History Of

Michigan (MI) has a long history of diverse agricultural production. One of the most rapidly expanding and profitable agricultural crops, wine grapes (Vitis vinifera L.), has only been in cultivation across MI since the 1970s. As of 2014 more than 2100 acres of Vitis vinifera were growing statewide. With such success there is a push to rapidly develop more vinifera vineyards across the state. The industry is striving to have 10,000 acres in cultivation by 2024. This study presents a data-driven approach for guiding decision making to make this goal attainable. The study models land suitability across the state using environmental, climate, topographic and land use data to understand the most to least ideal portions of the landscape for vinifera establishment. The models are tested in 17 MI counties. The study found that land suitability for viticulture has expanded and therefore, viticulture can be extended beyond the traditional growing areas. This study suggests that warming temperatures have influenced land suitability and demonstrates the application and utility of GIS-based land suitability modeling in viticulture development. Maps produced in this study provide knowledge of the climate and environmental trends, which is critical when choosing where and what cultivar to grow. With such resources, growers can be better prepared to invest and expand this pivotal agricultural sector.

Grape cultivation is a billion-dollar agricultural sector in California, where invasive or novel pest species can disrupt management practices. We report herein on a new pest associated with California vineyards, the carpentermoth Givira ethela (Neumoegen and Dyar, 1893). Rather than an invasive species, G. ethela appears to be a newly recognized wood-boring pest of Vitis vinifera (L.) in regions of California’s Central Valley, where its initial occurrence has been dated back to, at least, the beginning of the 2000s. The habitus of adult, genitalia and pupa is illustrated. Givira ethela distribution in California is updated including published records and new data. Carpentermoth galleries seem to facilitate the access of Planococcus ficus Signoret, 1875 to vine sap and protection from natural enemies, environmental stresses, and pesticide treatments. Notes on pest status, life history, monitoring practices, natural enemies, and management options on grapes are also discussed. Tools for the Integrated Pest Management of G. ethela should include the correct identification of the insect and its damage, a full understanding of its biology and ecology, the application of monitoring methods, and the identification of economic thresholds and injury levels.

История виноградарства на Дону насчитывает несколько веков, местные сорта винограда многообразны и специфичны. Микросателлитные маркеры широко используются для генотипирования сортов и подвоев винограда, при изучении происхождения сортов и анализе их родословной. Целью исследования было изучение выборки редких и малораспространенных автохтонных донских сортов и сравнение их с другими аборигенными донскими генотипами на основе данных ДНК-анализа. В исследования включены 23 стародавних донских сорта. Генотипирование проводили методом микросателлитного профилирования. В исследовании использовали микросателлитные маркеры (SSR), рекомендованные в качестве основного минимального набора для ДНК-паспортизации сортов вида Vitis vinifera L.: VVMD5, VVMD7, VVMD27, VVS2, VrZAG62 и VrZAG79. По результатам проведенного анализа все изученные образцы показали сорт-специфическую комбинацию аллелей в идентифицированных ДНК-профилях. Количество выявленных аллелей составило в среднем 8 аллелей/локус. Наибольший полиморфизм в исследовании этой группы донских сортов был обнаружен в локусе VVMD5: идентифицировано 10 аллелей на локус, наименьшее - в локусе VrZAG62: 6 аллелей/локус. Основываясь на данных SSR-анализа, степень генетического сходства сортов оценивали с использованием метода UPGMA. Кластерный анализ матрицы генетических дистанций, созданный на основе выявленных значений аллелей в шести микросателлитных локусах исследуемых сортов, определил несколько групп генотипов. Сорт Красностоп золотовский выделился в отдельную ветвь, что указывает на различия между этим генотипом и другими сортами исследуемой выборки. Наивысший уровень генетического сходства наблюдался между следующими парами сортов: Крестовский и Бургундский, Шилохвостый и Мушкетный, Кумшацкий черный и Ефремовский.The history of viticulture on the Don goes back several centuries. Local grapevine varieties are diverse and peculiar. Microsatellite markers are widely used in genotyping grapevine cultivars and rootstocks, in grapevine origin and breeding background analysis. Our study aimed to examine samples of rare and less common autochthonous Don varieties, and compare them with the other aboriginal Don genotypes using DNA data. The study involved 23 traditional Don varieties. The genotyping was done by microsatellite profiling. The study used microsatellite (SSR) markers recommended as the basic minimum set for DNA-certification of the genotypes of Vitis vinifera L.: VVMD5, VVMD7, VVMD27, VVS2, VrZAG62 and VrZAG79. Based on the findings, all the studied samples demonstrated variety-specific combination of alleles in the identified DNA profiles. The number of detected alleles on average was 8 alleles/locus. The greatest polymorphism in the studied group of Don varieties was detected in VVMD5 locus: 10 alleles per locus were identified, the smallest in VrZAG62 locus: 6 alleles/locus. UPGMA method was used to assess the extent of genetic similarity of the varieties based on SSR-genotyping data. Based on determined allele values of the studied varieties, cluster analysis of the genetic distances matrix determined several groups of genotypes. ‘Krasnostop zolotovskiy’ variety stood out as a separate branch, which indicates the difference between this genotype and the other varieties of the studied sampling. The highest level of genetic similarity was observed between the following pairs of varieties: ‘Krestovskiy’ and ‘Burgundskiy’, ‘Shilohvostyi’ and ‘Mushketnyi’, ‘Kumshatskiy chornyi’ and ‘Efremovskiy’.

Societal Problems

Economic development is an important phenomenon that can positively impact societal problems such as poverty, lack of education, and insufficient infrastructure, among other ills. In this regard, technological advances are essential to making better use of resources. The agricultural sector is no exception. With the passage of time, advances in agriculture have allowed processes to be optimized, improving production practices and minimizing risks, by using innovative technologies (Schenkel, Finley, & Chumney, 2012). For this reason, the adoption and use of approaches to protected agricultural production grew steadily in the State of Sinaloa, Mexico during the last century and until today. Such technology assisted significantly in the economic development of the region. This inquiry sought to understand factors and forces that augmented expansion of protected agriculture, especially regarding tomato production, and its advantages compared to traditional systems, as experienced by producers in Sinaloa. Understanding such a phenomenon may provide important implications for improving the economies of similar contexts in need of economic development where agriculture is a viable sector.

Grape Cultivars

222 cultivated (Vitis vinifera) and 22 wild (V. vinifera ssp. sylvestris) grape accessions were analysed for genetic diversity and differentiation at eight microsatellite loci. A total of 94 alleles were detected, with extensive polymorphism among the accessions. Multivariate relationships among accessions revealed 16 genetic groups structured into three clusters, supporting the classical eco-geographic grouping of grape cultivars: occidentalis, pontica and orientalis. French cultivars appeared to be distinct and showed close affinity to the wild progenitor, ssp. sylvestris from south-western France (Pyrenees) and Tunisia, probably reflecting the origin and domestication history of many of the old wine cultivars from France. There was appreciable level of differentiation between table and wine grape cultivars, and the Muscat types were somewhat distinct within the wine grapes. Contingency χ2 analysis indicated significant heterogeneity in allele frequencies among groups at all loci. The observed heterozygosities for different groups ranged from 0·625 to 0·9 with an overall average of 0·771. Genetic relationships among groups suggested hierarchical differentiation within cultivated grape. The gene diversity analysis indicated narrow divergence among groups and that most variation was found within groups (∼85%). Partitioning of diversity suggested that the remaining variation is somewhat structured hierarchically at different levels of differentiation. The overall organization of genetic diversity suggests that the germplasm of cultivated grape represents a single complex gene pool and that its structure is determined by strong artificial selection and a vegetative mode of reproduction.

Armenia is an important country of origin of cultivated Vitis vinifera subsp. vinifera and wild Vitis vinifera subsp. sylvestris and has played a key role in the long history of grape cultivation in the Southern Caucasus. The existence of immense grapevine biodiversity in a small territory is strongly linked with unique relief and diverse climate conditions assembled with millennium-lasting cultural and historical context. In the present in-depth study using 25 nSSR markers, 492 samples collected in old vineyards, home gardens, and private collections were genotyped. For verification of cultivar identity, the symbiotic approach combining genotypic and phenotypic characterization for each genotype was carried out. The study provided 221 unique varieties, including 5 mutants, from which 66 were widely grown, neglected or minor autochthonous grapevine varieties, 49 turned out to be new bred cultivars created within the national breeding programs mainly during Soviet Era and 34 were non-Armenian varieties with different countries of origin. No references and corresponding genetic profiles existed for 67 genotypes. Parentage analysis was performed inferring 62 trios with 53 out of them having not been previously reported and 185 half-kinships. Instability of grapevine cultivars was detected, showing allelic variants, with three and in rare cases four alleles at one loci. Obtained results have great importance and revealed that Armenia conserved an extensive grape genetic diversity despite geographical isolation and low material exchange. This gene pool richness represents a huge reservoir of under-explored genetic diversity.
