Última Genetic Parameters and Predictive Genetic Gain in Maize with Modified Recurrent Selection Method Chilean J. Agric. Res. Afonso Doná,Anderson; Vieira Miranda,Glauco; Oliveira DeLima,Rodrigo; Gonçalves Chaves,Luciana; Gomes e Gama,Elto Eugênio. The modified recurrent selection method suggests a less productive population to test the other population more productive and itself aiming to have more genetic gains than tradition recurrent selection method that uses one population to test the other one. The objectives of this work were to estimate the genetic components, to predict and to evaluate the genetic gains of the SynFlint and Syndent populations of maize (Zea mays L.), applying a modified recurrent selection method. Two recombination cycles were carried out, with 144 Si progeny per cycle. These progenies were test crossed with SynFlint, generating a SynFlint x Syndent inter-population and a SynFlint x SynFlint intra-population. The progenies were evaluated in five environments in the first... Tipo: Journal article Palavras-chave: Breeding methods; Genetic variability. Ano: 2012 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-58392012000100006 Inbreeding depression and genetic components for popping expansion and other traits in Brazilian populations of popcorn Ciencia e Investigación Agraria Arnhold,Emmanuel; Soriano Viana,José Marcelo; Mora,Freddy; Vieira Miranda,Glauco; Gonçalves Silva,Ricardo. The aim of the study was to assess inbreeding depression and determine genetic components in landrace populations of popcorn. Six Brazilian popcorn landraces: Amarelo, Beija-Flor, Branco, Rosa-claro, Roxo and Viçosa, were subjected to self-pollination. Experiments with SO populations and their selfing populations (SI) were conducted in a randomized complete block design. The estimates of inbreeding depression varied from 1.2% (popping expansion) to 79% (grain yield). The gene action was predominantly additive for plant height, ear height and hundred-grain-weight. The dominance genetic effects were important for index of prolificacy and grain yield. The genetic effect of popping expansion was bidirectional with nuil dominance and a predominance of additive...
