Authors: Maria Gabriela Fontanetti Rodrigues*, Laís Naiara Honorato Monteiro, Antonio Flávio Arruda Ferreira, Tatiane Paes Dos Santos, Bruno Ettore Pavan, Vitos Antônio Benites Neves, Aparecida Conceição Boliani
Fig is among the twenty main fruits exported by Brazil, which is the eighth largest producer of fig in natura in the world. The characterization of active germplasm banks (AGBs) of fig has thus become an important line of research, as it is necessary to gather information from this to carry out adequate management projects. The objective of this study was.. Read More»

Resistance to Helicoverpa armigera mediated by zingiberene and glandular trichomes in tomatoes for industrial processing
Authors: J.F. Júnior, J.T.V. Resende, A.A. da Silva, A. Gabriel, A.R. Zeist*, R. Favaro, D.A. Nascimento, R.A. Zeist and C.K. Camargo
The Helicoverpa armigera (Hübner) is a recent pest in Brazil, causing losses in tomato production in the Espírito Santo and Goiás states, in Brazil. A promising alternative to control this insect pest is the development of resistent tomato varieties. The breeding programs have aimed to introduce alleles of r.. Read More»

Genetic diversity among accessions of Capsicum annuum L. through morphoagronomic characters
Authors: Angela Maria dos Santos Pessoa, Elizanilda Ramalho do Rêgo, Michelle Gonçalves de Carvalho, Cristine Agrine Pereira dos Santos, Mailson Monteiro do Rêgo
Genetic variability among pepper genotypes is essential in obtaining hybrid combinations with greater heterotic effect and in obtaining superior strains. This work’s goal was to evaluate the genetic diversity between accessions of Capsicum annuum L., indicating the selection of promising individuals for ornamental purpos.. Read More»

Characterization of gametophytic self-incompatibility of superior clones of Coffea canephora
Authors: M.S. Moraes, A.L. Teixeira, A.R. Ramalho, M.C. Espíndula, M.A.G Ferrão and R.B. Rocha
The ability to avoid self-pollination is a trait that evolved as a manner of reducing the deleterious effects of inbreeding in various allogamous plant species, including Coffea canephora. The aim of this study was to perform directed hybridizations to characterize the compatibility groups of superior C. canephora clones, sinc.. Read More»

Contributions of classical and molecular cytogenetic in meiotic analysis and pollen viability for plant breeding
Authors: M.P. Lavinscky, M.M. Souza, G.S. Silva and C.A.F. Melo
The analysis of meiotic behavior has been widely used in the study of plants as they provide relevant information about the viability of a species. Meiosis boasts a host of highly conserved events and changes in genes that control these events will give rise to irregularities that can alter the normal course of meiosis and may.. Read More»

Genetic control of number of flowers and pod set in common bean
Authors: E.S. Martins, R.A. Pinto Júnior, A.F.B. Abreu and M.A.P. Ramalho
This article aimed to study the genetic control of some flowers and pod set of common bean and to verify if its estimate varies with environmental conditions and gene pool. A complete diallel was used among six lines, but no reciprocal ones. The treatments were evaluated in three harvests/generations - F2, F3, and F4 - in 2015.. Read More»
