Abstract
To identify promising genotypes for commercial cultivations and studies of genetic improvement with sugar apple, eight fruits each of 30 genotypes of the species were charactyerized by: length and fruit diameter, fruit mass, pulp mass, seed mass, rind mass and receptacle mass, pulp yield, number of seeds, thickness of the rind, pH, total soluble solids (TSS), total titratable acidity (TTA), vitamin C, TSS/TTA ratio, moisture, ash content, total, reducing and non-reducing sugars. Results were evaluated by descriptive statistics (mean, standard deviations and coefficient of variation) and statistical multivariate analysis, by grouping techniques and main component analysis. The genotypes were clustered in 10 gentically divergent groups, which allowed the selection of promising genotypes. The highly variable traits fruit, pulp, and rind mass and number of seeds contribute to the differentiation of the evaluated genotypes
