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»

Genetic divergence in the common bean (Phaseolus vulgaris L.) in the Cerrado-Pantanal ecotone
Authors: F.A. da Silva, A.M. Corr�?ªa, P.E. Teodoro, K.V. Lopes, C.C.G. Corr�?ªa
Evaluating genetic diversity among genotypes is important for providing parameters for the identification of superior genotypes, because the choice of parents that form segregating populations is crucial. Our objectives were to i) evaluate agronomic performance; ii) compare clustering methods; iii) ascertain the relative contr.. Read More»

Selection of common bean genotypes for the Cerrado/Pantanal ecotone via mixed models and multivariate analysis
Authors: A.M. Corr�?ªa, M.I.S. Moraes, H.K.A. de Abreu, T. Sharon, C.L.P. de Melo, M.A. Ito, P.E. Teodoro and L.L. Bhering
The common bean, Phaseolus vulgaris, is predominantly grown on small farms and lacks accurate genotype recommendations for specific micro-regions in Brazil. This contributes to a low national average yield. The aim of this study was to use the methods of the harmonic mean of the relative performance of genetic values (HMRPGV) .. Read More»

Characterization of the dry bean polygalacturonase-inhibiting protein (PGIP) gene family during Sclerotinia sclerotiorum (Sclerotiniaceae) infection
Authors: M.B. Oliveira1, L.B. Nascimento1, M.L. Junior2 and S. Petrofeza1
Polygalacturonase-inhibiting proteins are leucine-rich repeat proteins that inhibit fungal endopolygalacturonases. The interaction of polygalacturonase-inhibiting protein with endopolygalacturonases limits the destructive potential of endopolygalacturonases and may trigger plant defense responses induced by oligogalacturonides..

Genetic potential of black bean genotypes with predictable behaviors in multienvironment trials
Authors: 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) me..

Genetic control of the resistance of common beans to white mold using the reaction to oxalic acid
Authors: R.P. Antonio, J.B. Santos, T.P. Souza and F.F. Carneiro
The use of genetically resistant cultivars is the best method to reduce losses caused by white mold (Sclerotinia sclerotiorum (Lib.) de Bary). As the best known resistance sources are not adapted, the genetic control of white mold in the common bean must be understood to guide breeding more efficiently. The objective of the pr.. Read More»

White mold resistance-associated quantitative trait loci in the Jalo x Small White common bean population
Authors: D.A. Souza, M. Balestre, A.K.A. Pamplona, M.E. Leite, J.A. Dias and J.B. Santos
We aimed to identify simple sequence repeat (SSR) markers linked to quantitative trait loci (QTLs) associated with white mold resistance in a segregating population derived from a cross between common bean cultivars Jalo and Small White, in the Southern State of Minas Gerais. Parents were crossed to obtain the F2 generation of 190 plants. From these, F2:3.. 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»
