1. Correlation and selection gains in F6 wheat genotypes
ABSTRACT The agronomic traits have complex quantitative inheritance, wheat breeding has a highly cost and time expending to achieve advanced lines, and new cultivars. The objective of this work was to estimate the phenotypic (rp), genotypic (rg) and environmental (re) correlation coefficients and the genetic parameters, as well as to estimate the selection g

2. PhenoRoots: an inexpensive non-invasive phenotyping system to assess the variability of the root system architecture
ABSTRACT: The root system architecture (RSA) of plants and its functioning play a fundamental role in a number of plant growth mechanisms including water and nutrient uptake. Optimization of the RSA is important for stable and increased plant productivity under adverse conditions. Despite its great importance, studying the RSA is notoriously laborious becaus

3. Simultaneous selection for yield, adaptability, and genotypic stability in immature cowpea using REML/BLUP
Resumo: O objetivo deste trabalho foi selecionar genótipos de feijão-caupi simultaneamente para alta produção de grãos imaturos, adaptabilidade e estabilidade genotípica, ao se considerar interações genótipos x ambientes. Foram utilizados os modelos mistos máxima verossimilhança restrita (REML)/melhor predição linear não viciada (BLUP). Avaliar

4. Phenotypic correlation of characteristics in the gilt performance test with an average number of live-born piglets through all achieved births, during the reproductive exploitation
RESUMO A eficácia reprodutiva das porcas dita o nível de rentabilidade da própria produção, e o momento do teste e seleção de leitoas para reprodução (como os pais de uma geração futura) representa um momento muito importante. Dado o fato de que a seleção de leitoas para criação é parcialmente baseada no ganho de peso no teste, neste estudo e

5. Growth of radiata pine families in nursery and two years after field establishment
ABSTRACT: Pinus radiata D. Don is the most widely planted exotic species in Australia, Chile, New Zealand and Spain. In this study, growth and survival of P. radiata were compared in 30 open pollinated families grown under two contrasting watering regimes in nursery (well-watered cf. water-stress conditions) and planted on a drought-prone site with Mediterra

6. Bayesian analysis of growth, stem straightness and branching quality in full-sib families of Eucalyptus globulus
ABSTRACT Eucalyptus globulus is one of the most commonly planted hardwood species for industrial use in various temperate regions around the world. The present study aimed to evaluate 62 full-sib families of E. globulus in one of the southernmost progeny trials of the species in the south of Chile. Estimates of genetic parameters for stem straightness, branc

7. Canonical correlation for morphoagronomic and bromatological traits in silage corn genotypes
ABSTRACT The aim of this study is to assess whether there is linear dependence between groups of morphoagronomic and bromatological traits in hybrid silage corn. Nineteen topcross hybrids and five checks were assessed in two different environments in Campos dos Goytacazes and Itaocara counties, Rio de Janeiro State, during the growing seasons 2013/2014. The

8. Media preferences, micro-morphometric analysis, and cardinal growth temperature determination for Phytophthora infestans sensu lato isolated from different hosts in Colombia
Resumo Durante os últimos anos Phytophthora infestans sensu lato causou epidemias na Colômbia em lavouras de frutos andinos, como Solanum quitoense e Solanum betaceum. Estabelecimento de procedimentos experimentais novos ou modificados para estudar este patógeno é um assunto obrigatório para os cientistas. Doze isolados de Phytophthora spp. obtidos de

10. Cardiovascular Disease in Patients with Ankylosing Spondylitis from the Rheumatology Outpatient Clinic of the UFMS-affiliated Hospital
Abstract Background: Cardiovascular diseases are a major cause of morbidity and mortality today. Despite its wide distribution, it presents particularly prevalent in certain groups of individuals, particularly when exposed to a higher degree of inflammation, giving increased cardiovascular risk. Rheumatic diseases expose their holders to this increased card

11. Molecular marker assisted selection for increasing inbreeding in S1 populations of cassava
Abstract The objective of the present work was to use MAS in self-pollinated cassava populations for obtaining individuals with high inbreeding (f) aimed at rapid development of partial inbred lines. Three progenies (F0222, F1378 and F1662) were self-pollinated, generating a total of 233 S1 individuals. The progenies and the S1 individuals were evaluated in

12. Genetic parameters for type score traits and milk production in Brazilian Jersey herds
ABSTRACT This study aimed to estimate the heritability coefficients for ten functional type traits and milk production in the Jersey breed in Brazil, besides the genetic and phenotypic correlations between them. The present study utilised data from 1,567 records of linear type traits, including stature (ST), body depth (BD), loin strength (LS), rump width (R
