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
The amount of absorbed phosphorus directly impacts on the growth and grain yield of common bean plants. We evaluated dry matter production at different growth stages and grain yield of common bean genotypes in response to phosphorus availability in a nutrient solution and examined possible associations between these characters. The experiment was carried out in a ... more
Nitrogen (N) is the most important soil nutrient for common beans; the main sources are mineral N fertilizers and symbiotic N fixation (SNF). The common bean (Phaseolus vulgaris) is a N fixing species, but breeding programs have neglected this fact. We investigates black seeded elite lines grown with mineral N fertilization or using inoculation with ... more
Fusarium wilt is a serious soil disease affecting common bean cultivation, especially crops under a central pivot irrigation system. Our objective was to identify bean lines that combine resistance to Fusarium wilt in the field with other desirable traits. Twenty-eight randomized block trials with three replicates were conducted in the rainy, winter, and dry ... more
A possible strategy to increase grain yield in common beans (Phaseolus vulgaris) is to obtain lines with earlier flowering and a longer grain filling period, associated with a higher dry matter accumulation rate. We examined the genetic control of these traits to investigate whether it is possible to select lines with earlier flowering, a longer period of ... more
Conservation of seeds ex situ is an important strategy for maintaining genetic resources. Mulatinho type common beans are widely cultivated and consumed in regions with extreme climatic conditions with semi-arid characteristics, including low fertility soils, and a dry and hot climate, such as in northern Minas Gerais state and the northeast region of ... more
High temperature is one of the main environmental factors that limit crop performance. It may also influence seed formation and quality. We compared the effect of high temperatures on seed darkening and cooking time of 12 genotypes of common beans. The experiments were sown in summer and in fall/winter growing seasons in three municipalities of São Paulo state ( ... more
