Genetic Diversity Trends in the Cultivated Potato: A Spatiotemporal Overview
15 avril 2022, SPANOGHE, Martin; MARIQUE, Thierry; Nirsha, Alexandra; Esnault, Florence; LANTERBECQ, Déborah, HE CondorcetCARAHArticle scientifiqueRésumé des auteurs : Monitoring the change in genetic diversity over time and space in crop species is essential to facilitating further improvement. As the world’s most important tuber crop for human consumption, and an ideal candidate to help address global food security, the cultivated potato deserves in-depth study in this regard. In this overview, some aspects of spatiotemporal diversity ... -
Genetic patterns recognition in crop species using self-organizing map: the example of the heterozygous autotetraploid potato (Solanum tuberosum L.)
05 février 2020, Spanoghe, Martin; Marique, Thierry; Rivière, John; Moulin, Meganne; Dekuijper, Camille; Nirsha, Alexandra; Bonnave, Maxime; Lanterbecq, Déborah, HE CondorcetCARAHArticle scientifiqueWe tested the ability of the self-organizing map (SOM), a type of artificial neural network, in revealing genetic patterns within the autotetraploid potato (Solanum tuberosum L.). A total of 591 potato varieties, originating from various main European breeder collections and released into different market segments between 1815 and 2015, were examined using a set of 21 informative microsatellite markers. -
Pedigree Validation and Reconstruction Applied in the Cultivated Potato Using 35 Microsatellites Markers
05 juin 2023, SPANOGHE, Martin; Nirsha, Alexandra; MARIQUE, Thierry; LANTERBECQ, Déborah, HE CondorcetCARAHArticle scientifiqueAbstract ; "Knowledge of the parental origin of crop species is a prerequisite for formulating efective strategies for genetic conservation, management, and utilisation of genotypes in breeding programmes and genetic studies. In the case of the potato, although pedigree information is well documented, the possible lack of accurate pedigree data for certain cultivars constitutes a loss of opportunity ...
