Colletotrichum lindemuthianum; Molecular markers; Parent selection; Phaseolus vulgaris; Plant breeding

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

Genetic diversity; Germplasm collection; Molecular markers; Vigna unguiculata

The cowpea, Vigna unguiculata (Fabeaceae) is widely cultivated in semi-arid regions, such as northeast Brazil. Due to the low crop yields in this region, it would be useful to develop cultivars adapted to these climate conditions. Landraces are seen as an important source of germplasm to be used in breeding programs of this species due to their good adaptation to the environment, but ... more

Breeding programs; Legumes; Molecular markers; Variability

Genetic diversity is the basis for genetic improvement as it can provide the basis for new cultivars. Stylosanthes scabra is a grasslands legume that presents potential economic importance in tropical and subtropical regions. Plants of the genus Stylosanthes naturally occur in semiarid native pastures in northeastern Brazil and are highly favored ... more

Common bean breeding; Disease resistance; Molecular markers; Phaseolus vulgaris; Progenies; Seed yield

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

Genetic diversity; Genomic library; Molecular markers; Neutral markers; SSR

Microsatellite markers, also known as single sequence repeats (SSRs), are highly polymorphic, fast evolving, and regarded as neutral markers. Due to these traits, they have been widely used in population studies. The development of SSRs for a given species opens possibilities for their application in population studies of other species that are phylogenetically ... more

Coffee cultivars; genetic breeding; Genetic divergence; Germplasm evaluation; Molecular markers

Brazil is the world largest producer and exporter of Coffea arabica. In this country, numerous breeding programs have generated a great multiplicity of cultivars with expressive productivity that are adapted to the different regions. Evaluating genetic diversity is critical since it provides parameters for defining breeding strategies. We estimated the ... more

Artificial hybridization; Groundnut; peanut; Pollen; Pre-breeding; Wild species

The peanut (Arachis hypogaea) is an important food crop in much of the tropical and semi-tropical parts of the world. The peanut is an allotetraploid with an AABB genome formula derived from diploids A. duranensis (A genome) and A. ipaënsis (B genome). The success of an introgression program that aims to improve cultivated varieties of the peanut depends on ... more

Characterization; Germplasm; Groundnut; interspecific hybrid; Pollen viability; Wild species

The primary gene pool of the cultivated peanut (Arachis hypogaea L., allotetraploid AABB) is very narrow for some important characteristics, such as resistance to pests and diseases. However, the Arachis wild diploid species, particularly those from the section Arachis, still have these characteristics. To improve peanut crops, genes from the wild species can be ... more

Cassava breeding; Cerrado biome; Hybrid; Taxonomic key; Wild species

In this study, we describe the petiole anatomy of six wild cassava (Manihot) species, one hybrid, and two cultivars of Manihot esculenta, in order to identify their dominant anatomical patterns and relate them to possible adaptations to abiotic factors in the Cerrado biome. The median parts of several petiole samples were transversally and longitudinally sectioned and ... more
