    Contemporary Agriculture Vol. 67, No. 1, Pp. 1 - 8, 2018. The Serbian Journal of Agricultural Sciences ISSN (Online) 2466-4774 UDC: 63(497.1)(051)-“540.2” www.contagri.info Review paper UDC: 582.542.11 DOI: 10.2478/contagri-2018-0001 AGROBIODIVERSITY GENETIC VARIABILITY UTILIZATION IN ORGANIC FOOD PRODUCTION* Miodrag DIMITRIJEVIĆ1♦, Sofija PETROVIĆ, Borislav BANJAC, Goran BARAĆ, Velimir MLADENOV1 Summary The food production at the global level is about to meet its border. Industrialization of agriculture correlates with an explosive enlargement of human population, during XX and at the beginning of XXI centuries. An ongoing process of environmental erosion has been speeding up during that period, not only in our physical surrounding, but also in biodiversity. A new direction in agricultural food production is in demand. Organic food production has been recognized as the way of providing safety and quality food, preserving the environment in the same time. In the other hand new land areas have to be explored for agricultural use, in order to enhance food quantity to meeting the increasing demand for food. These targets set new requirements in plant breeding. To fulfill these requirements the genetic variability harbored in genetic resources has to be preserved, examined and put to good use. Key words: biodiversity, organic, agriculture, genetics, breeding, agriculture INTRODUCTION The human population is growing in a burst. The World entered 20th Century with about 1.5 billion inhabitants, and left it enriched by more than 6 billion. In just 100 years the increment was three time bigger than in all previous human history. At the moment there is more than 7 billion of us, as UN reported, summarized by Roser and Ortiz- Ospina (2017).

  • Report from Case Studies About on Farm Selection and Seed Production
    DIVERSIFOOD Embedding crop diversity and networking for local high quality food systems Grant agreement n°: 633571 H2020 - Research and Innovation Action Deliverable 4.5 Report from case studies about on farm selection and seed production Due date: M44 Actual submission date: M48 Project start date: March 1st, 2015 Duration: 48 months Workpackage concerned: WP4 Concerned workpackage leader: Riccardo Bocci Lead Beneficiary: INRA Responsible author: Marianna Fenzi Additional author: Nathalie Couix, Laurent Hazard Dissemination level: PU: Public (must be available on the website) CO: Confidential, only for members of the consortium (including the Commission Services) Cl: Classified, as referred to in Commission Decision 2001/844/EC Collective Management of Maize Landraces in France and Italy Abstract In industrialized countries, maize culture is associated with the use of hybrid varieties and industrialized agriculture. Despite the homogeneity of maize landscapes, alternative models of maize production exist. This comparative study is based on farmers collectives from Aquitaine (France) and Veneto (Italy) that manage maize landraces. Since the early 2000s, the Aquitaine group adopted maize landraces from different regions of the world while Veneto groups recovered the "historical" and local maize landraces. In Italy, maize landraces are mainly used for human consumption while in France animal feed represents their principal usage. Each group has developed different strategies to define, distinguish and legitimatize their work on maize landraces within a broader context dominated by commercial hybrids. The Aquitaine and Veneto groups display very different organizational functions, practices, and visions. This diversity reflects different productive systems and priorities. The Aquitaine group focuses on the development of maize diversity and related knowledges.

  • Building the Casaccia Gamma Field. Nuclear Energy, Cold War and the Transnational Circulation of Scientific Knowledge in Italy (1955-1960)
    Building the Casaccia gamma field. Nuclear energy, Cold War and the transnational circulation of scientific knowledge in Italy (1955-1960) Francesco Cassata* The article will focus on the mutagenesis programme in agriculture implemented by the Italian Atomic Energy Commission, starting from 1955, through the establishment of a specific technological and experimental system: the so-called “gamma field”, a piece of agricultural land with a radioisotope of Cobalt-60 at the centre. The Cobalt-60 would emit constant radiation, which would bombard the specimens planted in concentric circles around the source, inducing genetic mutations. The Italian gamma field went into operation in January 1960 at the Casaccia Laboratory, about twenty miles north of Rome, with a radia- tion device made available by the US Government for the Atoms for Peace programme This article will analyse, first of all, how the American experimental model of mutation breeding was translated into the Italian context, becoming instrumental for the establishment of plant genetics within the local academic system; secondly, it will describe how the sociotechnical imaginary embodied by the gamma field was part and parcel of this process of discipline- building and scientific demarcation. Key words: Cold War, Atoms for Peace, Nuclear energy, Agriculture, Plant breeding, Genetics It was a round-shaped field, covering a surface of some six thousand square metres: at the centre, in a hole made of concrete walls, the radiation unit that the United States had donated in 1958 as part of the Atoms for Peace programme. The unit was composed of a lead cylinder that weighed about a ton, which contained a radioactive source: two Cobalt-60 rings, approximately twenty centi- metres long.

  • Historic Role of the Wheat Variety Akakomugi in Southern and Central European Wheat Breeding Programs
    Breeding Science 55 : 253–256 (2005) Review Historic Role of the Wheat Variety Akakomugi in Southern and Central European Wheat Breeding Programs Katarina Borojevic1) and Ksenija Borojevic*2) 1) Faculty of Natural Science, University of Novi Sad, Novi Sad 21000, Serbia & Monte Negro (Former Yugoslavia) 2) Department of Archaeology, Boston University, Boston, MA 02215, USA The old semidwarf, not very attractive, Japanese wheat variety Akakomugi was the source of the dwarfing gene Rht8 and photoperiodic insensitive gene PpD1 to many semidwarf wheat varieties in South and Central Europe in the 20th century. Integrating the Rht8 and PpD1 genes in wheat varieties offered the best oppor- tunities for reducing plant height, accelerating time of flowering, improving grain fill before the onset of dry summer conditions, enhancing spikelet fertility, and consequently increasing yields. Many breeders from South and Central Europe and from the former Soviet Union were creating winter short high yielding wheat varieties without knowing at the time that Akakomugi was the donor of such important genes. At the end of the 20th century, it was discovered that dwarfing gene Rht8 and photoperiodic insensitive gene PpD1 are lo- cated on the short arm of chromosome 2D in wheat. Microsatellite analyses proved that Akakomugi is the source for the Rht8 and PpD1 genes in many short wheat varieties in South and Central Europe. Key Words: Wheat, Akakomugi, Rht8, PpD1, wheat history. Introduction Centenario of Nazareno Strampelli 2000, most of the scien- tists present supposed that the seeds of Akakomugi were In the beginning of the 20th century, the Italian breeder brought by a visitor to Strampelli at the beginning of the 20th Nazareno Strampelli was in charge of wheat breeding in century (according to the personal communication of the Rieti when the project “Bataglia del Grano” (Wheat Battle) senior author).

  • I Georgofili E Le Innovazioni in Agricoltura Dalla Nascita Dell’Accademia Ad Arrigo Serpieri
    ACCADEMIA DEI GEORGOFILI I Georgofili e le innovazioni in agricoltura dalla nascita dell’Accademia ad Arrigo Serpieri Saggio storico di Lucia Bigliazzi – Luciana Bigliazzi Firenze, aprile 2016 1 La pubblicazione è stata realizzata in occasione della Mostra I Georgofili e le innovazioni in agricoltura. Dalla nascita dell’Accademia a Arrigo Serpieri, 5-26 aprile 2016 2 Introduzione L’agricoltura, “Madre di tutte l’Arti, e lor Natura” Affrontare il tema delle “innovazioni in agricoltura” legate al mondo dei Georgofili, significa trattare dei Georgofili stessi, della vita stessa dell’Accademia, della linfa vitale che da oltre 250 anni permea l’essenza stessa dell’istituzione e la sua attività. Il motto assunto a rappresentare la prima Accademia di agricoltura del mondo, “Prosperitati Publicae Augendae” bene evidenzia la volontà dei Georgofili di lavorare per la prosperità pubblica, per mantenerla, migliorarla, incrementarla, non tralasciando alcun campo d’azione. Esemplificativo in merito è da considerarsi l’assetto organizzativo che l’Accademia si dette pochi anni dopo la nascita e così dal Ragguaglio dell’istituzione, reggimento e progressi della Accademia dei Georgofili, del 1756, si evince che l’attività accademica era suddivisa in 8 classi di cui oggetto della prima erano il clima della Toscana, le proprietà dei terreni e la loro esposizione, la coltura dei grani e delle biade, biade; la seconda classe si occupava delle viti, della vendemmia, della fattura e conservazione dei vini; oggetto della terza classe, gli alberi da frutta e non;
