1. ACCURACY OF GENETIC PARAMETERS ESTIMATION AND PREDICTION OF GENOTYPIC VALUES IN EUCALYPTUS USING DIFFERENT PLOT TYPES
ABSTRACT A suitable experimental design should control the environmental effect and be capable of discriminating genotypes. Two clonal tests of Eucalyptus were planted side by side in a randomized block design with the same 32 treatments under two different plot designs. The first trial was designed with five plants per plot (linear plot, LP) and six block r

3. Genetic parameters and agronomic characterization of elite barley accessions under irrigation in the Cerrado
ABSTRACT. There is a demand for barley cultivars that are suitable for the malt industry as well as genotypes that are stable and better adapted for irrigation in the Cerrado. This study aimed to estimate the genetic parameters by assessing 69 barley genotypes from different countries, from 2012 to 2014, under irrigation in the Cerrado. Six agronomic charact

4. Correlations between agronomic traits and path analysis for silage production in maize hybrids
ABSTRACT The aim of the current study is to estimate the correlation coefficients and the consequence of genotypic correlations on direct and indirect effects through path analysis between agronomic traits of maize hybrids used for silage production. Eight (8) topcross hybrids and seven (7) checks were analyzed in completely randomized blocks, with six repli

5. Genetic parameters estimates and visual selection for leaves production in Ilex paraguariensis
ABSTRACT The selection of yerba mate superior genotypes, based on each plant leaf weight, is based on genetic parameters obtained from experimental plantations and it is practically impossible from the fourth year of age. Therefore, we estimate genetic parameters and check the feasibility of selection through notes and weight estimates of each tree at 18.5 y

6. Bayesian estimation of genotypic and phenotypic correlations from crop variety trials
Abstract Genotypic and phenotypic correlations are necessary for constructing indirect selection indices. Bayesian analysis, therefore, was applied to obtain posterior distributions of the correlations, and the estimates were compared with those under a frequentist approach. Three a priori distributions for standard deviation components based on uniform dist

7. Hepatitis B virus genotyping in chronic hepatitis B patients in southwestern Saudi Arabia
ABSTRACTThe distribution of hepatitis B virus genotypes in Saudi Arabia is largely unknown. To the best of our knowledge there are no data available about HBV genotypes in southwestern region of the country. This study aimed to determine the epidemiologic distribution of hepatitis B virus genotypes in chronic hepatitis B patients in southwestern region, and

8. Molecular analysis of holoprosencephaly in South America
Holoprosencephaly (HPE) is a spectrum of brain and facial malformations primarily reflecting genetic factors, such as chromosomal abnormalities and gene mutations. Here, we present a clinical and molecular analysis of 195 probands with HPE or microforms; approximately 72% of the patients were derived from the Latin American Collaborative Study of Congenital

9. Desempenho de 79 progênies de soja na geração F6 e correlações fenotípicas, genotípicas e ambientais / Performance of 79 soybean progeny of F6 generation and their phenotypic, genotypic and environmental correlations
Soybean farmers have interest on increasingly early highly productive cultivars has stimulated the development of new genotypes for breeding soy programs. So that, this study aimed to evaluate the agronomic characteristics of 79 progenies of ten biparental crosses Program Soybean Breeding in Federal University of Uberlândia. The experiment was conducted at

10. Relationship between grain colour and preharvest sprouting-resistance in wheat.
Since red alleles (R) of the genes that control grain colour are important for the improvement of preharvest sprouting resistance in wheat and there are three independently inherited loci, on chromosomes 3A, 3B and 3D of hexaploid wheat, it is possible to vary the dosage of dominant alleles in a breeding program. The objective of this work was to evaluate th

Um modelo de matriz energética mundial, idealmente baseado em fontes mais limpas e renováveis de energia em relação ao petróleo, se justifica pela crescente preocupação com a questão do aquecimento global. Além disso, pesquisas em biocombustíveis como fontes alternativas de energia são essenciais para garantir a atual posição de autonomia energ�
