Genetic analysis of yield component traits in cowpea [Vigna unguiculata (L.) Walp.]. Author(s): SANTOS, S. P. dos; ARAUJO, M. dos S.; ARAGAO, W. F. L. de; SILVA, K. J. D. e; ROCHA, M. de M. We investigated the genetic control of the three yield components in cowpea: number of grains per pod, pod length and grain size, in a biparental cross. Genetic parameters were estimated in generation... ... Repository: BDPA Publication year: 2024
Estimates for genetic variance components in reciprocal recurrent selection in populations derived from maize single-cross hybrids. Author(s): REIS, M. C. dos; PÁDUA, J. M. V.; ABREU, G. B.; GUEDES, F. L.; BALBI, R. V.; SOUZA, J. C. de This study was carried out to obtain the estimates of genetic variance and covariance components related to intra- and interpopulation in the original populations (C0) and in the third cycle (C3) of r... ...

Estimation of (co)variance components and genetic parameters for weights of red-winged tinamou using random regression models. Author(s): THOLON, P.; QUEIROZ, S. A. The objective of this work was to determine genetic parameters for body weight of tinamou in captivity. It was used random regression models in analyses of data by considering the direct additive gene... ... Repository: BDPA Publication year: 2011
Genetics components of rice root architecture and carbon isotopic fractionation parameters: a tracer for breeding in a water saving irrigation management. Author(s): BRITO, G. G. de; CONCENÇO, G.; COSTA, V. E.; FAGUNDES, P. R. R.; SILVA FILHO, J. L. da; PARFITT, J. M. B.; MAGALHAES JUNIOR, A. M. de; SILVA, G. T.; JARDIM, T. M.; LUCCAS, N. F.; SCIVITTARO, W. B. Phenotyping is the major bottleneck in the effort to develop varieties of rice (Oryza sativa L) suitable for grow under a water saving irrigation management, such as alternate wetting and drying irrig... ...

Genotypic values and genetic correlations for components and oil content of bunch of hybrids between caiaué and dendê. Author(s): FREITAS, A. F. de; LOPES, R.; CUNHA, R. N. V. da; PINA, A. J. de A.; RESENDE, M. D. V. de; GOMES JUNIOR, R. A. A hibridação interespecífica entre caiaué e dendê (HIE OxG) é explorada no melhoramento genético para atender a demanda de cultivares resistentes ao amarelecimento fatal (AF), maior problema fitossani... ...

Effective population size and genetic gain expected in a population of Coffea canephora. Author(s): MISTRO, J. C.; RESENDE, M. D. V. de; FAZUOLI, L. C.; VENCOVSKY, R. This work aimed to study the effective population size and genetic gain in a population of robusta coffee (Coffea canephora Pierre) and verify the possibility of using recurrent selection. The experim... ... Repository: BDPA Publication year: 2019
Genetic parameters for test day milk yields of first lactation Holstein cows by random regression models. Author(s): MELO, C. M. R. de; PACKER, I. U.; COSTA, C. N.; MACHADO, P. F. Covariance components for test day milk yield using 263 390 first lactation records of 32 448 Holstein cows were estimated using random regression animal models by restricted maximum likelihood. Three... ... Repository: BDPA Publication year: 2007
