The main goal of this work was to select resistance sources to common bean anthracnose by field phenotyping and DNA marker-assisted screening. Fifty-five common bean genotypes, including differential varieties, characterized resistance sources, elite lines, cultivars and controls, were evaluated in a field inoculation trial and screened with SCAR markers linked to ... more
We examined the general and specific combining abilities of common bean cultivars and varieties and tested promising hybrid combinations for the development of productive strains. Two cultivars (IPR Uirapuru and IPR Campos Gerais) and five local varieties (BGU-1, BGU-7, BGU-13, BGU-25 and BGU-36) were planted in a full diallel cross. Treatments were assessed based ... more
The objectives of this study were to select promising common bean populations for high iron and zinc contents (FeC and ZnC), seed yield and 100-seed weight, to study the genetic control of these traits and to select parents for high FeC and ZnC based on a diallele analysis. Fifteen populations were obtained from crosses among six parents selected for high FeC and ... more
The search for genetic material of snap beans with desirable yield traits is of utmost importance for yield increase in Brazil. We evaluated 12 snap bean genotypes by diallel crosses that presented characteristics of interest, so as to select the best genitors to generate productive populations in the snap bean breeding program of the Universidade Estadual do Norte ... more
The development of common bean cultivars with biofortified grains for macrominerals and a seed coat color pattern that satisfies consumer preference is a new demand of breeding programs. However, combined selection for seed coat color and macromineral concentrations in common beans is unprecedented. The objectives of this work were to obtain estimates of genetic ... more
The common bean is widely distributed throughout Brazil and within Mato Grosso state. It has wide genetic variability and adaptability to various environmental conditions. We evaluated the genetic divergence and agronomic performance of common bean genotypes in order to initiate a bean breeding program in the region of Cáceres, MT. We included 58 genotypes (40 ... more
Diallel analysis and field tests have not been used in selecting for resistance to fusarium wilt in common beans (dry beans, Phaseolus vulgaris). Our goal was to select parents and segregating populations of dry bean (common bean) with black seed coat that are resistant to fusarium wilt and have high yield and high seed weight. Eight common bean cultivars ... more
Fusarium wilt caused by the fungus Fusarium oxysporum f. sp. phaseoli (Fop) is one of the most important diseases of common bean and occurs in many regions of the world. However, there is little available information that could elucidate when and where the fungus attacks common bean plants. To study the colonization of common bean by this ... more
Common beans are a key source of protein and are consumed daily by most of the Brazilian population. More than 70% of what is consumed in this country is classified as carioca beans, based on seed qualities and appearance. We evaluated progenies of carioca common beans of the Brazilian agriculture research agency (Embrapa) recurrent selection program. This ... more
Recently, carbon nanotubes (CNTs) are gaining attention in the field of agriculture as advanced approaches to minimize toxicity of mycotoxins for crop plants. We examined whether MWCNTs can be used to alleviate genotoxicity and DNA damage induced by ochratoxin A (OTA) in the common bean (Phaseolus vulgaris) by comparing the action of three OTA doses, prior ... more
