1. BEHAVIORAL RESPONSES OF PIGS FINISHED IN DEEP BEDDING AND CONVENTIONAL BED SYSTEMS
ABSTRACT The objective of this study was to characterize the thermal environment and evaluate the behavior of finishing pigs housed in deep bedding and conventional systems. The work was carried out in the Department of Animal Science of the Federal Institute of Education, Science and Technology of Southeast Minas Gerais, Rio Pomba campus. Three pens were us

2. Patterns recognition methods to study genotypic similarity in flood-irrigated rice
ABSTRACT Genetic diversity studies are performed based on information on a set of traits measured in a group of genotypes, considering one or more environments. The pattern recognition methods allow classifying genotypes from a set of important agronomic information. Thus, this study aimed to present and compare pattern recognition methods to inquire about t

5. BRSMG Alterosa: Rice cultivar for lowland cultivation in Minas Gerais
Abstract The lowland rice breeding program, developed in Minas Gerais state, has as basic objective to release new commercial cultivars. In this way, this program is making available a new cultivar named BRSMG Alterosa, which has as main characteristics: high grain yield, high tillering, medium cicle, diseases tolerance and high grain quality. It was recomme

6. Control of plant height by 24 alleles at 12 quantitative trait loci in rice
Abstract Plant height (PH) is controlled by quantitative trait loci (QTLs) in rice. In the present study, a recombinant inbred line population developed by crossing two rice cultivars, Lemont and Yangdao4, was grown in eight environments for QTL analysis. Multiple interval mapping detected 53 PH-QTLs, 39 of which clustered at 12 chromosome regions/putative l

7. New insights into genomic selection through population-based non-parametric prediction methods
ABSTRACT: Genome-wide selection (GWS) is based on a large number of markers widely distributed throughout the genome. Genome-wide selection provides for the estimation of the effect of each molecular marker on the phenotype, thereby allowing for the capture of all genes affecting the quantitative traits of interest. The main statistical tools applied to GWS

8. Combined index of genomic prediction methods applied to productivity
RESUMO: A cultura do arroz tem grande importância nacional e mundial por ser um dos cereais mais produzidos e consumidos no mundo, caracterizando-se como o principal alimento de mais da metade da população mundial. Em função de sua importância alimentar, desenvolver métodos eficientes que visam a predição e a seleção de indivíduos geneticamente

9. Assessment of genetic variation of 15 Thai elite rice cultivars using InDel markers
Abstract Many elite rice varieties have been developed in the last decades by Thai rice breeders. No information about the genetic gene pool of these elite rice varieties is available. This study evaluated the genetic relationship of 15 elite Thai rice cultivars using Indel markers. Of the 133 markers screened, 44 were polymorphic. The PIC scores ranged from

10. Genotypic performance, adaptability and stability in special types of irrigated rice using mixed models
RESUMO É crescente a demanda por tipos especiais de arroz que apresentem, por exemplo, pericarpo preto ou vermelho, baixa amilose (subespécie japonica) ou aromático. No entanto, demandam de intenso processo de melhoramento genético para obtenção e indicação de novas cultivares promissoras geneticamente e adaptadas aos ambientes de cultivo. Neste sent

11. Reaction of lima bean genotypes to Macrophomina phaseolina
RESUMO A podridão cinzenta do caule, causada por Macrophomina phaseolina, é uma importante doença do feijão-fava (Phaseolus lunatus L.) no Nordeste brasileiro. Considerando que no Brasil não existem relatos de resistência a esta doença, 37 acessos de feijão-fava foram avaliados pela reação de resistência e estabilidade da resistência contra isola

12. Self-organizing maps in the study of genetic diversity among irrigated rice genotypes
ABSTRACT. This study presents self-organizing maps (SOM) as an alternative method to evaluate genetic diversity in plant breeding programs. Twenty-five genotypes were evaluated in two environments for 11 phenotypic traits. The genotypes were clustered according to the SOM technique, with variable topology and numbers of neurons. In addition to the SOM analys
