Phaseolus Vulgaris
Genetic potential of common bean progenies selected for crude fiber content obtained through different breeding methods
Authors: V.A.P. J�ºnior, 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 g.. Read More»

Diallel analysis to choose parents for black bean (Phaseolus vulgaris L.) breeding
Authors: L.M. Moura, P.C.S. Carneiro, N.M. Vale, L.D. Barili, L.C. Silva, J.E.S. Carneiro and C.D. Cruz
In this study, conducted in two different seasons, we aimed to choose parents to obtain promising segregating populations for the extraction of black bean (Phaseolus vulgaris L.) lines that are superior in terms of disease resistance, plant architecture, and grain yield. Twelve parents were arranged in two groups to compose a .. Read More»

Simultaneous selection in beans for stability and high agronomic performance
Authors: N.D. Ribeiro, C.R. Casagrande, H.C. Mezzomo, M.T.D.F. Possobom, S. de M. Steckling and G.R. Kl�¤sener
The objective of this study was to select common bean cultivars based on their stability for flowering, cycle, insertion of the first pod, grain yield, and high agronomic performance. Twenty experiments were carried out between 2000 and 2014, during two growing seasons, in Rio Grande do Sul, Brazil. The Eberhart and Russel, an.. Read More»

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

Genetic control and estimation of genetic parameters for seed-coat darkening of carioca beans
Authors: F.C. Silva, P.G.S. Melo, H.S. Pereira and L.C. Melo
The maintenance of the light color of the grains of carioca beans is a requirement for the development of new cultivars of common beans because it enables the storage of grains for long periods so that they may be traded at a proper opportunity. Crosses of cultivar BRSMG Madrepérola, which presents slow grain darkening,.. Read More»

Genetic variability for iron and zinc content in common bean lines and interaction with water availability
Authors: H.S. Pereira, M.J. Del Peloso, P.Z. Bassinello, C.M. Guimar�£es, 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 o.. Read More»

Genetic potential of common bean progenies obtained by different breeding methods evaluated in various environments
Authors: V.A. Pontes J�ºnior, 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 popu.. Read More»

Geometry applied to breeding common beans (Phaseolus vulgaris)
Authors: J.G. Lima and M.A.P. Ramalho
The primary components of common bean (Phaseolus vulgaris) grain yield (W) are the number of pods (X), the number of grains per pod (Y), and the weight of the grains (Z). In 1964, Grafius suggested using geometry in plant breeding; W corresponds to the volume of a parallelepiped with three axes, X, Y, and Z. Because the cube i.. Read More»

Genetic improvement of plant architecture in the common bean
Authors: V.M.P. Silva, J.A.N. Menezes J�ºnior, P.C.S. Carneiro2, J.E.S. Carneiro and C.D. Cruz
Knowledge of genetic control of plant architecture in the common bean can help breeders define the most adequate breeding strategy to optimize gains. We examined genetic control of plant architecture in the common bean by means of partial diallel crosses. Fourteen bean lines were crossed under a partial diallel scheme, in which group 1 was composed of 8 e.. Read More»
