de Azevedo, Luís Antônio Siqueira; Juliatti, Fernando Cezar; Barreto, Modesto [UNESP]Made available in DSpace on 2022-04-28T20:44:39Z (GMT). No. of bitstreams: 0 Previous issue date: 2007-01-01; The aim of the present study, was to quantify the resistance in fifty soybean genotipes of the cerrado region to the rust caused by Phakopsora pachyrhizi .One experiment in greenhouse were conducted in Uberlândia, MG from January to July 2004. Average latent period, number of pustules per cm2 and diseas...
Genetic parameters and line selection of Cucurbita pepo based on selection indices
Beloti, Igor Forigo; Maciel, Gabriel Mascarenhas; Juliatti, Fernando Cezar; Finzi, Rafael Resende; Cardoso, Daniel Bonifácio OliveiraIn the improvement of pumpkins, the selection based on one or a few characters of interest tends to be less efficient, leading to a superior product only compared to the few characters selected. To maximize the simultaneous selection of multiple characteristics of interest, selection indexes are used to obtain a numerical value resulting from the combination of the characters on which the simultaneous selection...

Seleiman, Mahmoud F.; Selim, Shaimaa; Alhammad, Bushra Ahmed; Alharbi, Basmah M.; Juliatti, Fernando CezarThe whole world is in a great danger due to the novel coronavirus (COVID-19) pandemic. In December 2019, the outbreak of COVID-19 took place in Wuhan, China and then rapidly spread all over the world. The current study provides potential expectations for the adverse impact of (COVID-19). The global infection affected globe on agricultural level such as agriculture, food supplies and animal production sectors. T...
A critical-point yield model to appraise the damage caused to soybean by white-...
Reis, Erlei M.; Zanatta, Mateus; Juliatti, Fernando Cezar; Campos, Hercules D.; Silva, Luis Henrique Carregal P.; Meyer, Maurício C.; Nunes Junior, JoséA model to estimate the damage caused by white mold to soybean yield from experimental field data gathered during the summer season of 2009-10 was generated. Six soybean cultivars were grown on six sites of the Cerrados region, resulting in a total of nine separate experiments. The gradient of disease intensity (plant stem incidence) and yield was generated through the application of different fungicides and ra...
Emergence and epidemics of a new disease in araguaia valley: anthracnosis of co...
Juliatti, Fernando Cezar; Juliatti, Fernanda Cristina; Juliatti, Breno Cezar Marinho; Paula, Cristiane Aparecida deCotton culture (Gossypium hirsutum L.) is trending in an upward expansion amidst Brazilian “cerrado”. Due this growth, new pathosystems are growing in incidence on tropical fields in the region of Araguaia Valley - MT. Surveys and material collection were conducted out in production areas on two counties (Bom Jesus - MT and Canarana – MT), both regions represents a total amount of 50.000 hectares of cultivated ...
Morphoagronomic characters and partial resistance to soybean rust in early soyb...
Oliveira, Morony Martins; Juliatti, Fernando CezarSoybean crop, despite the technological evolution, did not reach an average of 4,000 kg ha-1 in Brazil due to the factors of climate, nutritional and soil fertility, genetics and phytosanitary problems. Among them is the rust-soy disease of soybean, caused by the fungus Phakopsora pachyrhizi Syd. & Syd., one of the most severe, with damage up to 100%. Among the management strategies are the use of early gen...
Diversity of fungi in seeds of hymenaea stignocarpa and hymenaea courbaril befo...
Costa, Nayara Cecília Rodrigues; Carvalho, Fábio Janoni; Juliatti, Fernando Cezar; Castro, Mariana Viana; da Cunha, Walter VieiraThe recovery of degraded areas led to an increase of native forest seedlings production. Jatoba-do-cerrado (Hymenaea stignocarpa Mart.) and jatoba-da-mata (Hymenaea courbaril L.), native species of the Brazilian Cerrado, are widely used for the recovery of this biome. Although forest species present a diversity of pathogens disseminated by seeds, few studies have been published and no study was found for jatoba...
Partial resistance of soybean lines to asian rust and white mold
Santos Martins, Juliana Araújo; Alves, Augusto Borges e; Garcez, Michel; Juliatti, Fernando CezarSoybean Asian rust and white mold stand out to cause great problems to soybean producing regions in Brazil. The aim of this study was to evaluate the partial resistance of soybean lines to Asian rust and white mold. In order to assess the resistance of soybean to Asian rust, 19 early maturing soybean lines were used in an experiment in a greenhouse. Four severity evaluation were carried and the area under the d...
New high-yielding conventional soybean adapted to the states of Goiás, Minas Ge...
Hamawaki, Raphael Lemes; Hamawaki, Osvaldo Toshiyuki; Nogueira, Ana Paula Oliveira; Juliatti, Fernando Cezar; Glasenapp, Jacqueline SiqueiraThis paper aims to present the features of the new soybean cultivar UFUS Milionária, which was developed by the Soybean Improvement Program of the Federal University of Uberlândia (UFU) through crossing between IAC-100 and Cristalina RCH cultivars, using the Single Seed Descent (SSD) method. UFUS Milionária is resistant to many diseases caused by the fungus, bacteria, and virus. In addition, it also has been pr...
Evaluation of the gelatin technique for the preservation of phytopathogenic fungi
Beloti, Igor Forigo; Juliatti, Breno Cezar Marinho; Juliatti, Fernando CezarThe preservation methods for fungi have great importance in ex situ collections, representing important biological heritage, useful for mycologists and plant pathologists in several scientific works. However, there is a lack of studies for a suiTable and efficient preservation method for the different groups of fungi. Although, the most appropriate is the one that maintain, even after long periods, the original...
