Narrow-leaved lupine (Lupinus angustifolius L.) is a cultivated multipurpose species with a very short history of domestication. It is used as a green manure, and for feed and food. This crop shows good prospects for use in pharmacology and as a source of fish feeds in aquaculture. However, its genetic potential for the development of productive and adaptable cultivars is far from being realized. For crop species, the genetic base of the cultivated gene pool has repeatedly been shown as being much narrower than that of the wild gene pool. Therefore, efficient utilization of a species’ genetic resources is important for the crop’s further improvement. Analyzing the information on the germplasm collections preserved in national gene banks can help perceive the worldwide diversity of L. angustifolius genetic resources and understand how they are studied and used. In this context, the data on the narrow-leaved lupine collection held by VIR are presented: its size and composition, the breeding status of accessions, methods of studying and disclosing intraspecific differentiation, the classifications used, and the comparison of this information with available data on other collections. It appeared that VIR’s collection of narrow-leaved lupine, ranking as the world’s second largest, differed significantly from others by the prevalence of advanced cultivars and breeding material in it, while wild accessions prevailed in most collections. The importance of the wild gene pool for the narrow-leaved lupine breeding in Australia, the world leader in lupine production, is highlighted. The need to get an insight into the species’ ecogeographic diversity in order to develop cultivars adaptable to certain cultivation conditions is shown. The data on the testing of VIR’s collection for main crop characters valuable for breeders are presented. Special attention is paid to the study of accessions with limited branching as a promising gene pool for cultivation in relatively northern regions of Russia. They demonstrate lower but more stable productivity, and suitability for cultivation in planting patterns, which has a number of agronomic advantages. Analyzing the work with narrow-leaved lupine genetic resources in different national gene banks over the world helps shape the prospects of further activities with VIR’s collection as the only source of promising material for domestic breeding.

Modern breeding of sunflower (Helianthus annuus L.), which started 100 years ago, increased the number and the diversity of cultivated forms. In addition, for more than 50 years, wild sunflower and other Helianthus species have been collected in North America where they all originated. Collections of both cultivated and wild forms are maintained in gene banks in many countries where sunflower is an important crop, with some specificity according to the availability of germplasm and to local research and breeding programmes. Cultivated material includes land races, open pollinated varieties, synthetics and inbred lines. The majority of wild accessions are ecotypes of wild Helianthus annuus, but also 52 other species of Helianthus and a few related genera. The activities of three gene banks, in USA, France and Serbia, are described in detail, supplemented by data from seven other countries. Past and future uses of the genetic resources for environmental adaptation and breeding are discussed in relation to genomic and improved phenotypic knowledge of the cultivated and wild accessions available in the gene banks.

Practicable Method

Plant genetic resources are vital in safeguarding and increasing crop production and enhancing human nutrition, particularly in a Man-dominated world. Crop genetic resources are currently under threat of loss for various reasons. Conservation as seed is the most common and practicable method of preserving plant genetic resources. The International Board for Plant Genetic Resources (IBPGR), in cooperation with gene-banks around the world, has created a global network of base-collections. In order to minimize losses of stock in the gene-banks, standards were developed in 1985 and base-collections were assessed against them.

Cultivated Species

Abstract Cultivated species, on which humankind depends for survival, have been created by farmers that have crossed and selected wild plants and developed landraces. Early in 20th century, the theory of Centers of Origin of Cultivated Plants was proposed by Vavilov. He also warned the world about the loss of plant genetic diversity due to the dominance of a small number of genetically similar crops, a fact that help starting a movement for the conservation of plant genetic resources. From this time, several strategies and institutions were established around the world to act in plant genetic resources (PGR) conservation. In Brazil, a remarkable player in PGR conservation, some institutions conserve several crop species as well as their wild relatives and other socio-economically valuable plant species. In this paper we present the status of PGR conservation in Brazil as well as initiatives and laws aiming at respecting, preserving and maintaining associated indigenous and local knowledge, in the context of the target 9 of the Global Strategy for Plant Conservation.

Secale Cereale L

Abstract Common rye (Secale cereale L.) is one of the most important cereals in Europe. Nevertheless, its germplasm collections are among the least numerous compared with cereals. There are only about 27,000 Secale accessions in 70 gene banks around the world. Despite extensive research on the molecular characterization of genetic resources, only a fraction of this collection has been described. The main objective of the presented study was to perform genotypic and phenotypic characterization of an obsolete gene pool represented by 100 accessions originated from 28 countries around the world and preserved in the gene bank of the Polish Academy of Sciences Botanical Garden – Center for Biological Diversity Conservation in Powsin. Genetic analysis using simple sequence repeat markers showed that the obsolete gene pool is relatively large. This indicates that different sources of variability were used in breeding programs. However, the genetic variation is in no way related to the place of origin. Despite the great differences in the genetic make-up, the collection showed a broadly common phenotype. This could result in a low level of interest among breeders in the stored germplasm, undervalued as a source of important but not easily observable traits, e.g., high disease resistance, which was found in some accessions.

The first linguistic description of RN was published by Olaf Broch in German in 1927 in Archiv für slavishe Philologie and in the same year also in Norwegian, at the request of the editor of the Norwegian philological journal Maal og Minne. In 1930 he published the RN texts which were known then and which he had used as a basis for the description of 1927. Broch's interest in RN was concentrated on a pure description of this phenomenon, by him characterized as "a kind of language [...] a mixture of different constituents like the ones we know from different parts of the world under more or less the same conditions». We have passed through a period of comparing RN to other pidgins, establishing RN as a grammatical system with simple morphology, with a syntax that is far from being without rules, but its syntactical possibilities are restricted, as in other pidgins. The history of RN shows that as long as RN was the only means of communication between Norwegians and Russians in Northern Norway the assessment was positive, but when Norwegian merchants started learning Russian proper, RN lost its status as "the fourth language" in Northern Norway, and was characterized in the same derogatory way as colonial pidgins. RN, however, differs from them, in having a special status as a dual-sourced pidgin, while most Atlantic and Pacific pidgin, creoloid and post-creoloid languages have a single main source.This seems to stimulate to more extensive studies into the features of the pidgin and contact languages of the Arctic and the northern regions. Such investigations can hopefully lead to important modifications and necessary redefinitions of the theoretical models employed in pidgin and creole studies.

Refugee Experience

Filistin tarihinde yaşanan 1948 ve 1967 savaşları, binlerce Filistinlinin başka ülkelere göç etmesine neden olmuştur. Günümüzde, dünya genelinde yaşayan Filistinli mülteci sayısının beş milyonu aştığı tahmin edilmektedir. Ülkelerine geri dönemeyen Filistinlilerin mültecilik deneyimleri uzun bir geçmişe sahiptir ve köklerinden koparılma duygusu ile iç içe geçmiştir. Mersin’de bulunan Filistinlilerin zorunlu olarak çıktıkları göç yollarında yaşadıklarının ve mülteci olarak günlük hayatta karşılaştıkları zorlukların Filistinli kimlikleri üzerindeki etkisi sözlü tarih yöntemi ile incelenmiştir. Farklı kuşaklardan sekiz Filistinli mülteci ile yapılan görüşmelerde, dünyanın farklı bölgelerinde mülteci olarak yaşama deneyiminin, Filistinlilerin ulusal bağlılıklarına zarar vermediği görülmüştür. Filistin, mültecilerin yaşamlarında gelenekler, değerler ve duygusal bağlar ile devam etmektedir. Mültecilerin Filistin’den ayrılırken yanlarına aldıkları anahtar, tapu ve toprak gibi nesnelerin saklanıyor olması, Filistin’e olan bağlılığın devam ettiğinin işaretlerinden biridir.ABSTRACT IN ENGLISHPalestinian refugees’ lives in MersinIn the history of Palestine, 1948 and 1967 wars have caused fleeing of thousands of Palestinians to other countries. At the present time, its estimated that the number of Palestinian refugees worldwide exceeds five million. The refugee experience of Palestinians who can not return their homeland has a long history and intertwine with feeling of deracination. Oral history interviews were conducted on the effects of the displacement and struggles of daily life as a refugee on the identity of Palestinians who have been living in Mersin (city of Turkey). After interviews were conducted with eight refugees from different generations concluded that being a refugee in the various parts of the world have not destroyed the national entity of the Palestinians. Palestine has preserved in refugees’ life with its traditions, its values, and its emotional bonds. Keeping keys, deeds and soil which they took with them when they departed from Palestine, proving their belonging to Palestine.
