Abstract: Due to the close genetic base in the papaya crop, the breeding programs seek new alternatives with agronomic characteristics desirable to the producer and fruit that meets the consumer desire. The objective of this work was to evaluate the behavior of new Hybrids in germplasm database maintenance units of the company Caliman Agrícola SA. The experiment was carried out in a randomized block design with 10 new elements (CP3 × SSAM; CP3 × UENF/Caliman 01; CP3 × JS 12; CP2 × SS32; JS 12 × SSAM) and one control, UENF/Caliman 01, four replicates and ten plants per plot. Tem hermaphrodite plants per plot were evaluated at eight and 12 months after planting, 16 characteristics focused on plant morphologies and biometry of fruits harvested at the maturation stage II (fruits with up to 25% of the yellow surface). The productivity of one year of harvest was also evaluated. Among the new hybrids evaluated, it is possible to detect the presence of productive characteristics and fruit quality that were interesting for the market, suggesting that they be evaluated for crop value and use for future launches as commercial hybrids. With interest for future market launch, we highlight CP3 × 72/12, CP2 × SS32, CP3 × Progeny Tainung and CP1 × Sekati which shows high average productivity.
