The purpose of this work was to compare the SPD (Single Pod Descent) and SPDS (Single Pod Descent with Selection) methods for segregating generation advancement in soybean breeding. Sixteen populations derived from crosses among Japanese and adapted Brazilian soybean were used. The traits, number of days to flowering (NDF) and to maturity (NDM), plant height at flowering (PHF) and at maturity (PHM), and individual plant yield (IPY) were assessed. The populations obtained by SPDS showed values close to the variation in the populations obtained by SPD. Regression through the origin showed that both methods were equivalent for NDM in the F3 generation and for NDF in the F4 generation. For all other trait/generation combinations, SPDS yielded superior means.... |

During 1995/96 and 1996/97, experiments were carried out at Londrina State University, aiming at quantifying the oil and protein contents in two groups of soybean genotypes; estimating the phenotypic, genotypic and environmental correlations existent among oil, protein content and seed size, and identifying genotypes for direct human consumption with high protein content. The evaluated characters were Weight of a Hundred Seeds (WHS), expressed in grams/100 seeds, Oil Content (OC) and Protein Content (PC), expressed in %. In the experiment carried out in the field, OC ranged from 12 to 20.37 % and PC from 35.66 to 41.75% while in the experiment carried out in the greenhouse OC ranged from 12.26 to 21.79 % and PC from 32.95 to 41.56 % . The correlations... |

The present study was carried out to determine the contribution of main stems and tillers to the total yield of two wheat cultivars (Triticum aestivum L.), Cocoraque and BH-1146, under two water treatments: a) normal field conditions, and; b) irrigation, in Londrina, PR, Brazil. The experiment was an eight replication randomized complete block design with treatments arranged in split-plots. Data on total grain yield, main stem grain yield, tillers grain yield, the ratio between tiller and total grain yield, yield components and other 17 traits were collected. The cultivar BH-1146 had a higher total grain yield in relation to Cocoraque under normal field conditions; i, e., under water stress. Main stem grain yield responded positively and significantly to... |

This work was conducted at the Universidade Estadual de Londrina (UEL), in Londrina, State of Paraná, Brazil, with the goal to study food-type soybean (Glycine max (L.) Merrill) genotypes performance for use in cultivation or crosses. A total of 104 genotypes were analyzed: 88 were food-type with large seeds, eight were food-type with small seeds, and eight-grain types adapted cultivars. The experimental plan was in randomized complete block design with four replications, and 12 traits of agronomic importance were considered. Genetic diversity was observed in the food-type germplasm. There were some genotypes with high yield adapted to a normal period of sowing. Soybean genetic improvement programs for direct human consumption in Brazil, either by means of... |

The objective of this work was to estimate the coefficient of parentage and to understand the genetic structure of 90 elite soybean cultivars, which are adapted to different Brazilian environments. A total of 4,005 coefficients of parentage (f) were obtained and used to group the cultivars by UPGMA method. The constructed dendrogram showed several related cultivar groups which shared similar ancestors and clearly showed the genetic structure of the main Brazilian cultivars. Effective population sizes (Ne) were also estimated for cultivars in different generations. The average f = 0.2124 value, obtained from cultivars classified into four decades according to the release year, suggested effective soybean population sizes of 11 and 13 calculated using... |

Este trabalho visou a avaliar o comportamento de quatro genótipos de banana: híbridos FHIA 1, BRS FHIA 18 e as cultivares Caipira e Prata-Anã durante o primeiro ciclo de produção, nas condições edafoclimáticas de Bonito, Mato Grosso do Sul. As maiores produtividades foram observadas para os híbridos FHIA 1 e BRS FHIA 18, com médias de 26,95 e 24,5 t/ha, respectivamente. Os híbridos foram superiores, estatisticamente, para as características massa do cacho (MC), número de pencas (NP), massa da ráquis (MR) e massa total de frutos (MTF). Os híbridos e a cultivar Caipira apresentaram médias semelhantes para número total de frutos (NTF), destacando-se o híbrido BRS FHIA 18 com 119,30. Quanto ao ciclo de produção, o híbrido BRS FHIA 18 e as cultivares... |

A síndrome da morte súbita (SMS), causada por Fusarium solani f. sp. glycines, tem se mostrado uma das mais importantes doenças da soja, devido aos prejuízos provocados e à dificuldade de controle. Este trabalho teve como objetivo selecionar os métodos de inoculação mais eficientes para a avaliação de resistência genética de genótipos de soja à SMS. Foram realizados dois experimentos em delineamento de blocos casualizados, sendo seis tratamentos e 12 repetições, no primeiro experimento, e seis tratamentos e 16 repetições, no segundo. Cada parcela foi constituída por um vaso contendo uma planta de soja da cultivar FT Estrela, altamente suscetível à SMS e outra planta de "Conquista", moderadamente resistente. As plantas foram avaliadas quanto à incidência e... |
