1. Parents choice and genetic divergence between cambuci fruit tree accessions
Abstract Fifty-eight cambuci fruit accessions were collected and propagated by seeds. Forty fruits of each accession were collected and evaluated for longitudinal and transverse diameter, fruit weight, number of seeds, seeds weight, total soluble solids, % citric acid, ratio, pH, firmness, vitamin C, and color. The phenotypic correlation between the characte

2. Relações genéticas entre produtividade de óleo e podridão vermelha das raízes em soja / Genetic relations between oil yield and sudden death syndrome (SDS) in soybean
A demanda por óleos vegetais tem sido crescente, principalmente para utilização como fonte de energia renovável na forma de biodiesel. Somando-se a isso, a podridão vermelha das raízes da soja (PVR), ou síndrome da morte súbita, causada pelo fungo Fusarium solani f.sp. glycines, tornou-se uma doença preocupante para os sojicultores, técnicos e pesq

3. AVALIAÇÃO E SELEÇÃO DE PROGÊNIES DE MEIOS IRMÃOS DE GUARANAZEIRO (Paullinia cupana var. sorbilis (Mart.) Ducke) UTILIZANDO CARACTERES MORFO-AGRONÔMICOS
The aim of this study was to estimate the genetic parameters, variance components, genetic correlations and constructing a selection index of guarana individuals for seed production and a breeding population, among half sib progenies of guarana in Maués, Amazonas, Brazil. Thirty-six progenies were evaluated in a randomized incomplete block design with two r

4. UtilizaÃÃo de tÃcnicas multivariadas e moleculares na caracterizaÃÃo e seleÃÃo de genÃtiopos de feijÃo-caupi de porte ereto e ciclo precoce / use of multivariate techniques and molecular characterization and selection of erect and early cowpea genotypes
Cowpea has great socioeconomic importance in relation to their high contents of protein, drought resistance and good yield. Being cultivated in tropical and subtropical regions of Africa, Brazil and Asia, cowpea is cultivated predominantly by small farmers who use few technological resources. In recent years, cowpea has drawn the attention of medium and larg

5. Evolução do crânio dos macacos do Velho Mundo: uma abordagem de genética quantitativa / Cranial evolution of Old World monkeys and Apes: a quantitative genetics approach
This is a study on the cranial diversification of the Catarrhini, a large group of primates that includes all Old World monkeys and apes, bringing together two approaches to investigate the evolution of complex characters: quantitative genetics and morphological integration. It has three main goals: 1) to compare magnitudes and patterns of inter-trait relati

6. Estratégias para análise do comportamento de genótipos de soja ao nematoide de cistos (Heterodera glycines) / Strategies for analysis the behavior of soybean genotypes to the cyst nematode (Heterodera glycines)
The objectives of this study were the following ones: to evaluate the stability of the soybean cyst nematode race (H. glycines) from the Nematode Bank of the Soybean Breeding Program by the Federal University of Viçosa (NBSBP-FUV), that is kept under greenhouse conditions; to select the soybean genotypes that were originated by one-single pod descending met

7. Resposta fisiológica e anatômica do açaizeiro e da palmeira real australiana ao sombreamento / Physiological and anatomical response of the assai palm and the king palm to the shading levels
The present work involves two species of producing heart of palm: assai palm (Euterpe oleracea) and the king palm (Archontophoenix alexandrae) with objective: to measure the agronomic and physiological characters, in 3 environments of luminosity, to study the anatomy of the palm and to evaluate the behavior of the two species in sight to direct the producer,

8. Avaliação da diversidade genética de populações de fáfia (Pfaffia glomerata (Spreng.) Pedersen) por RAPD, caracteres morfológicos e teor de beta-ecdisona / Genetic diversity of pfaffia populations (Pfaffia glomerata (Spreng.) Pedersen) by RAPD, morphological characters and ß-ecdisone contents
Pfaffia (Pfaffia glomerata (Spreng.) Pedersen) is a native species of South America with widespread occurrence in the States of Paraná, Mato Grosso do Sul and Goiás. Its economic value is mainly due to the similarity of their phytochemical characteristics to the Korean-ginseng (Panax ginseng). Research institutions are carrying out continual germplasm coll

9. Selection and genetic gains for juvenile traits in progenies of Hevea in São Paulo State, Brazil
Five yield traits were investigated in three-year-old progenies from open-pollinated rubber trees [Hevea brasiliensis (Willd. ex Adr. de Juss) Muell.-Arg.]. Twenty progenies were evaluated in a randomized, complete block design replicated three times using 10 plants per linear plot at the North Central Experimental Station in Pindorama, São Paulo State, Bra

10. Heritability of Two Morphological Characters within and among Natural Populations of Drosophila melanogaster
Heritabilities of wing length and abdominal bristle number, as well as genetic correlations between these characters, were determined within and among populations of Drosophila melanogaster in nature. Substantial "natural" heritabilities were found when wild-caught flies from one population were compared to their laboratory-reared offspring. Natural heritabi

11. Effect of Dietary Aflatoxin Concentration on the Assessment of Genetic Variability of Response in a Randombred Population of Chickens
The effect of graded levels of dietary aflatoxin on the assessment of genetic variability of body weight and gain and plasma protein response was tested utilizing the Athens-Canadian randombred population of chickens. Dietary aflatoxin was administered at levels of either 0, 1.25, 2.50 or 5.0 µg/g of diet ad libitum from 7 to 21 days of age to progeny from

12. Quantitative Trait Loci Analysis of Nitrogen Use Efficiency in Arabidopsis
Improving plant nitrogen (N) use efficiency or controlling soil N requires a better knowledge of the regulation of plant N metabolism. This could be achieved using Arabidopsis as a model genetic system, taking advantage of the natural variation available among ecotypes. Here, we describe an extensive study of N metabolism variation in the Bay-0 × Shahdara r
