kill 75% to 100% of larval and aduld SWD. However, me... ‘Muffin Man’ an edible ornamental rabbiteye blueberry The rabbiteye blueberry (Vaccinium virgatum Aiton 2n = 6x = 72) is commercially important in the southeastern United States because of its adaptability to prevalent biotic and abiotic stresses. There is a growing interest in edible landscaping as alternative to conventional landscapes. ‘Muffin Man’ ... Reaction of different vaccinium species to the blueberry leaf rust pathogen Thekopsora minima Blueberry leaf rust caused by Thekopsora minima, is a serious threat to blueberry production. To investigate the host range and characterize new sources of resistance, 15 southern highbush accessions, two interspecific hybrids (Vaccinium spp.), and accessions from five diploid Vaccinium species were... Susceptibility of bunch grape and muscadine cultivars to berry splitting and spotted-wing Drosophila oviposition One of the main disorders that widely reduces fruit quality and commercial value is fruit splitting. Fruit splitting is a physiological disorder that produces surface cracks that promotes disease and insect damage. Moreover, the spotted wing Drosophila (SWD), Drosophila suzukii (Matsumura), is a spe... Laboratory assessment of erythritol derivatives on the survival and reproductive rate of Drosophila suzukii (Diptera: Drosophilidae) Drosophila suzukii (Matsumura) is a vinegar fly species native to Asia. Since its accidental introduction into the United States in 2008, this fly has reduced annual berry yields anywhere from 6% – 100%. Controlling the size of D. suzukii populations during harvest requires weekly applications of lo... Characterization of titratable acids, phenolic compounds, and antioxidant activities of wines made from eight Mississippi-grown muscadine varieties during fermentation Muscadine grape (vitis rotundifolia) Michx.) and its wine products are becoming more acceptable due to potential health benefits associated with high concentrations of phenolic compounds. In this research, wines made from eight high-yielding muscadine grape varieties grown in Mississippi were compa... Variation in nuclear DNA content and chromosome numbers in blueberry Commercial blueberry production in the U.S. relies on cultivars derived from combinations of different blueberry species. Interspecific hybridization continues to be a vital strategy for blueberry breeding, especially in regards to improving abiotic and biotic stress tolerance to expand the range of... Erythritol and Lufenuron detrimentally alter age structure of Wild Spotted Wing Drosophila (SWD) Drosophila suzukii (Diptera: Drosophilidae) populations in blueberry and blackberry We report on the efficacy of 0.5 M (61,000 ppm) Erythritol (E) in Truvia Baking Blend®, 10 ppm Lufenuron (L), and their combination (LE) to reduce egg and larval densities of wild populations of spotted wing Drosophila, Drosophila suzukii (Matsumura) (SWD) infesting fields of rabbiteye blueberries (... Novel formulation of gibberellic acid and coconut oil fatty acids to enhance rabbiteye blueberry maturation, berry size, and yield This paper provides a summary of results presented in a much more comprehensive article (Sampson et al. 2014). Specifics regarding methods and statistical procedures can be found in Sampson et al. 2014. Here, we summarize these results for popular cultivars of rabbiteye blueberry (V. virgatum syn. a...
