| Poucas cultivares de coentro (Coriandrum sativum L.) estão disponíveis aos produtores e, em algumas regiões, cultivam-se genótipos de origem desconhecida, mantidos pelos próprios hortelãos. Para conservar as cultivares tradicionais é necessário não só coletá-las e conservá-las, mas também caracterizá-las. Dessa forma, este trabalho teve por objetivo determinar caracteres morfológicos para diferenciar genótipos de coentro no processo de registro de cultivares. Foram realizados dois experimentos, ambos em blocos casualizados, com cinco repetições. As cultivares Americano, Asteca, Palmeira, Português, Santo, Supéria, Tabocas, Tapacurá e Verdão, além da linhagem HTV-9299 foram analisadas para caracteres de fruto, plântula, folhas, folíolos e flores. Os dados... |

| Grande número de produtores envolve-se com o cultivo do coentro durante todo o ano, tornando a cultura importante social e economicamente. Praticamente em toda a região Nordeste utiliza-se a cultivar Verdão. Estudos da variabilidade genética do coentro são importantes, tendo em vista o melhor planejamento de programas de melhoramento genético. Desta forma, este trabalho teve como objetivo quantificar a variabilidade genética de características agronômicas do coentro cultivar Verdão, avaliando-se progênies de meios-irmãos potencialmente úteis no melhoramento genético. O trabalho foi desenvolvido na Universidade Federal Rural de Pernambuco, em casa de vegetação, em blocos casualizados, com cinco repetições e parcelas de 28 plantas, colocadas em dois vasos.... |

| With the development of new cultivars, a precise genetic characterization is essential for improvement programs or for cultivar registration and protection. Molecular markers have been complementing the traditional morphological and agronomic characterization techniques because they are virtually unlimited, cover the whole genome and are not environmentally influenced. Genetic characterization constitutes the basis for studies involving estimates of genetic similarity. Therefore, the objective of the present study was to evaluate the genetic similarity between ten coriander genotypes (nine cultivars and one line) using ISSR markers. The cultivars used were: Americano, Asteca, Palmeira, Português, Santo, Supéria, Tabocas, Tapacurá, Verdão and the... |

| ABSTRACT The aim of this study was to estimate the genetic divergence among eggplant genotypes for agronomic traits in order to gather information for the selection of genotypes in eggplant breeding programs for tolerance to high temperatures. Ten traits recommended by the International Board for Plant Genetic Resources were analyzed in 24 genotypes, arranged in a randomized complete block design with four replicates. Data were submitted to analysis of variance (P<0.01) and later to the UPGMA and Tocher grouping methods, using the generalized Mahalanobis distance (D2) as dissimilarity measure. Three and six groups of similarity were obtained, respectively, for the multivariate techniques used, UPGMA and Tocher, with concordance in the grouping of 87.50%... |

| In Brazil, the cowpea [Vigna unguiculata (L.) Walp], is important in the Northeast Region, where it is typically grown on family farms. The importance of the damage caused to the seed quality of this species by stored pests has been described in various studies. Using X-ray, it is possible to see the internal seed structures and identify possible changes and damage. The objective of this study was to identify the damage caused by the weevil [Callosobruchus maculatus (Fabr.)] by analyzing X-ray and evaluate its relationship to the physiological quality of the cowpea seed. Three cultivars were used (IPA-206, BRS-Pajeu and BRS-Potengi) and two lines (L 281.005 and L ESP 10). The samples were exposed to X-ray and germination test to determine the cause-effect... |

| ABSTRACT The objective of this work was to estimate the combinatorial capacity and heterosis of eggplant hybrids under high temperature conditions. Seven genitors, twelve hybrid combinations, originated from a partial diallel, and the Ciça F1 hybrid, as control, were evaluated. The experiment was conducted under greenhouse conditions in randomized block design with four replications, from April to December 2017. The assessed traits related to high temperatures were pollen viability (PV) and fruit fixation index (FFI); the morphoagronomic traits were number of fruits per plant (NFP), fruit weight (FWe), production per plant (PP), fruit length (FL), fruit width (FWi), fruit length/width ratio (FLWR) and plant height (PH). The variance analysis showed... |
