| Resumo: | The melon (Cucumis melo L.), belongs to the genus Cucumis of the family Cucurbitaceae, is an appreciated oleracea worldwide and is one of the most exported. The Brazilian Northeast is responsible for more than 95% of the production and export of domestic melon (Cucumis melo L.). The prominent position of this region is due to the prevailing edaphoclimatic conditions for the cultivation of melon and the use of high production technology by the productive sector. The present work aimed to evaluate eight Cantaloupe melon hybrids in the state of Rio Grande do Norte. The experimental trials were conducted in the municipalities of Mossoró and Baraúna, belonging to the Agropolo Mossoró-Assú
Adaptability and stability studies of predicted genotypic values were performed by the MHPRVG procedure (Harmonic Mean Relative Performance of Genetic Values). Seven experimental hybrids (CA-01, CA-02, CA-03, CA-04, CA-05, CA-06 and CA-07) and the control hybrid Torreon (Syngenta®) were evaluated. The evaluated characters were the productivity and the soluble solids content. Genotype x environment interaction was verified for both variables. There was a predominance of the complex part of the interaction for the two characteristics evaluated, hindering the selection process. Regarding the MHVG (Harmonic Mean Genotypic Values) parameter, the highest estimate for yield was observed for genotype CA-05 followed by genotypes CA-02 and CA-03. For soluble solids, CA-05 also stood out with the highest estimate while the lowest estimate was observed in the 'Torreon' hybrid. It was found that the CA-05 hybrid with higher estimates stood out from the others as the most promising for cultivation in Agropolo Mossoró-Assú because it has high stability, adaptability and high productivity. |
