Genetic diversity analyses of tropical goats from some countries of Middle East
Authors: R.M. Al-Atiyat
The genetic structure of 10 goat breeds from four countries of the Middle East and Horn of Africa was investigated at 17 microsatellite loci. The average allele number and richness were 9.65 and 5.78, respectively. The mean expected heterozygosity per population was 0.703, 0.715, 0.719, 0.699, 0.749, 0.719, 0.731, 0.721, 0.719.. Read More»

Authors: D.R. Queiroz, F.J.C. Farias, J.J.C. Vasconcelos, L.P. Carvalho, D.G. Neder, L.S.S. Souza, F.C. Farias and P.E. Teodoro
This study aimed to estimate the general- (GCA) and specific-combining ability (SCA) and obtain information on the genetic control of agronomic traits among six upland cotton genotypes and their hybrid combinations. In 2015, six cotton genotypes (FM 993, CNPA 04-2080, PSC 355, TAM B 139-17, IAC 26, and TAMCOT-CAMD-E), and fift.. Read More»

Efficiency of selection per se and in single-cross hybrids for disease resistance in maize
Authors: R.B. Camargos, R.G. Von Pinho, M. Balestre, R.A.D.C. Ferreira, K.O.G. Dias, L.P.M. Pires and V.F. Souza
Plant breeding strategies are constantly refined to increase efficiency during the selection process. Consequently, the aims of this study were to examine genetic control and efficiency of selection based on the per se performance of maize lines and based on hybrid performance in reaction to white spot, common rust, and ear ro..

Investigation on possible occurrence of somaclonal effects in zygotic and embryonic cotton structures based on agronomical traits
Authors: T.C. Soares, J.M.F.C. Carvalho, L.M. Lima, R.M.M. Freire,C.R.C. Silva, P.A. Melo Filho and R.C. Santos
Zygotic and embryonic cotton structures were used in in vitro procedures to obtain stable plants. Zygotes (24, 48, and 72 h) and immature embryos (10 and 25 days after fertilization) were grown in MS medium supplemented with glucose, indoleacetic acid, kinetin, and activated charcoal. Regenerated seedlings were acclimatized an.. Read More»

Soybean genotype analysis for cyst nematode resistance
Authors: B.C.M. Juliatti, I.F. Beloti, L.C. Pena and F.C. Juliatti
Some species of soybean cultivars have the characteristic of resistance or alteration in survival skills, and perpetuation of nematodes (female index - FI), whose process is activated when the nematode parasitism starts and the development of new resistant cultivars is primordial to the preservation of plant productivity. The .. Read More»

Farmer variety exchange along Amazonian rivers influences the genetic structure of manioc maintained in a regional Brazilian Gene Bank
Authors: S.B. Sousa, G.F. Silva, M.C. Dias, C.R. Clement and N.R. Sousa
Knowledge of agro-morphological and genetic variability of germplasm diversity is a prerequisite for its use in breeding. The aim of this study was to characterize the genetic diversity of the manioc (Manihot esculenta) Active Germplasm Bank (AGB) at Embrapa Amazônia Ocidental using microsatellite markers. We evaluated 4.. Read More»

Diversity and genetic structure of the native Brazil nut tree (Bertholletia excelsa Bonpl.) population
Authors: J.C. Cabral, A.B. Baldoni, H. Tonini, V.C.R. Azevedo, L.D. Giustina, A.V. Tiago and A.A.B. Rossi
The present study was carried out in a native Brazil nut tree population (Bertholletia excelsa Bonpl., Lecythidaceae) to assess its genetic diversity and structure. Ten microsatellite markers were used to genotype 198 adult trees (B. excelsa). The population presented high genetic diversity and inbreeding absence rates. The em.. Read More»

Bayesian analyses of genetic parameters for growth traits in Nellore cattle raised on pasture
Authors: F.B. Lopes, J.L. Ferreira, R.B. Lobo and G.J.M. Rosa
This study was carried out to investigate (co)variance components and genetic parameters for growth traits in beef cattle using a multi-trait model by Bayesian methods. Genetic and residual (co)variances and parameters were estimated for weights at standard ages of 120 (W120), 210 (W210), 365 (W365), and 450 days (W450), and f.. Read More»

Selection of maize inbred lines and gene expression for resistance to ear rot
Authors: G.S. Pereira, R.G.V. Pinho, E.V.R.V. Pinho, L.P.M. Pires, L.A.Y. Bernardo Junior, J.L.A. Pereira and M.P. Melo
In recent years, there has been a large incidence of fungi causing “ear rot” in maize in Brazil, the main fungus being Fusarium verticillioides. The most efficient and competitive alternative for control of this disease consists of using maize hybrids resistant to this pathogen. Thus, the aims of this study were to.. Read More»
