Description A total of 833 dihaploids tuberized from 31 advanced breeding lines and varieties, recovering 1–106 tubers/genotype from a total of three plants per genotype. We identified 167 dihaploids that showed appealing tubers of more than 2.5 cm. Worth highlighting is the production of 211 dihaploid genotypes from the parental breeding line C93.154 (CIP 392820.1). The line has several attributes such as ER to PVY, resistance to PLRV and LB, high fertile pollen production, and combining ability for yield and tuber quality traits, as well as being progenitor of several breeding clones selected for adaptation to long days and tolerance to heat and drought. This 2x segregating population is suitable for applying modern genetic and genomic tools for discovery and mapping of genes for biotic and abiotic stresses, earliness, and tuber quality and yield.
