1. Genetic divergence and combined selection for traits that provide high agronomic performance in common bean lines
ABSTRACT The selection of common bean lines with intermediate cycle, upright plant architecture and high grain yield is an important goal of breeding programs. This study proposes to examine the genetic diversity of common bean genotypes for agronomic traits, select superior genotypes for traits that provide high agronomic performance and define promising cr

2. Genotype by environment interaction and adaptability of photoperiod-sensitive biomass sorghum hybrids
ABSTRACT Biomass sorghum is an alternative feedstock to cogenerate energy and produce second-generation ethanol. The aim of this study was to evaluate the Genotype by Environment Interaction (GEI) in biomass sorghum and to identify the hybrids that associate high adaptability and stability using the Toler nonlinear regression, the Genotypes plus Genotype by

3. Timing and growing conditions of nitrogen topdressing influence the grain yield and protein content of four wheat cultivars
ABSTRACT The application of an adequate rate and splitting of nitrogen is essential for wheat grain yield and protein content. The aim of this work was to adjust nitrogen management approaches regarding agronomic performance and protein content of wheat cultivars in various environments. Field experiments were conducted under no-tillage system on soybean mul

4. EFFECTS OF COMPETITION AND WATER DEFICIENCY ON SUNFLOWER AND WEED GROWTH
RESUMO No ambiente agrícola é comum a ocorrência de estresse de origem biótica e abiótica, como a interferência das plantas daninhas e o déficit hídrico no solo, respectivamente. Porém, pouco se conhece sobre os efeitos da interação desses estresses sobre o crescimento de espécies cultivadas e daninhas. Desta maneira, objetivou-se com este trabal

5. Procedures for identification of superior progenies in successive generations of evaluation in common bean
ABSTRACT: When breeding the common bean in Brazil, the best progenies are chosen, normally, from solely the generation under analysis at the conclusion of the evaluation, without considering what occurred in the past. However, a number of recently published studies show that if an evaluation were to consider all relevant generations, the gain from selection

6. 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

7. Number of stems and plant density in mini watermelon grown in a protected environment
RESUMO A cultura da melancia apresenta grande importância econômica e social. Paralelamente, novos nichos de mercado são requeridos pelos consumidores, a fim de fornecer produtos diferenciados, dentre os quais destaca-se a minimelancia. Objetivou-se avaliar o desempenho agronômico e a qualidade de frutos de minimelancia cultivados em fibra de casca de co

9. Genetic evaluation of Pinus taeda clones from somatic embryogenesis and their genotype x environment interaction
Abstract The objective of this study was to evaluate the genotype x environment interaction and to estimate the genetic components of variance and mean using mixed models in early selection of 238 clones of Pinus taeda propagated by somatic embryogenesis. The experiment consisted of a complete blocks design, with 12 replications, with one plant per plot, in

10. Software Selegen-REML/BLUP: a useful tool for plant breeding
Abstract The software Selegen-REML/BLUP uses mixed models, and was developed to optimize the routine of plant breeding programs. It addresses the following plants categories: allogamous, automagous, of mixed mating system, and of clonal propagation. It considers several experimental designs, mating designs, genotype x environment interaction, experiments rep

11. Methylobacterium-plant interaction genes regulated by plant exudate and quorum sensing molecules
Bacteria from the genus Methylobacterium interact symbiotically (endophytically and epiphytically) with different plant species. These interactions can promote plant growth or induce systemic resistance, increasing plant fitness. The plant colonization is guided by molecular communication between bacteria-bacteria and bacteria-plants, where the bacteria reco

12. Calibração do modelo DSSAT/CANEGRO para a cana-de-açúcar e seu uso para a avaliação do impacto das mudanças climáticas / Calibration DSSAT/CANEGRO model for sugarcane and its use for the assessment of the impact of climate change
O presente trabalho teve como área de estudo o município de Juazeiro, Bahia, na região semi-árida do Nordeste brasileiro (9o2807S; 40o2243O; 386m de altitude). O objetivo foi calibrar o modelo DSSAT/CANEGRO e analisar o impacto das mudanças climáticas na produtividade da cana-de-açúcar irrigada para o cenário atual, (2007/2008) e para projeções fu
