Fingerprinting of Potato Genotypes from Estonian Genebank Collection Using SSR Markers

Revitalizing agriculture: next-generation genotyping and -omics technologies enabling molecular prediction of resilient traits in the Solanaceae family

“…the Estonian Crop Research Institute has undertaken the fingerprinting of over 450 potato varieties and landraces for the purpose of validating varieties and ascertaining the origin of the material. Employing 8 SSR markers, this endeavor unveiled unique accessions and identified instances of duplicated varieties ( Ivanova-Pozdejeva et al., 2022 ), and the INRAE collection in France sought to develop core collections and facilitate marker-assisted selection, resulting in the fingerprinting of approximately 2,000 accessions using Cleaved Amplified Polymorphic Sequence (CAPS) markers and the SolCAP 8K array. Notably, also the Commonwealth Potato Collection, while only partially genotyped, has been extensively employed in diverse studies encompassing taxonomic and breeding aspects ( Hawkes et al., 1994 ; Bradshaw and Ramsay, 2005 ; Spooner et al., 2005 ), as well as evaluations for resistances and tolerances against both biotic and abiotic stress, exemplified by its assessment for resistance to Potato Virus Y ( Torrance et al., 2020 ).…”

Studies of potato resistance to <i>Globodera rostochiensis</i> revealed novel alleles for 57R marker

“…A selection of these cultivars (including 'Anti' and 'Juku') was also tested for G. rostochiensis resistance in the greenhouse. Additionally, we included 14 potato cultivars of interest to compare with 'Anti' from the data set published by Ivanova-Pozdejeva et al (2021) and a breeding clone from the year 2019. The plant material for 22 Estonian potato cultivars as well as for 14 others was obtained from the in vitro potato collection maintained by the Department of Plant Biotechnology in METK.…”
