Abstract: the objective of this work was to estimate the genetic variability and divergence among 22 superior rubber tree (hevea sp.) genotypes of the iac 400 series. univariate and multivariate analyses were performed using eight quantitative traits (descriptors), including yield. in the univariate analyses, the estimated parameters were: genetic and environmental variances; genetic and environmental coefficients of variation; and the variation index. the mahalanobis generalized distance, the tocher agglomerative method and canonical variables were used for the multivariate analyses. in the univariate analyses, variability was verified among the genotypes for all the variables evaluated. the tocher method grouped the genotypes into 11 clusters of dissimilarity. the first four canonical variables explained 87.93% of the cumulative variation. the highest genetic variability was found in rubber yield-related traits, which contributed the most to the genetic divergence. the most divergent pairs of genotypes are suggested for crossbreeding. the genotypes evaluated are suitable for breeding and may be used to continue the iac rubber tree breeding program.

Abstract: the infant mortality rate (imr) has been determined as one of the most important health indicators by the alma-ata conference of the world health organization that also recognized primary health care as the key for health promotion. the united nations international childhood fund and the pan-american health organization devised low cost strategies for poor countries to reduce infant mortality rates such as growth monitoring, oral rehydration, breastfeeding, and vaccination. the assumption that substantial imr reduction is related to quality of life improvement has been questioned due to specific interventions of the health sector. in this scenario ceará and a large part of the northeast has historically coped with adversities in the social, economic and demographic areas including health care, thus establishing a causal relation among these sectors especially concerning infant mortality. macroepidemiological determinants for infant survival would be out of the health sector capacity of intervening therefore, only significant change of economic standards or social policies intensification, assuring continuity of education issues, of sanitation and generation of employment and income could have an impact on the population health and consequently on infant mortality. such hypothesis justifies a more in-depth investigation under a methodological viewpoint.

Abstract: the geographic distribution of health problems and its relationship to potential risk factors has opened a vast field for epidemiological research. the present study aims to identify spatial distribution patterns for the neonatal and post-neonatal components of the infant mortality rate (imr) in ceará state, brazil, and discuss the main socioeconomic, demographic, and healthcare factors contributing to the spatial dependence of these components. this cross-sectional ecological study uses multiple linear regression, in which spatial analysis of the components was obtained through the moran index. prenatal, childbirth, and neonatal care as well as improved income distribution are decisive for survival in the first month of life, while other factors related to nutrition, immunization, sanitation, education, and economic status are possible determinants of post-neonatal mortality. selective healthcare measures are known to play a decisive role in decreasing the imr. however, structural and inter-sector changes generate the sustainability needed to maintain this indicator on the same level as in developed countries.

Abstract: objective: to assess ecological models to describe infant mortality rate in ceara (northeastern brazil) in two different periods of time. methods: this was a cross-sectional ecologic study of two years, 1991 and 2000, using non-matching information per municipalities. estimates on the infant mortality rate of the instituto de pesquisas econ?micas aplicadas (institute of applied economic research) have been used. for the remaining indicators different sources of the system of health information were used. the main risk factors were assessed using multiple linear regression. results: in 1991, the variables that predicted infant mortality rate (r2=0.3575) were: small houses (b=0.0043; r=0.010), proportion of inhabitants with tap water in the household (b=-0.0029; r=0.024), urbanization rate (b=0.0032; r=0.004), fecundity rate (b=0.0351; r=0.024), the proportion of children working at 10-14 years (b=0.0049; r=0.017), proportion of families with income < ? minimum wage (b=0.0056; r=0.000), that can read and write (b=-0.0062; r=0.031). in the year 2000, the following possible determinants were identified (r2=0.3236): the proportion of children <2 years of age with malnutrition (b=0.0064; r=0.024), proportion of households with adequate sanitation (b=-0.0024; r=0.010), proportion of women who could read and write (b=-0.0068; r=0.044), expenses on health human resources regarding total health expenses (b=-0.0024; r=0.027), proportion of the value of the vegetal production in relation to the total of the state (b=-0.1090; r=0.001), intensity of poverty (b=0.0065; r=0.002), and ageing index (b=-0.0100; r=0.006). conclusions: although the variables have not been exactly the same for the evaluated period, determiners of infant mortality have been changing, except for indicators of education, income and sanitation. the overall decrease in fecundity led to a reduction in its discriminating power, and it was replaced by the ageing index. another tendency observed was the replace o

Abstract: genetic diversity of 60 hevea genotypes, consisting of asiatic, amazonian, african and iac clones, and pertaining to the genetic breeding program of the agronomic institute (iac), brazil, was estimated. analyses were based on phenotypic multivariate parameters and microsatellites. five agronomic descriptors were employed in multivariate procedures, such as standard euclidian distance, tocher clustering and principal component analysis. genetic variability among the genotypes was estimated with 68 selected polymorphic ssrs, by way of modified rogers genetic distance and upgma clustering. structure software in a bayesian approach was used in discriminating among groups. genetic diversity was estimated through nei's statistics. the genotypes were clustered into 12 groups according to the tocher method, while the molecular analysis identified six groups. in the phenotypic and microsatellite analyses, the amazonian and iac genotypes were distributed in several groups, whereas the asiatic were in only a few. observed heterozygosity ranged from 0.05 to 0.96. both high total diversity (ht' = 0.58) and high gene differentiation (gst' = 0.61) were observed, and indicated high genetic variation among the 60 genotypes, which may be useful for breeding programs. the analyzed agronomic parameters and ssrs markers were effective in assessing genetic diversity among hevea genotypes, besides proving to be useful for characterizing genetic variability.

Abstract: the objective of this work was to assess, during six years, the temporal stability of natural rubber yield of 25 superior hevea brasiliensis genotypes, using the wricke, eberhart & russell, lin & binns, additive main effect and multiplicative interaction (ammi) analysis, and harmonic mean of the relative performance of the genetic values (hmrpgv) methods. the iac 40 and iac 300 genotypes were identified as stable and high yielding by the eberhart & russell, lin & binns, hmrpgv, and ammi biplot methods. the ranking of the other more stable genotypes identified by these analyses was altered. the observed results in the ammi biplot agreed with those observed in the wricke method for identifying stable, but lower yielding genotypes. the simultaneous use of different methods allows a more accurate indication of stable genotypes. stability analyses based on different principles show agreement in indicating stable genotypes.
