, 2018 ). Breeding new macadamia varieties is usually focused on harnessing higher nut yield per tree. However, selecting for yield is challenging due to the polygenic nature of the trait, low heritability ( H ≈ 0.12), and large genotype by environment

on environmental conditions such as location, year, tree, and fruit, and therefore its broad-sense heritability and environmental variances have to be estimated for efficient breeding ( Nyquist, 1991 ; Yamada et al., 1993 , 1994 ). Accordingly, the

. The phenotypic variance between trees of the same genotype provided an estimate of the environmental variance (V E ). Broad-sense heritabilities (H) were estimated by subtraction of V E from the total phenotypic variance taken across all trees (V P

. The use of a set of hybrids and their respective parents also allowed us to obtain information on the heritability of phenolic concentration and browning-related traits in eggplant. This is of interest for breeding new eggplant varieties that combine

extremely little documentation of ploidy for specific cultivars and clones. Minimal work has been published on genetics and heritability of specific traits in aucuba. Hagedoorn (1950) first reported that the spotted leaf trait was maternally inherited and
