Statistical significance, selection accuracy, and experimental precision in plant breeding

Marcos Deon Vilela de Resende & Rodrigo Silva Alves
Abstract Genetic selection efficiency is measured by accuracy. Model selection relies on hypothesis testing with effectiveness given by statistical significance (p-value). Estimates of selection accuracy are based on variance parameters and precision. Model selection considers the amount of genetic variability and significance of effects. Questions arise as to which one to use: accuracy or p-value? We show there is a link between the two and both may be used. We derive equations for accuracy in...

Relationship of woody species composition with edaphic characteristics in threatened riparian Atlantic Forest remnants in the upper Rio Doce basin, Brazil

Yule Nunes, João Carlos Figueiredo, Marly Antonielle Ávila, Camila Souza, José Gustavo Neves, Glaúcia Tolentino, Yumi Oki, Islaine Francielly Azevedo, Daniel Negreiros, João Herbert Viana, Rubens Santos, Rúbia Fonseca & Geraldo Wilson Fernandes
Studies on the composition, richness, and diversity of plant species in tropical communities are essential for understanding relevant ecological processes and for developing appropriate conservation policies. Considering that areas subject to direct impacts due to dam breach may in the long-term present changes in species composition and in soil parameters, we evaluated the composition of the flora, described the current vegetation profile, and evaluated whether differences in species composition was influenced by soil variables of...

Supplementary material from \"Acquisition of novel muscles enabled protruding and retracting mechanisms of female penis in sex-role reversed cave insects\"

Zixin Cheng, Yoshitaka Kamimura, Rodrigo L. Ferreira, Charles Lienhard & Kazunori Yoshizawa
Brazilian sex-role reversed cave insects (genus Neotrogla) have a striking structure called the gynosome (or female penis), which deeply penetrates male vagina-like genitalia during copulation to receive nutritious semen. However, the protruding and retracting mechanisms of the female penis, including their evolutionary origin, are poorly understood. By using the micro-computed tomography (= µCT), we compared the genital morphology and musculature between species with a gynosome and others lacking this structure. As a result, we discovered...

Screening coffee genotypes for brown eye spot resistance in Brazil

Juliana Ramos, Mario Lucio Rezende, Deila Botelho, Renata Pereira, Tharyn Reichel, André Balieiro, Gustavo Botega & Juliana Rezende
Several researchers have attempted to develop coffee plants that are resistant to brown eye spot (BES); however, no coffee cultivars are resistant to the disease. In the present study, a blend of strains from Cercospora coffeicola was inoculated into 19 Brazilian commercial cultivars and 41 accessions from the Germplasm Collection of Minas Gerais to evaluate the genetic resistance ability within the population and select superior genotypes for the breeding program. After predicting the genotypic values...

Genotypic diversity and genetic parameters of 'Tahiti' acid lime using different rootstocks

Renan Garcia Malikouski, Marco Antônio Peixoto, Filipe Manoel Ferreira, Andréia Lopes de Morais, Rodrigo Silva Alves, Moises Zucoloto, Dimmy Herllen Silveira Gomes Barbosa & Leonardo Lopes Bhering
Abstract The objective of this work was to estimate the genetic parameters and to evaluate the genotypic diversity of 12 'Tahiti' acid lime (Citrus latifolia) genotypes grafted onto two rootstocks. The experiment was carried out from July 2017 to January 2019, in the municipality of São Mateus, in the state of Espírito Santo, Brazil. Vegetative (stem diameter, canopy projection diameter, and plant height), productive (yield and fruit number), and fruit quality (fruit diameter, soluble solids...

Felipe, Ricardo García, José Luis Gómez Hechavarría, Aretha Franklin Guimarães, Ernesto Medina, Adrian L.D. Paul, Nishanta Rajakaruna, Carla Restrepo, Stefan Siebert, Eduardo Van Den Berg, Antony Van Der Ent & Grisel Velasquez
This is a compiled geospatial dataset in ESRI polygon shapefile format of ultramafic soils of the neotropics showing the location of ultramafic soils in Guatemala, Cuba, Dominican Republic, Puerto Rico, Costa Rica, Colombia, Argentina, Chile, Venezuela, Ecuador, Brazil, Suriname, French Guiana, and Bolivia. The data are derived from seven geospatial datasets. Original datasets were subset to include only ultramafic areas, datasets were assigned a common projection (WGS84), attribute tables were reconciled to a common set...
