Conteúdo: 	In Brazil mainly hermaphrodite plants are exploited for papaya cultivation. Variations of the elongate (normal) hermaphrodite flowers to carpelloid, pentandric and sterile female forms occur in these plants, influenced by genetic as much as by environmental factors. The objective of this study was to estimate these variations of elongate hermaphrodite flowers to deformed and sterile female forms as well as fruit deformations. The results permitted the identification of BC1 plants that were more stable to temperature fluctuations in the winter 2003 and summer 2003/04 in Linhares-ES. For instance, the normal number of hermaphrodite flowers (NHF) varied from 1 to 46 and 0 to 25 in the BC 1 generation, in winter and summer, respectively, while for the 'Golden' genotype these values varied from 7 to 36 in the winter and were zero in the summer as a
result of 100% of flower sterility.
