This article provides a theoretical review of the fundamentals and estimation of heritability and its practical applications in plant breeding programs. Heritability is an essential genetic parameter for selection, reflecting the heritable portion of phenotypic variance. Thus, its fundamentals and estimates are presented, indicating its application in plant breeding. Population structure, evaluation methods, and experimental design are important factors in heritability estimation; with low genetic variability, average heritabilities are more robust. Strategies based on repeated measurements and repeatability contribute to increasing selection efficiency. The choice of the selection unit and the estimation method should consider the breeding objectives, the genotype × environment interaction, and the reproductive systems of the species.
