Genomic heritability estimates in sweet cherry reveal non-additive genetic variance is relevant for industry-prioritized traits

Table 2 Variance components (%), narrow-sense heritability (h²), broad-sense heritability (H²), the coefficient of correlation (r), the coefficient of correlation after cross validation (r_CV), and the total number of observations for model building (N)
