The main purpose of the study was to identify the plant genetic resources (PGRs) affected by shrimp farming and to determine their magnitude of vulnerability. Data were collected from randomly selected 100 respondents, through personal interview, using an interview schedule, at Dumuria upazila of Khulna district, during 16 November 2009 to 15 February 2010. The fruit PGRs were more affected by shrimp farming than that of timber yielding and other types of PGRs. Among the 18-fruit PGRs available, all were endangered, except indigenous velvet apple, Diospyros peregrine (Gaertn.) Gürke, which was in threatened condition. Among the fruit species, banana, Musa acuminate; guava, Psidium guajava L.; jackfruit, Artocarpus heterophyllus Lam.; sapota, Manilkara zapota L. and betel nut, Areca catechu L. were in highly endangered. Among the 17-timber yielding and other plant species, only 7-PGRs were affected by shrimp farming while majority (10-PGRs) had been available in different extents. Among the vulnerable PGRs, bamboo, Bambusa bambos (L.) Voss; flame of the forest, Delonix regia (Boj. ex Hook.) Raf.; teak, Tectona grandis L.f. and banyan, Ficus benghalensis L. were endangered, while Indian ash tree, Lannea coromandelica (Houtt.) Merr.; ipil-ipil, Leucaena leucocephala (Lam.) de Wit and cool mat, Schumannianthus dichotomus (Roxb.) Gagnep. were in threatened condition. In general, the total fruit trees decreased in numbers (-74.17%) after inception of shrimp farming. On the other hand, the total numbers of timber yielding plants increased by 15.45%. From the overall consideration (irrespective of types), the number of plant population decreased (-58.10%) after inception of shrimp farming. It means that the plant species were affected by shrimp farming and became endangered. Int. J. Agril. Res. Innov. Tech. 11(2): 18-26, Dec 2021

Since the 1970s, Portugal has been endeavouring systematic and coordinated efforts for ex situ conservation of plant genetic resources. Portugal maintains in ex situ a large seed collection of cultivated species (cereals, fibres, grain legumes, vegetables), wild species (forages, MAP species), also national clone collections of olive, fruit trees and grapes. In 2011 the Portuguese National Genebank (BPGV) and ISOPLEXIS implemented the GRIN-Global platform, as provides the opportunity to increase data quality, to have long term sustainability for data curation, integrates all collections in one management system optimizing the costs and staff resources. Now, the main objective in Portugal is to implement the Grin Global Platform at the national level to consolidate its National Programme of Plant Genetic Resources (NPPGR) with all national partners directly involved in the conservation of PGR. The main objectives of this communication are: to demonstrate the valuable contribution of the Grin-Global platform to the NPPGR; discuss the development and status of the Portugal’s National Inventory 2018 in EURISCO, analyse the evolution of the amount of passport information in EURISCO from 2015 to 2018; to address the steps that are being taken in Portugal for the Implementation of the Grin-Global Platform at the national level.

Working group of the Department of Plant Conservation of the National Botanical Garden of Georgia (NBGG) have been participating in the global Millennium Seed Bank Partnership, led by the Royal Botanic Gardens, Kew since 2005. During the 2005-2018 period, within the scope of MSB-1 and MSB-2, seeds and herbarium samples of more than 1750 plant species and interspecific taxa, belonging to 107 families and 483 genera (more than 41% of Georgia’s flora) – 348 endemics of Caucasus and 151 endemics of Georgia, have been secured in the National Seed Bank of Georgia (NSB). Seed Bank data are managed in BRAHMS (Department of Plant Sciences of Oxford University). The collection of wild plant species is accompanied by the comprehensive database of geographical, botanical and habitat information. Later phase involves laboratory treatment and germination/viability testing (at least 500 seeds per species) and the long-term deposition and storage (under -20◦C temperature) at the National Seed Bank of Georgia. The duplicates of seed collection and herbarium vouchers are stored at the Millennium Seed Bank of Royal Botanic Gardens, Kew, UK. Germination capacity and viability of collections in NSB is determined before cold storage of seeds, while at the MSB already banked seeds are tested.Keywords: Seed bank; Ex-situ conservation; Plant diversity; Botanical garden; Genetic resources

The fruits of the earth have healed, nurtured, and intrigued humanity throughout history. Cultivated fruit species have complex genome that will continue to require the input of novel genetic resources. Prospecting for wild fruit species will continue. The global nature of science and commerce will drive the demand to expand available genetic resources for fruit improvement. New technologies will enable future explorers to reach remote sites and species. Recent advances, such as geopositioning and remote-communication devices, will be used to a greater degree for targeting specific collection sites and documenting records of origin. The sovereignty of countries over their plant genetic resources, as specified by the Convention on Biological Diversity and the International Treaty on Plant Genetic Resources for Food and Agriculture, will continue to be a cornerstone for negotiating bilateral agreements and plant exchange. Although this could be considered a limitation to plant exploration in some situations, global strategies now in conceptual infancy will be developed to encourage and support ex situ preservation and continued plant exchange for long-term conservation and humanitarian benefit.

The article is dedicated to the mobilization of plant genetic resources from the territories of Indonesia, Sri Lanka (Ceylon) and Nepal to VIR’s collection by means of collecting explorations, germplasm requests and the exchange of accessions. The first, the longest and the only pre-war expedition to Indonesia and Ceylon was undertaken by Prof. V. V. Markovich; it lasted three years (1926–1928). He explored Java, Singapore and Ceylon, where he collected 772 germplasm samples. In 1957, D. V. Ter-Avanesyan, who worked as an agricultural attaché at the USSR Embassy in India, familiarized himself in every detail with plant resources and agriculture in Nepal. The late 1960s were marked by intensification of plant genetic resources introduction and new opportunities to organize regular collecting missions. In the period from 1960 to 1991, there were five plant exploration trips to Indonesia, Sri Lanka (Ceylon) and Nepal. In 1960, D. V. Ter-Avanesyan visited scientific institutions in Java, got acquainted with the main trends in agriculture, and collected 302 plant samples. In 1974, A. G. Lyakhovkin took part in a specialized collecting mission launched to study and collect wild forms and cultivars of rice and various other crops from Nepal. The team visited 16 experiment stations and farms and collected 1170 accessions. In 1985, an expedition team led by E. F. Molchanov collected and studied wild and cultivated forms of subtropical plants in Sri Lanka. The team visited 5 institutes and experiment stations, 3 botanical gardens, and collected 370 accessions. In 1988, another collecting team led by L. A. Burmistrov, whose task was to study the system of nation-wide projects on crop improvement, traveled over four provinces, visited 11 scientific and academic institutions of Nepal, and collected 766 germplasm samples. The last collecting trip to Indonesia was led by N. G. Musatenko in 1991. The team collected 95 varieties and wild forms. In total, the Institute’s collecting and exploration activities in Indonesia, Sri Lanka (Ceylon) and Nepal added 3496 accessions to its collections. In addition to direct collecting in Indonesia, Sri Lanka (Ceylon) and Nepal, VIR has always been replenishing its holdings by seed requests. During the whole pre-war period, from 1925 through 1941, 256 germplasm accessions were added. All in all, from 1948 through 2018, 104 accessions were introduced from Indonesia, Sri Lanka (Ceylon) and Nepal. The greatest number of accessions received by the Institute represented groat crops (over 1400), followed by wheat and barley (458), and industrial crops (627). In total, during the whole period of its existence, the Institute has mobilized 3843 accessions, representing 377 plant species.

Climate change is an unequivocal fact and its impacts are already perceptible today. Climate change will profoundly alter the present conditions of agriculture in almost all countries with variable severity from region to region. On one hand unpredicted changes in climatic parameters are likely to threaten the production and productivity of economically important plant species particularly that of food crops, at the same time agriculture productivity requires significant increase to meet the expected growth in demand for food by the ever increasing world population. Conservation and sustainable use of diversity present in plant genetic resources and traditional knowledge of germplasm within and among plant species represent economic, scientific and societal value which has tendency to solve the food security problems erupt due to expanding global population. An advance made in biotechnology field such as in vitro culture technology, cryopreservation and molecular markers technology has generated significant contributions to improve the methods of conservation of rare and endangered plant genetic resources and traditional knowledge of germplasm and their valuable management in an effective way. A strategic and forward vision for conservation of plant genetic resources and traditional knowledge of germplasm and sustainable use of plant resources in the 21st century is of far reaching significance for sustainable development.

The U.S. Department of Agriculture (USDA), Agricultural Research Service, National Clonal Germplasm Repository in Corvallis was established as the U.S. National Plant Germplasm System's berry genebank in 1981. Since then, the USDA has sponsored numerous explorations throughout the United States and foreign countries to obtain berry plant genetic resources. Species of Fragaria L. (strawberries), Ribes L. (currants and gooseberries), Rubus L. (raspberries and blackberries), and Vaccinium L. (blueberries and cranberries) are native to both domestic and international localities. With limited gene pools for cultivated strawberries, raspberries, and blackberries, expeditions have provided a wealth of genetic resources to expand opportunities for breeders to develop new cultivars. Particularly given the diverse species inherent in the development of cultivated blueberries, these trips have discovered unusual new blueberry relatives and forms available for expanding the range of production, increasing plant yields, and improving fruit antioxidant content. Along the way, new fruit species and new uses for known species were observed. Gathering the bounty of the world's berries resulted in encounters with diverse fauna, from snakes, bears, and bison to butterflies, mosquitoes, ticks, and chiggers. Avenging Toxicodendron species have added their mark on intrepid explorers. Remote sites with nothing but clear night stars and the satellite markers on the global positioning system offer radiant beauty and an abiding hope for the conservation of plant genetic diversity for all people for all time.

Tropical rain forests have long been recognized as a rich repository of plant species, but it is only relatively recently that scientists have understood their crucial role in maintenance of the world's biotic diversity. Ecologists now estimate that the tropical rain forests harbor fully a fourth of the world's species of plantsmore than any other single ecosystem —and it is for this reason that concern is mounting over the recent devastation of tropical forests.

The article covers the issues of plant genetic resources mobilization to the VIR collection from the territories of Pakistan, Bangladesh (until 1947, British India), and Bhutan as a result of collection missions, seed requests, and germplasm exchange. Repeated expeditionary surveys of the territories of modern Pakistan and Bangladesh resumed in the postwar period. In total, from 1971 to 1979 three expeditions were launched: in 1971 and 1978 to Pakistan, and in 1979 to Bangladesh. The first and the only expedition was sent to Bhutan in 1989. As a result, 2911 plant samples were collected and delivered to the Vavilov Institute. Among the collected plant materials, the most numerous were samples of groat crops (885), industrial crops (554), vegetables (517), and cereals (463). In addition to direct collecting, the Institute was constantly ordering plant germplasm through mail requests. There was no inflow of germplasm from Bhutan either in the prewar period or from 1946 to 2019. From Pakistan 338 samples were received, mostly through the USSR Ministry of Agriculture. Only 28 accessions were added to the Institute’s collection from Bangladesh. In total, over the entire period of the Institute’s existence, the total amount of germplasm mobilized from Bangladesh, Pakistan and Bhutan amounted to 3277 accessions, representing 130 plant species. Among them there were many landraces, wild species and crops wild relatives.

The conservation of plant genetic diversity underpins the future of agriculture, food and nutrition security and is critical to ensure the ability of future generations to cope with global environmental changes. The conservation efforts were more focused on orthodox crop species in Nepal before 2010. About 40% of agricultural plant genetic resources are non-orthodox, either recalcitrant/ intermediate type or vegetatively propagated plant species. Approaches for conservation of non-orthodox plant species differ from that of orthodox crops. Different conservation approaches have been established by National Agriculture Genetic Resources Center, Nepal for conserving non-orthodox agricultural plant species. We applied household survey, literatures survey, field survey, key informant survey and organized focus group discussion for assessing the different conservation approaches. A total of 24 approaches are being considered for conservation of non-orthodox plant species. Approaches under the ex-situ strategy are field genebank, botanical garden, city park, government farm, religious place, in-vitro culture and evolutionary plant breeding; under on-farm strategy are community field genebank, school field genebank, household field genebank, community/ public orchard, village level field genebank, geographical indication and participatory landrace enhancement, and under in-situ strategy are protected area, Ramsar site, world heritage site, community forest and legal protection for conserving non-orthodox plant species in Nepal. Field genebank is the very good approach, and it has been established in about 20 research stations. It should be extended to government farms and agriculture offices to conserve the local APGRs available in their respective command areas. Databases (passport and characterization) have been generated and will be available online to enhance the utilization in breeding, research and production.
