Heterosis for the improvement of yield in mungbean [Vigna radiata (L.) Wilczek]
Authors: P.A. Tantasawat, P. Khajudparn, T. Prajongjai and O. Poolsawat
Heterotic effects of mungbean hybrids from 25 crosses between parents differing in 9 agronomic and physiological traits were evaluated for various selected traits and seed yield. Significant heteroses were observed in most selected traits, except for the number of seeds per plant. When the heterosis of seed yield was evaluated in these hybrids, significan.. Read More»

Selection of strawberry cultivars with tolerance to Tetranychus urticae (Acari: Tetranychidae) and high yield under different managements
Authors: A.F. Costa, P.E. Teodoro, L.L. Bhering, M.J. Fornazier, J.S. Andrade, D.S. Martins and J.S. Zanuncio Junior
Tetranychus urticae Koch (Acari: Tetranychidae) is considered the main pest of strawberry. Several factors can favor its development, among them the genotype susceptibility and cropping system. The aims of this study were to evaluate the agronomic performance of strawberry cultivars under different managements and to identify .. Read More»

Use of molecular markers in reciprocal recurrent selection of maize increases heterosis effects
Authors: A.P.C.G. Berilli, M.G. Pereira, L.S.A. Gon�§alves, K.S. da Cunha, H.C.C. Ramos, G.A. Souza Filho and A.T. do Amaral J�ºnior
We examined the effect of incorporation of molecular markers on variability between and within populations in order to maximize heterotic effects and longevity of a maize reciprocal recurrent selection program. Molecular variability was quantified by inter-simple sequence repeat (ISSR) markers between and within the maize popu.. Read More»

Selection index using the graphical area applied to sugarcane breeding
Authors: L.A. Silva, R.T. Resende, R.A.D.C. Ferreira, G.N. Silv, V. Kist, M.H.P. Barbosa, M. Nascimento and L.L. Bhering
This study aimed to develop a multivariate selection index based on the graphical area of a polygon formed by standardized values, also known as radar chart. This methodology may be used to assist selection of superior genotypes in sugarcane breeding programs. Seven technological traits in 37 sugarcane genotypes were evaluated. An area index (AI) was cons.. Read More»

Biometric analysis of arabica coffee grown in low potassium nutrient solution under greenhouse conditions
Authors: W.M. Moura, Y.J.B. Soares, A.T. Amaral J�ºnior, G.A. Gravina, L.D. Barili and H.D. Vieira
Genetic parameters and associations between morpho-agronomic traits and nutritional efficiencies of arabica coffee cultivars were estimated to identify promising traits to assist in the selection of coffee genotypes efficient in potassium use, under limiting conditions of this nutrient. The experiment was conducted in a greenhouse with 20 arabica coffee c.. Read More»

Selecting elephant grass families and progenies to produce bioenergy through mixed models (REML/BLUP)
Authors: E.V. Rodrigues, R.F. Daher, A. dos Santos, M. Vivas, J.C. Machado, G. do A. Gravina, Y.P. de Souza, A.K. Vidal, A. dos S. Rocha and R.S. Freitas
Brazil has great potential to produce bioenergy since it is located in a tropical region that receives high incidence of solar energy and presents favorable climatic conditions for such purpose. However, the use of bioenergy in the country is below its productivity potential. The aim of the current study was to select full-sib.. Read More»

Identification of QTLs of resistance to white mold in common bean from multiple markers by using Bayesian analysis
Authors: L.A.C. Lara, J.B. Santos, M. Balestre, I.A. Lima, A.K.A. Pamplona,J.S. Veloso and P.H. Silva
In this study, we identified simple sequence repeat, amplified fragment length polymorphism, and sequence-related amplified polymorphism markers linked to quantitative trait loci (QTLs) for resistance to white mold disease in common bean progenies derived from a cross between lines CNFC 9506 and RP-2, evaluated using the oxalic acid test and usi..

Implications of the progeny x environment interaction in selection index involving characteristics of the common bean
Authors: L.K. Lima M.A.P. Ramalho A.F.B. Abreu
Breeders normally select simultaneously for several traits in various environments. We investigated the effects of the progeny x environment interaction on success in selection for several traits. The population used was obtained from a cross between the CVIII-85-11 line, which has a semi-erect to prostrate plant architecture and a cream with brown streak.. Read More»

Experimental strategies in performing value for cultivation and use experiments for the tobacco crop II: dimension of the experimental network
Authors: C.E. Pulcinelli, A.T. Bruzi, F.H.R.B. Toledo and M.A.P. Ramalho
In this study, we aimed to establish strategies for value for cultivation and use (VCU) experiments for the tobacco crop in the southern region of Brazil with respect to the number of environments used to assess tobacco lines. Trials of the Virginia (18 sites) and Burley (17 sites) varietal groups were conducted in the three s.. Read More»

Soybean rust resistance sources and inheritance in the common bean (Phaseolus vulgaris L.)
Authors: T.L.P.O. Souza, S.N. Dessaune, M.A. Moreira and E.G. Barros
Soybean rust (SBR), caused by the fungus Phakopsora pachyrhizi, has been reported in common bean (Phaseolus vulgaris L.) cultivars and elite lines that were infected under controlled and natural field conditions in South Africa, the United States, Argentina, and Brazil.
