SOARES, Edson Basílio et al. Repeatability and correlations among yellow mombim morphoagronomical traits. Ciênc. agrotec. [online]. 2008, vol.32, n.6, pp.1851-1857. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542008000600025.

The objective of this work was to estimate the coefficient of repeatability in fourteen yellow mombim (Spondias mombin L.), in Teresina, Piauí State, through the variance analysis method, in order to determine the number of measures necessary for an accurate prediction of the real genotype value and the correlation coefficients among the leaf length, leaf width, number of leaflets for leaf, panicles weight, number of fruits for panicles, fruit length, fruit diameter, fruit weight, seed weight, pulp revenue, soluble solid (SS), titrable acidity (AT) and SS/AT ratio. The genotypes had significant differences in all traits, indicating the existence of genetic variability. The estimates of the coefficients of repeatability expressed a greater stability for fruit weight, fruit diameter, seed weight, titrable acidity and soluble solid/titrable acidity ratio, indicating more accuracy to the real value pediction of these yellow mombim traits. The evaluation of eleven fruits is enough to predict the real value of all characters with an accuracy of 90%. The selection for characters related to the leaf could lead to an indirect selection for high fruit yield. The high panicle weight could be selected through the indirect selection for low seed weight.
