“…This is common practice with wild potato germplasm, and accessions are maintained as botanical seeds or true-potato seeds (TPS). A representative number of 20–50 individuals are typically collected from a wild population, and seeds are regenerated and combined to form a unique genebank accession of heterogeneous seed, which is expected to represent most alleles found in that population [ 85 ]. Seed samples of such wild potato germplasm accessions thus represent a heterogenous mix of genotypes, whereby each genotype represents a portion of the genetic make-up of the sampled population.…”

The history of ex situ conservation is relatively short, not more than a century old. During the middle of last century, triggered by the realization that genetic erosion was threatening the existing landraces and wild relatives of the major food crops, global efforts to collect and conserve the genetic diversity of these threatened resources were initiated, predominantly orchestrated by FAO. National and international genebanks were established to store and maintain germplasm materials, conservation methodologies were created, standards developed, and coordinating efforts were put in place to ensure effective and efficient approaches and collaboration. In the spontaneously developing global conservation system, plant breeders played an important role, aiming at the availability of genetic diversity in their breeding work. Furthermore, long-term conservation and the safety of the collected materials were the other two overriding criteria that led to the emerging international network of ex situ base collections. The political framework for the conservation of plant genetic resources finds its roots in the International Undertaking of the FAO and became ‘turbulent rapid’ with the conclusion of the Convention on Biological Diversity. This paper reviews the history of the global ex situ conservation system with a focus on the international network of base collections. It assesses the major ex situ conservation approaches and methods with their strengths and weaknesses with respect to the global conservation system and highlights the importance of combining in situ and ex situ conservation.

“…Plant germplasm collection and its conservation are an integral part of safeguarding the availability of plant genetic martials for present and future breeding programs of imperative horticultural and agricultural plant crops; preservation of rare and endangered species, and of heritage plants (Johnson, 2002). Potato genetic resources held ex situ are divided in to potato wild relatives (maintained as seed populations) and cultivated varieties which are maintain either in field plantings (where tubers are planted and harvested annually, seed, in vitro/clonal material, or cryopreserved material (Ellis et al, 2020). The method of ex situ conservation of potato germplasm as seed (tubers) is not only labor intensive, time-consuming, cumbersome but also the conserved materials would be lost due to exposure to hazards, pest, diseases and other natural catastrophes.…”

No cell or tissue culture problem is as universal as that of culture loss due to contamination, so that microbial hazards cause drastic economic losses in the plant tissue culture industries. A wide range of microorganisms (filamentous fungi, yeasts, bacteria, virus and viroid) and micro-arthropods (mites and thrips) have been identified as contaminants in plant tissue culture. With this paramount importance of in-vitro culture contaminants, various research work has been conducted from different corners of the world. This review paper compiles such important information to share experiences within a single amassed document. Different research and review articles, proceedings, protocol notes, scientific notes, conference papers, case reports as well as case studies, research communications and technical reports are included in this paper. Hence, this article aimed to review and provide insights about microbial contaminants and their management techniques and thereby to document the possible attempts made by different scholars to mitigate microbial contamination under plant tissue culture. Moreover, the paper skim through the current advancements made on culture loss due to microbes, their control methods and hostile effects on regeneration capability of culture plants.

The diversity of potato genetic resources in the VIR genebank harbors one of the world’s first collections of primitive cultivated species. These accessions are native potato varieties cultivated by the indigenous population of South America. The oldest accessions in the collection are traced back to 1927. Approximately one fifth of the collection (106 accessions out of 573) is the unique material procured by VIR’s collecting missions to Bolivia, Colombia, Ecuador, and Peru. According to S. Bukasov’s potato classification, the diversity of South American highland potatoes explored by VIR’s collectors belongs to spp. Solanum ajanhuiri Juz. et Buk., S. × chaucha Juz. et Buk., S. mammilliferum Juz. et Buk., S. phureja Juz. et Buk., S. rybinii Juz. et Buk., S. goniocalyx Juz. et Buk., S. stenotomum Juz. et Buk., S. tenuifilamentum Juz. et Buk., S.× juzepczukii Buk., and S. × curtilobum Juz. et Buk. Within this group of species, S. × ajanhuiri, S. phureja and S. stenostomum are the closest in their characteristics to ancient domesticated forms of tuber-bearing Solanum spp. This publication is an analytical review of the current composition of the primitive cultivated potato species collection and the results of its earlier studies. Ecogeographic descriptions of the sites native for cultivated potatoes and information on the sources of the accessions are presented. A large-scale evaluation of primitive cultivated potato accessions by a set of characters, carried out in field and laboratory experiments, uncovers their breeding potential and serves as the primary information platform for further indepth research. Studying S. phureja and closely related cultivated potato species is important for finding solutions of fundamental problems in plant biology. The data arrays accumulated today would facilitate targeted selection among accessions to identify most promising ones for molecular genetic studies into the gene pool diversity of potato species.
