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.
Highlights
The papaya (Carica papaya L.) is one of the most cultivated and consumed fruit trees in the tropical and subtropical regions of the world
The culture is supported by a narrow genetic base where national development and success depends on the emergence of new varieties or hybrids that meets market prospects
The treatments are represented by simple hybrids, being a standard hybrid (UENF/Caliman 01) and 10 new hybrids: CP3 × SSAM; CP3 × UENF/Caliman 01; CP3 × JS 12; CP3 × 72/12; CP3 × Tainung Progeny; CP1 × Sekati; CP1 × Tainung Progeny; CP1 × JS 12; CP2 × SS32; JS 12 × SSAM
Summary
The papaya (Carica papaya L.) is one of the most cultivated and consumed fruit trees in the tropical and subtropical regions of the world. In Brazil, it is the seventh in natura fruit most exported, being cultivated in about 30,445 hectares, which are concentrated in the states of Espírito Santo, Bahia, Ceará and Rio Grande do Norte. The growth of the agribusiness of papaya in Brazil has been favored by a reasonable technological development. The culture is supported by a narrow genetic base where national development and success depends on the emergence of new varieties or hybrids that meets market prospects. The hybrid combinations have been carried out by several authors among the group “Solo” and “Formosa” (Marin, Pereira, Amaral Junior, Martelleto, & Ide, 2006a, 2006b; Ide, Pereira, Viana, & Pereira, 2009; And Boas, 2015; Luz, Pereira, Barros, & Ferreguetti, 2015)
