The results of ANOVA and those associated with genetic parameters indicate the existence of variability in the genotypes under assessment. A greater influence of genetic factors was observed in the expression of characteristics associated with the evaluated variables, except for the soluble solids content and the titratable acidity. Heritability values were high, varying between 67.9% for titratable acidity and 96.1% for the proportion of ?-carotene in relation to the total carotenoids content. Principal Component Analysis (PCA) evidenced four divergent groups of genotypes for the characteristics assessed. The results indicate a favorable situation for selection and promising advances in the next stages of the breeding program, aiming to obtain elite lines.  aCarotenoids  aGenetic variance  aGenotype  aPumpkins  aAbóbora  aCarotenóide  aCucúrbita Moschata  aGenótipo  aMelhoramento Genético Vegetal  aVariância fenotípica  aVariância genética1 aLIMA, M.
