Authors: L.G. Pinheiro, K.P.T. Chagas, A.S.M. Freire, M.C. Ferreira,C.G. Fajardo and F.A. Vieira
This study uses ISSR molecular markers to characterize the demographic pattern, and spatial genetic structure (SGS) at different life stages of development (cohorts) in a natural population of Copernicia prunifera in the Rio Grande do Norte State, Brazil. All individuals were sampled and georeferenced in a 0.55-ha plot. The de.. Read More»

Genetic diversity of arboreal cotton populations of the Brazilian semiarid: a remnant primary gene pool for cotton cultivars
Authors: I.P.P. de Menezes, L.V. Hoffmann, T.H. de Lima, A.R. da Silva, V.S. Lucena and P.A.V. Barroso
Mocó cotton belong to the same species as the cultivated species, Gossypium hirsutum, and cultivated forms were mainly landraces but also developed as cultivars, bearing good fiber quality and drought tolerant when cropped as a perennial species. The northeast Brazil crop system based on this cotton type is finished, wi.. 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 J�ºnior, 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»

Genetic diversity among 16 genotypes of Coffea arabica in the Brazilian cerrado
Authors: C.M.S. Machado, N.S. Pimentel, A. Golynsk, A. Ferreira, H.D. Vieira and F.L. Partelli
For the selection of coffee plants that have favorable characteristics, it is necessary to evaluate variables related to production. Knowledge of the genetic divergence of arabica coffee is of extreme importance, as this knowledge can be associated with plant breeding programs in order to combine genetic divergence with good p..

Genetic diversity of high performance cultivars of upland and irrigated Brazilian rice.
Authors: G.R.C. Coelho, C. Brondani, L.V. Hoffmann, P.A.M.R. Valdisser, T.C.O. Borba, J.A. Mendon�§a, L.A. Rodrigues and I.P.P. de Menezes
The objective of this study was to analyze the diversity and discrimination of high-performance Brazilian rice cultivars using microsatellite markers. Twenty-nine rice cultivars belonging to EMBRAPA Arroz e Feijão germplasm bank in Brazil were genotyped by 24 SSR markers to establish their structure and genetic discrimi.. Read More»

Periclinal chimera technique: new plant breeding approach
Authors: P.M. Gakpetor, H. Mohammed, D. Moreti and N.M.A. Nassar
Plant interspecific periclinal chimeras are a mosaic formed by tissues from two species. They are manipulated here as an efficient plant breeding tool for cassava root yields. In this study, plants synthesized from two chimeras, designated as chimera 2 and chimera 4, were characterized morphologically and cytologically to unra.. Read More»

Genetic diversity of Plathymenia reticulata Benth. in fragments of Atlantic Forest in southeastern Brazil
Authors: L.C. Souza, A.L. Silva J�ºnior, M.C. Souza, S.H. Kunz and F.D. Miranda
Studies of genetic diversity in natural populations are important for the definition of conservation strategies, especially in populations reduced by processes of fragmentation and continuous forest extraction. Molecular markers stand out as interesting tools for these studies. The objective of this research was to characteriz.. Read More»
