Abstract The common bean is affected by several pathogens that can cause severe yield losses. Here we report the introgression of resistance genes to anthracnose, angular leaf spot and rust in ‘carioca‐type’ cultivar ‘Rudá’. Initially, four backcross (BC) lines were obtained using ‘TO’, ‘AB 136′, ‘Ouro Negro’ ‘AND 277’ as donor parents. Molecular fingerprinting was used select genetically closer recurrent parent. relative genetic distances between ‘Rudá’ BC varied 0.0% 1.99%. intercrossed...

A busca por alimentos mais sustentáveis, produtivos e economicamente viáveis têm sido uma prioridade para organizações governamentais. Os insetos, em particular larvas de tenébrio (Tenebrio molitor L.), destacam-se devido à sua excelente composição nutricional rica proteínas, superando diferentes fontes tradicionais. Além disso, reproduzem-se na escala semanas, ocupam pouco espaço físico demandam menores investimentos manutenções. O objetivo deste trabalho foi validar um protocolo extração...

The main goal of the present work was to characterize rust resistance (RR) gene in Mesoamerican common bean cultivar Ouro Negro, temporarily named Ur‐OuroNegro or Ur‐ON , which is RR source used Brazil. spectrum presented by cv. Negro compared with those other lines harbouring known genes when inoculated nine selected races Uromyces appendiculatus causal agent rust. In addition, all were screened molecular markers linked order identify additional evidence for presence alleles this locus...

Abstract: The objective of this work was to evaluate the efficiency methods Eberhart & Russell and Lin Binns, modified for automation decision-making by fuzzy logic, in assessing adaptability stability common bean (Phaseolus vulgaris) cultivars. Eighteen cultivars “carioca” commercial group were evaluated 11 environments, Brazil. All results obtained programming R software. developed controllers based on inference system Mamdani. This modeled enable interpretations method alone or...

Angular leaf spot (ALS), incited by the fungus Pseudocercospora griseola, is a major disease affecting common bean. Important resistance sources have been identified and characterized: AND 277, BAT 332, Cornell 49-242, MAR-2, Mexico 54. P. griseola presents high physiological variability. The control of this kind pathogen requires continuous evaluation, including monitoring characterization pathogenic variability, eventual germplasm introgression genes in adapted cultivars. Cultivar Ouro...

The methods of Annicchiarico (1992) and Cruz et al. (1989) are widely used in phenotypic adaptability stability analyses plant breeding. In spite the importance these methodologies, their parameters difficult to interpret. aim this research was develop fuzzy controllers automate decision-making process employed by studies following adopted check efficiency using experimental data from common bean cultivars. Fuzzy have been developed based on Mamdani inference system proposed two studies. For...

The main goal of this work was to select resistance sources common bean anthracnose by field phenotyping and DNA marker-assisted screening.Fifty-five genotypes, including differential varieties, characterized sources, elite lines, cultivars controls, were evaluated in a inoculation trial screened with SCAR markers linked genes that are important Brazil.The carried out Santo Antônio de Goiás, GO, Brazil, during the fall/winter growing season 2014, using artificial mixture six races...

Twelve single-pustule isolates of Uromyces appendiculatus, the etiological agent common bean rust, were collected in state Minas Gerais, Brazil, and classified according to new international differential series binary nomenclature system proposed during 3rd Bean Rust Workshop. These have been used select rust-resistant genotypes a breeding program conducted by our group. The twelve into seven different physiological races: 21-3, 29-3, 53-3, 53-19, 61-3, 63-3 63-19. Races 61-3 most frequent...

Background and Aim: The term ESKAPE, recognized by the WHO, is an acronym, which refers to pathogens Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter spp., extremely virulent multidrug-resistant. Although used designate nosocomial pathogens, in a milking environment, strains of Methicillin-resistant S. aureus have been isolated from cattle diagnosed with clinical subclinical mastitis. Resistant may be involved...

The Staphylococcus aureus is the most common isolated microorganism in ruminant animal species diagnostic with clinical or subclinical mastitis.Dairy herds these diseases can transfer S. into milk supply, which lead to food poisoning humans.The objective of this study was evaluate profile antimicrobial susceptibility, presence femA gene, genetic relationships among isolates obtained from A.R.

The objective of this study was to evaluate the chemical attributes and quality an Oxisol after one year conversion degraded pasture into integrated production system. evaluated treatments were (PAST-Control); Eucalyptus, clone Urograndis 144 (Eucalyptus grandis x E. urophylla hybrid) intercropped with cor marandu grass (Brachiaria brizantha) (integration crop-livestock-forest system - ICLFS-M); maize perennial horse gram (Macrotyloma axillare) (ICLFS-HG); maize, java (ICLFS-M+J);...

A new methodology of inoculating Uromyces appendiculatus in tests aimed at evaluation common bean resistance to rust is proposed. The lines Golden Gate Wax (gene Ur-6) and Ouro Negro Ur-ON) were crossed obtain a F2 population, which was inoculated with race 29-3 U. appendiculatus. Race incompatible 'Ouro Negro' compatible 'Golden Wax'. Primary leaves ten-days-old plants detached by immersion into an inoculum suspension. Immediately following immersion, each leaf placed Petri dish containing...

O cártamo (Carthamus tinctorius L.) é uma espécie que tem grande potencial de inserção em regiões sofrem com o estresse hídrico, devido suas condições adaptabilidade, qualidades e aplicações. Nesse sentido, este estudo objetivou identificar acessos potenciais adaptações às edafoclimáticas norte-mineiras, visando fomentar um programa melhoramento. Para isso, 10 do foram avaliados por caracteres morfoagronômicos. Os a altura plantas, matéria seca da parte aérea, diâmetro caule, ramificação...
