Multivariate statistics applied to the reaction of common bean plants to parasitism by Meloidogyne javanica
Authors: L.N.S. Santos, P.D.S. Cabral, G.A.R. Neves, F.R. Alves, M.B. Teixeira1, F.N. Cunha1 N.F. Silva
The availability of common bean cultivars tolerant to Meloidogyne javanica is limited in Brazil. Thus, the present study aimed to evaluate the reactions of 33 common bean genotypes (23 landrace, 8 commercial, 1 susceptible standard and 1 resistant standard) to M. javanica, employing multivariate statistics to discriminate the ..

Epistasis in intra- and inter-gene pool crosses of the common bean
Authors: J.C. Borel1, M.A.P. Ramalho2 and A.F.B. Abreu3
Epistasis has been shown to have an important role in the genetic control of several quantitative traits in the common bean. This study aimed to investigate the occurrence of epistasis in intra- and inter-pool gene crosses of the common bean. Four elite lines adapted to Brazilian conditions were used as parents, two from the Andean gene pool (ESAL 686; BR.. Read More»

Snap bean recommendation based on different methods of phenotypic stability
Authors: C.D. Marinho G.A. Gravina L.C. Ara�ºjo S.N.C. Almeida A.T. Amaral J�ºnior R.F. Daher L.S.A. Gon�§alves
In order to recommend the best strains of snap beans from the Universidade Estadual do Norte Fluminense (UENF) breeding program, different methods of analysis of phenotypic stability were adopted to evaluate the performance of 14 lines (F9 and F10) of indeterminate growth habit, which were compared with 3 controls, namely, 2 commercial varieties (Feltrin ..

Potential of hypocotyl diameter in family selection aiming at plant architecture improvement of common bean
Authors: A.M.C. Oliveira, R.O. Batista, P.C.S. Carneiro, J.E.S. Carneiro and C.D. Cruz
Cultivars of common bean with more erect plant architecture and greater tolerance to degree of lodging are required by producers. Thus, to evaluate the potential of hypocotyl diameter (HD) in family selection for plant architecture improvement of common bean, the HDs of 32 F2 plants were measured in 3 distinct populations, and the characteristics related ..

Selection of common bean (Phaseolus vulgaris L.) genotypes using a genotype plus genotype x environment interaction biplot
Authors: A.M. Corr�ªa, P.E. Teodoro, M.C. Gon�§alves, A. Santos and F.E. Torres
Recently, the genotype plus genotype x environment interaction (GGE) biplot methodology has been used to investigate genotype x environment interactions in several crop species, but has not been applied to the common bean (Phaseolus vulgaris L.) crop in Brazil. The aim of this study was to identify common bean genotypes that exhibit high grain yield and s.. Read More»

Genetic progress resulting from forty-three years of breeding of the carioca common bean in Brazil
Authors: L.D. Barili, N.M. Vale, L.M. Moura, R.G. Paula, F.F. Silva and J.E.S. Carneiro
We aimed to evaluate 40 common bean cultivars recommended by various Brazilian research institutions between 1970 and 2013 and estimate the genetic progress obtained for grain yield and other agronomic traits. Additionally, we proposed a bi-segmented nonlinear regression model to infer the year in which breeding began to show significant gains in Brazil. .. Read More»

Effect of generations and environments in the analysis of a partial diallel to improve bean earliness
Authors: N.M. Vale, L.D. Barili, M.H. Souza, L.M.M. Moura, J.E.S. Carneiro, P.C. Carneiro and F.L. Silva
The objective of this study was to select genitors based on F1 and F2 generations, evaluated in different environments, to obtain segregating populations for the identification of strains showing improved earliness, yield, and carioca-type grains. Nine bean strains were crossed in a partial diallel scheme (4 x 5), in which group 1 included 4 strains with .. Read More»

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»

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»
