Selection of resistance sources to common bean anthracnose by field phenotyping and DNA marker-assisted screening

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 r..

Genetic parameters and breeding strategies for high levels of iron and zinc in Phaseolus vulgaris L.

    S.M. Martins, P.G.S. Melo, L.C. Faria, T.L.P.O. Souza, L.C. Melo and H.S. Pereira

One of the current focus of common bean breeding programs in Brazil is to increase iron (FeC) and zinc content (ZnC) in grains. The objectives of this study were to estimate genetic parameters for FeC and ZnC in common bean, verify the need for conducting multi-site evaluation tests, identify elite lines that combine high FeC and ZnC with good adaptability, stabilit..

Genetic potential of common bean progenies obtained by different breeding methods evaluated in various environments

    V.A. Pontes Júnior, P.G.S. Melo, H.S. Pereira and L.C. Melo

Grain yield is strongly influenced by the environment, has polygenic and complex inheritance, and is a key trait in the selection and recommendation of cultivars. Breeding programs should efficiently explore the genetic variability resulting from crosses by selecting the most appropriate method for breeding in segregating populations. The goal of this study was to e.. Read More»

Genetic variability for iron and zinc content in common bean lines and interaction with water availability

    H.S. Pereira, M.J. Del Peloso, P.Z. Bassinello, C.M. Guimarães, L.C. Melo and L.C. Faria

The common bean is an important source of iron and zinc in humans. Increases in the contents of these minerals can combat mineral deficiencies, but these contents are influenced by environmental conditions. Thus, the objectives of this study were to investigate the interaction between common bean lines and water availability on iron and zinc contents (CFe and CZn, r.. Read More»

Differential interactions between Curtobacterium flaccumfaciens pv. flaccumfaciens and common bean

    S.C.D. Valdo, A. Wendland, L.G. Araújo, L.C. Melo, H.S. Pereira, P.G. Melo and L.C. Faria

Bacterial wilt of common bean caused by Curtobacterium flaccumfaciens pv. flaccumfaciens is an important disease in terms of economic importance. It reduces grain yield by colonizing xylem vessels, subsequently impeding the translocation of water and nutrients to the superior plant parts. The existence of physiological races in C. flaccumfaciens pv. flaccumfaciens h.. Read More»

Estimation of genetic parameters and selection of high-yielding, upright common bean lines with slow seed-coat darkening

    R.C. Alvares, F.C. Silva, L.C. Melo, P.G.S. Melo and H.S. Pereira

Slow seed coat darkening is desirable in common bean cultivars and genetic parameters are important to define breeding strategies. The aims of this study were to estimate genetic parameters for plant architecture, grain yield, grain size, and seed-coat darkening in common bean; identify any genetic association among these traits; and select lines that associate desi..

Genetic potential of common bean progenies selected for crude fiber content obtained through different breeding methods

    V.A.P. Júnior, P.G.S. Melo, H.S. Pereira, P.Z. Bassinello and L.C. Melo

Gastrointestinal health is of great importance due to the increasing consumption of functional foods, especially those concerning diets rich in fiber content. The common bean has been valorized as a nutritious food due to its appreciable fiber content and the fact that it is consumed in many countries. The current study aimed to evaluate and compare the genetic potential of common bean progenie.. Read More»

Genetic potential of black bean genotypes with predictable behaviors in multienvironment trials

    P.P. Torga, P.G.S. Melo, H.S. Pereira, L.C. Faria and L.C. Melo

The aim of this study was to evaluate the phenotypic stability and specific and broad adaptability of common black bean genotypes for the Central and Center-South regions of Brazil by using the Annicchiarico and AMMI (weighted average of absolute scores: WAAS, and weighted average of absolute scores and productivity: WAASP) methodologies. We carried out 69 trials, w.. Read More»

Backcross assisted by microsatellite markers in common bean

    L.K. Oliveira1,3, L.C. Melo2, C. Brondani3, M.J.D. Peloso2 and R.P.V. Brondani3

The objectives of the present study were to monitor the effect of backcrossing through microsatellite markers and to compare different marker assisted selection strategies. Four populations were developed using donor parents resistant to the bean golden mosaic virus and, for all crosses, only individuals resistant to the bean golden mosaic virus were backcrossed. For crosses ARC100-4 x DOR303 a.. Read More»

The identification of germplasm genetic variability in breeding programs of the common bean (Phaseolus vulgaris) is essential for determining the potential of each combination of parent plants to obtain superior genotypes. The present study aimed to estimate the extent of genetic diversity in 172 lines and cultivars of the common bean by integrating five tests of value for cultivation and use (.. Read More»
