| ABSTRACT In Brazil, as the soybean crop expands the losses caused by nematodes as well as its incidence in producing areas have increased. Therefore, this work aimed to develop a non-genetically modified soybean which combines desirable traits as the root-knot nematode resistance, early-maturity, high seed yielding, and high oil and protein contents. Consequently, seeds (F2) derived from the double-crossing between (Guarani x Sambaiba) x (M Soy 6101 x Conquista) were bulked to grow the F3 generation. Following generations were advanced by the SSD method of breeding until F6. Thus, plants showing superior characteristics were planted separately to perform progeny tests and then advanced breeding lines were thoroughly tested and compared to standards in... |

| The objective of the present study was to evaluate 44 soybean octuple crosses in the F4:3[8] and F5:3[8] generations in order to select progenies superior for seed oil yield (OY) and other important agronomic characteristics. Octuple crosses were hybridized in a chain mating system. In one group, crosses were carried out for three generations with the adapted x exotic parents until octuple crosses with 75% adapted genes and 25% exotic genes were obtained. In a second group, hybridization of adapted x adapted parents originated crosses with 100% adapted genes. During the growing season 1994/95, the progenies F4:3[8] were evaluated by using the augmented block design. The progenies F5:3[8] were evaluated during the growing season 1995/96 in three experiments... |

| Abstract: The objective of this work was to evaluate the physiological and production parameters of soybean (Glycine max) cultivars of determinate and indeterminate growth habits, in three levels of soil moisture. Three cultivars of determinate growth habit and three of indeterminate growth, at the beginning of the reproductive stage, were subjected to three levels of soil moisture: control, moisture at field capacity; moderated, 50% of the control level; and severe, 25% of the control level. Leaf gas exchange, xylem-water potential, chlorophyll content, chlorophyll a fluorescence, plant dry matter, and grain yield per plant were evaluated. The cultivars of indeterminate growth habit showed the greatest values for stomatal conductance and CO2 assimilation... |

| A fim de ampliar as opções ao cultivo da soja, a Universidade Federal de Uberlândia lançou a cultivar UFUS-Imperial, proveniente do cruzamento entre (Msoy 8411xMsoy 8914) x (Emgopa 313xTucano). A cultivar apresentou resistência ao acamamento, à deiscência da vagem e aos patógenos: Fusarium solani, Cercospora sojina, Peronospora manshurica, Xanthomonas campestris pv. glycines e Diaporthe phaseolorum f.sp. meridionalis, e resistência parcial a Septoria glycines, Erysiphe diffusa e Phakopsora pachyrhizi. O rendimento dessa cultivar, em ensaios regionais, foi 45% superior ao da testemunha Msoy 6101, e é indicada para o Estado de Mato Grosso. |

| A busca de alta produtividade na cultura da soja, sem onerar os custos de produção, é o objetivo do melhoramento genético. A cultivar UFUS Impacta é um genótipo de soja proveniente do cruzamento entre Cristalina RCH e IAC 100, de ciclo semi-tardio, com produtividade média superior às testemunhas Garantia e Emgopa 313 RCH. É resistente às principais moléstias da soja e indicada para cultivo no Estado de Minas Gerais. |
