Cytoplasmic and Nuclear Effects on Agronomic Traits in Diploid Interspecific Potato Hybrids.

ABSTRACT: The cultivated potato (Solanum tuberosum L.) is a globally important crop with a narrow genetic pool, making it vulnerable to biotic and abiotic stresses. The present study analyzed the relative content of the nuclear, mitochondrial, and plastid genomes and their contributions to agronomic traits in 30 diploid interspecific potato hybrids with diverse cytoplasmic types and pedigrees. The nuclear genome size (2C-value) was estimated using flow cytometry, while the organelle DNA content and cytoplasm types were determined by quantitative polymerase chain reaction (qPCR) and multiplex PCR, respectively. The genome size of individual diploid genotypes remained stable across cultivation conditions, such as in vitro or greenhouse environments. Significant variation was observed in genome
