Genomic constraint and hypervariability correlate with fitness effects in elite tetraploid potato breeding material.

PLoS genetics | 2026-Aug-11

This study investigates genomic constraint and hypervariability in elite tetraploid potato breeding lines using GERP scores to identify sites under selection. It explores the relationship between genetic load and phenotypes, finding that hypervariable sites can improve genomic prediction accuracy for yield, offering insights for molecular breeding strategies in tetraploid potatoes.
