Abstract
The use of harmonized microsatellite, and single nucleotide polymorphism, markers through national, European and private projects, and within the European Cooperative Program on Plant Genetic Resources (ECPGR), has allowed numerous international collections of apple and pear germplasm to be molecularly characterized.
We here present the recent developments of assigning a unique genotype code for all accessions sharing the same marker profile. Malus UNiQue genotype codes (MUNQ) have been proposed in Muranty et al. (2020) as an extension of the codes first described in Urrestarazu et al. (2016). A first large data set is publicly available at https://doi.org/doi:10.15454/HKGMAS and regularly updated.
The same coding system is under development for pear with the Pyrus UNiQue genotype codes (PUNQ). MUNQ and PUNQ codes are extremely useful for germplasm managers to compare their own collection with others.
They give information about duplication/redundancy, original uniqueness, or ploidy status and thereby help managers to organize e.g., safety duplication strategies internally and at national/international levels.
MUNQ and PUNQ codes also help in targeting the higher-density genotyping and sequencing effort at the global level.
They allow genotypic data generated in one country to be efficiently used by others.
Limitations and perspectives for such an international apple and pear germplasm coding system will be discussed.
