| An initial evaluation of early selection of physic nut genotypes based on phenotypic data is presented. In order to predict the genetic gains with early selection, genetic parameters, e.g. additive genetic variance, were first obtained for grain yield along with other numerous traits. The results demonstrated that additive genetic variance exists not only for grain yield, which is considered to be the most important trait for oil and biodiesel production, but also for numerous other traits. The predicted genetic gains for grain yield, considering the selection of the 30, 20, 10 and 5 best families in the second crop year are respectively, 40.47, 48.43, 61.78 and 70.28%. With the selection of highly yielding physic nut genotypes indirectly genotypes with... |

| Phenological studies on three morphologically distinct accessions of physic nut (Jatropha curcas L.) were conducted in the Brazilian Savannah biome. Plant growth rate, flowering, fruit formation and development were measured in order to establish appropriate management practices for increasing productivity. The accessions CNPAE-102 (toxic and susceptible to powdery mildew), CNPAE-169 (non-toxic and susceptible to powdery mildew) and CNPAE-259 (toxic and resistant to powdery mildew) were studied. Accessions with undetectable levels of phorbol ester in the grains were considered as non-toxic. The agronomic variables (plant height, number of inflorescences, number of green and ripe fruits per plant) from each accession were measured biweekly during one year... |

| In spite of increasingly widespread interest in planting physic nut, breeding efforts are still in its infancy. In that context, an important resource recently established aiming future breeding efforts was the assembly of a germplasm bank with near 200 accessions. The objective of this study was to estimate genetic parameters, repeatibility coefficients and genetic correlation between seven traits, measured in 110 accessions (half sib families) of this germplasm bank in different stages of development. The results show that higher relative values of additive variance were only found for yield and height, and the existence of low environmental variation (either of temporary or permanent nature) among plots within blocks. Given the high repeatibility values... |

| O objetivo desta pesquisa foi avaliar a qualidade e a vida útil pós-colheita de melancia cv. Crimson Sweet, comercializada em Mossoró, RN. A qualidade dos frutos foi avaliada por local de venda e tamanho de fruto. As melancias de tamanho grande e médio apresentaram melhor aparência externa e maior conteúdo de sólidos solúveis que aquelas de tamanho pequeno, enquanto as comercializadas na ocasião do desembarque apresentaram melhor aparência e maior firmeza. A avaliação da vida útil pós-colheita foi feita com frutos provenientes de um plantio comercial instalado em Mossoró, RN. A perda de peso foi de apenas 3,79%, o pH da polpa aumentou de 4,89 para 5,20, a acidez total titulável decresceu durante o armazenamento e os conteúdos de sólidos solúveis e açúcares... |

| Com o objetivo de identificar genótipos de melão-amarelo, tipo exportação, com alto rendimento, foram avaliados nove genótipos em quatro ambientes no Oeste Potiguar. Os experimentos foram conduzidos no Pólo Agrícola Mossoró-Assu, Estado do Rio Grande do Norte - Brasil. O delineamento experimental foi o de blocos casualizados, com quatro repetições e 16 plantas por parcela. Os genótipos avaliados foram: Rochedo, TSX-32096; PX 4910606, Gold Mine, PX-1010606; Yellow Queen; Gold Pride; Yellow King; AF-646 e AF-682. Os genótipos que apresentaram maior produtividade total, foram Rochedo, TSX-32096, Gold Mine, PX-4010606, Yellow Queen e Gold Pride, com média de 55,1 t/ha, e maior produtividade comercial foram TSX-32096, Rochedo, Gold Mine, PX-4010606 e Gold Pride... |
