Figure 1
Likelihood ratio test (bar plots) for 13 traits evaluated in 12 'Tahiti' acid lime (Citrus latifolia) genotypes. SDB, stem diameter 5.0 cm above the grafting site; SDA, stem diameter 5.0 cm below the grafting site; SDC, stem diameter at the grafting site; CDL, canopy diameter towards the planting line; CDP, canopy diameter perpendicular to the planting line; PH, plant height; NF, number of fruits per plant; FYP, fruit yield per plant; LFD, longitudinal fruit diameter; EFD, equatorial fruit diameter; ST, shell thickness; TSS, total soluble solids content; and JY, juice yield. All bars above the dashed red line indicate statistical significance, considering the chi-square test, with 1.0 (= 3.84) and 0.5 (= 2.79) degree of freedom (DF), at a 0.05 significance level.

Figure 2
Representation of the principal component analyses and modified Tocher method, showing: the graphical dispersion of the 12 'Tahiti' acid lime (Citrus latifolia) genotypes explained by 86.58% of the variation in a three-dimensional plane with the three main components of the principal component analysis (PCA1, PCA2, and PCA3); and the clusters (clusters 1, 2, and 3) generated by the modified Tocher method using the standardized mean for Euclidean distances. Evaluated genotypes: 1, 'Bello Fruit'; 2, 'Éledio'; 3, 'Iconha'; 4, 'Itarana'; 5, 'Santa Rosa'; 6, 'Bearss Lime'; 7, 'CNPMF 01'; 8, 'CNPMF 02'; 9, 'CNPMF 2001'; 10, 'CNPMF 5059'; 11, 'BRS Passos'; and 12, 'Persian 58'.
