Cape gooseberry (Physalis peruviana) is a climacteric fruit with a fleshy berry type covered by a husk or calyx that prolongs the postharvest shelf life by two thirds more than fruit without husk by decreasing respiratory intensity and reducing weight loss (Bolzan et al., 2011). Such features have resulted in an increasing demand by the consumer market (Santana et al., 2020).
This species belongs to the Solanaceae family. Most of the management (support for the plant, fertilization, weed control, and irrigation) is similar to that used for growing tomatoes (Solanum lycopersicum). The plant is considered shrubby, perennial, and rustic, reaching up to 2 m in height. The leaves are velvety and triangular, whereas the main stem is herbaceous and hairy, and has 8 to 12 nodes. The fruit is fleshy and sphere-shaped, and each plant can produce ≈2 kg of fruit during the entire harvest period (Lima et al., 2009).
Path coefficient analysis or path analysis has been widely used to understand fruit yield better and to determine the nature of the relationships between fruit and their constituent components. This coefficient helps to identify the impacts on fruit mass and can be used as selection criteria. Therefore, path analysis is a multivariate method that can be used to understand and estimate how the correlations of physical variables of fruit affect their mass (Abadi et al., 2021; Oliveira et al., 2021).
We report the results of our study that aimed to select and evaluate correlations between the mass and other physical characteristics of cape gooseberry fruit, indicating direct and indirect effects of the morphology and physical traits on cape gooseberry fruit.
