25. Intraspecific tetraploid hybrids of Paspalum notatum: agronomic evaluation of segregating progeny
ABSTRACT: For many decades, animal production in southern Brazil has been based on native forage grasses. Paspalum notatum Flügge (bahiagrass) is one of the most frequently used native grass in southern Brazil. The native germplasm of P. notatum is tetraploid and displays apomictic reproduction; hence, chromosome doubling of sexual diploid accessions is req

26. Explaining Defense Cooperation With Process-tracing: the Brazilian Proposal for the Creation of UNASUR South American Defense Council
Abstract How can defense cooperation with process-tracing methodology be explained? To answer this question, this paper tests the ability of process-tracing explanations in the case of the Brazilian proposal for the creation of the Union of South American Nation’s (UNASUR) South American Defense Council (CDS). Combining process-tracing methodology with a c

27. Imputation of genetic composition for missing pedigree data in Serrasalmidae using morphometric data
ABSTRACT This study aimed to impute the genetic makeup of individual fishes of Serrasalmidae family on the basis of body weight and morphometric measurements. Eighty-three juveniles, belonging to the genetic groups Pacu, Pirapitinga, Tambaqui, Tambacu, Tambatinga, Patinga, Paqui and Piraqui, were separated into 16 water tanks in a recirculation system, with

28. Diallel analysis in agronomic traits of Jatropha
Abstract The objectives of this study were to estimate the general and specific combining ability of the parents, and to verify the existence of maternal effect and inbreeding depression in Jatropha. The experiment was carried out from 2010 to 2015, in the municipality of Planaltina, Distrito Federal. The following traits were evaluated: plant height, stem d

29. Combining ability of potato parents for tuber appearance and tuber yield component traits
Abstract The purpose of this study was to estimate the combining ability between two groups of potato parents in early generations of selection. Twelve potato families, derived from two groups of parents crossed in a 4x3 partial diallel design, were evaluated, in a randomized complete block design with three replications. Additive effects of genes were predo

30. Combining ability of sugarcane genotypes based on the selection rates of single cross families
Abstract This study evaluated the genetic potential of parents used in sugarcane genetic breeding programs based on the performance of previously conducted single crosses. The average selection rate of each family, predicted using Best Linear Unbiased Prediction (BLUP) procedure, was used as a surrogate to the cross performance in the initial evaluation phas

31. Genetic effects and potential parents in cowpea
ABSTRACT Six cowpea genotypes and their F2 hybrid combinations were evaluated for general and specific combining ability. The Griffing's diallel cross design, Method 2, and mixed model B were used. The genotypes and hybrids differed statistically (p <0.01) for the 10 studied traits. With regard to the general and specific combining ability, there were statis

32. ESTRATÉGIAS DE SÍNTESE NA DESCOBERTA DE FÁRMACOS: O EMPREGO DA SÍNTESE ORIENTADA PELA DIVERSIDADE ESTRUTURAL
Drug discovery often involves screening synthetic small molecules for their ability to bind to a macromolecular target. Target-Oriented Synthesis of a specific compound or a focused library can be planned combining retrosynthetic analysis and rational drug design. Biologically active molecules also can be identified through the unfocused screening of compoun

33. Resistance to Fusarium wilt in common bean
Abstract In breeding programs, understanding the potential of parents should be a way to spend significantly less time and costs to obtain new cultivars. For this, the objective of this study was to estimate the general and specific combining ability of parents aiming common bean breeding for resistance to Fusarium wilt (FW) based on disease severity and red

34. Combining the Pharmacophore Features of Coumarins and 1,4-Substituted 1,2,3-Triazoles to Design New Acetylcholinesterase Inhibitors: Fast and Easy Generation of 4-Methylcoumarins/1,2,3-triazoles Conjugates via Click Chemistry
Coumarins are a large class of compounds that display a range of interesting biological properties, being considered privileged structures because of the ability of their 2H-chromen-2-one nuclei to bind to multiple pharmacological targets. We hypothesized that the linkage of a second pharmacophore nucleus to the 2H-chromen-2-one core, the 1,2,3-triazole moie

35. Combining ability and heterosis of relevant fruit traits of tomato genotypes for industrial processing
The objective was to estimate the combining ability of lines and heterosis in industrial tomato genotypes for the identification of those with good potential for breeding programs. Ten lines of industrial tomato, 45 hybrids derived from a complete diallel and two commercial check cultivars were evaluated. The combining ability of tomato lines and heterosis o

36. The best of both worlds: Phylogenetic eigenvector regression and mapping
Eigenfunction analyses have been widely used to model patterns of autocorrelation in time, space and phylogeny. In a phylogenetic context, Diniz-Filho et al. (1998) proposed what they called Phylogenetic Eigenvector Regression (PVR), in which pairwise phylogenetic distances among species are submitted to a Principal Coordinate Analysis, and eigenvectors are
