Genetic Resources: Seeds Conservation
Published in Yeqiao Wang, Landscape and Land Capacity, 2020
Many of the world’s major food plants produce so-called orthodox seeds, which tolerate extensive desiccation and can be stored dry at low temperature. Storage of orthodox seeds is the most widely practiced method of ex situ conservation of plant genetic resources,[1] as 90% of the accessions stored in genebanks are maintained as seed. Following drying to low moisture content (3–7% fresh weight basis, depending on the species), such seeds can be conserved in hermetically sealed containers at low temperature, preferably at –18°C or cooler, for several decades.[1] All relevant techniques are well established, and practical documents covering the main aspects of seed conservation, are available, including design of seed storage facilities for genetic conservation, principles of seed testing for monitoring viability of seed accessions maintained in genebanks, methods for removing dormancy and germinating seeds, and suitable methods for processing and handling seeds in genebanks.[2]

Formed genetic collection—a source of identified genes, genomes and gene complexes genomic complexes, substitution and translocation chromosome aneuploidy, nuclear-cytoplasmic connections, etc. In addition, there is training in gene banks collections for educational programs that covers issues of specific and intraspecific diversity, direction of use, breeding history, genetic diversity on the basic characteristics (reference samples). Gene bank transmits samples users for the implementation of breeding, scientific, educational and other programs. Formation and longterm preservation of basic, attributive, genetic, study collection allows users to stably secure the necessary samples. Exchange of samples of the gene pool of plants is based on the International Agreement on Plant Genetic Resources for Food and Agriculture and bilateral agreements.

The following crop species were used for the experiments. Seeds of common and tartary buckwheat, Fagopyrum esculentum Moench and F. tataricum (L.) Gaertn. (Polygonaceae) were supplied from Institut fir Biologësch Landwirtschaft an Agrarkultur Luxemburg (IBLA). Seeds of maize, Zea mays L. (Poaceae) cv. “Ronaldino”, garden bean, Phaseolus vulgaris L. (Fabaceae) cv. “Neckarkönigin” and quinoa, Chenopodium quinoa Willd. (Chenopodiaceae) cv. “Zeno” stemmed from commercial suppliers. Seeds from the wild plant species were supplied by the Genebank for Wild Plants for Nutrition and Agriculture (Genbank für Wildpflanzen für Landwirtschaft und Ernährung WEL, University of Osnabrück), which has been established for the ex situ conservation of plant genetic resources of Germany. The metal tolerant alpine pennycress, Noccaea caerulescens subsp. calaminaris (syn. Thlaspi calaminaria, Brassicaceae) stemmed from WEL-accession NW-01-0080-2010, while the halophyte annual seablite, Suaeda maritima Durmort (Amaranthaceae), stemmed from the WEL-accession NW-2-236-2012-01.
In vitro investigation of hypoglycemic and oxidative stress properties of fava bean (Vicia faba L.) seed extract in Saccharomyces cerevisiae 2376

Experiments were carried out on seed extracts of fava bean (Vicia faba L.), which were procured from National Bureau of Plant Genetic Resources (NBPGR) New Delhi. It was already authenticated as Vikrant variety. Agroclimatic region of fava bean is found worldwide, mostly in countries such as India (8°4′ to 37°6′ N,68°7′ to 97°25′ E), Pakistan (33°37′N to 73°5′E), China (39°55′N to 116°16′E) and Mediterranean area (30° to 46° N, 6° W to 36° E). Soil type for this crop is red-brown earth, black earth, gray clay, and alluvial loam. Optimal temperature for fava bean growth is 15–20 °C. Mainly this crop is utilized as food material by poor people (rural areas) in India (eastern region).
