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»

Morphological, cytogenetic, and molecular characterization of Arachis kuhlmannii Krapov. & W.C. Greg. (Leguminosae)
Authors: A.P. F�¡vero, A.P.S. Pe�±aloza, C.R. Lopes and J.F.M. Valls
Arachis kuhlmannii occurs in Mato Grosso and Mato Grosso do Sul States, Brazil. Its area of occurrence partially overlaps with that of other species in the Arachis section. Because of their morphological similarities, these species are often mistaken one for another. This study aimed the correct classification of available acc.. Read More»

Variability among Capsicum baccatum accessions from Goi�¡s, Brazil, assessed by morphological traits and molecular markers
Authors: A.L.A. Martinez, J.S.P. Ara�ºjo, C.F. Ragassi, G.S.C. Buso and F.J.B. Reifschneider
Capsicum peppers are native to the Americas, with Brazil being a significant diversity center. Capsicum baccatum accessions at Instituto Federal (IF) Goiano represent a portion of the species genetic resources from central Brazil. We aimed to characterize a C. baccatum working collection comprising 27 accessions and 3 commerci.. Read More»

Genetic identification of Theobroma cacao L. trees with high Criollo ancestry in Soconusco, Chiapas, Mexico
Authors: J.A. V�¡zquez-Ovando1,4, F. Molina-Freaner2, J. Nu�±ez-Farf�¡n3, I. Ovando-Medina4 and M. Salvador-Figueroa4
Criollo-type cacao trees are an important pool of genes with potential to be used in cacao breeding and selection programs. For that reason, we assessed the diversity and population structure of Criollo-type trees (108 cultivars with Criollo phenotypic characteristics and 10 Criollo references) using 12 simple sequence repeat (SSR) markers. Cultivars were.. Read More»

Authors: B.A. Crispim1, A.B. Grisolia1, L.O. Seno2, A.A. Egito3, F.M. Vargas Junior2 and M.R. Souza2
Sheep of the Pantaneiro breed and seven other breeds, raised in the State of Mato Grosso do Sul, Brazil, were genotyped using eight microsatellite loci. The aim of the present study was to determine the genetic variability, phylogenetic relationship, and patterns of gene introgression and miscegenation among the animals surveyed, to obtain information abo..

Use of morpho-agronomic traits and DNA profiling for classification of genetic diversity in papaya
Authors: O.N. de Jesus, J.P.X. de Freitas, J.L.L. Dantas and E.J. de Oliveira
We examined the genetic diversity of papaya (Carica papaya) based on morpho-agronomic and molecular data. Twenty-seven genotypes grown in Brazil were analyzed with 11 AFLP primer combinations, 23 ISSR markers, 22 qualitative, and 30 quantitative descriptors. For the joint analyses, we used the Gower algorithm (Joint Gower) and the average value of the ind.. Read More»
