ABSTRACT - The objective of this work was to evaluate the potential of allohexaploid pearl millet x elephantgrass (HGL) population for a recurrent selection program through open-pollinated progenies. Seventy-eight progenies, one representative sample of the population, and two commercial cultivars, Pioneiro and Paraíso, were evaluated in a 9x9 triple lattice design, in two sites. Plant height and dry matter yield were evaluated in three and four cuts, respectively. For plant height, the 17 best progenies were similar to both commercial controls, while for dry matter yield they were higher than 'Paraíso' and lower than 'Pioneiro'. The correlation between progenies and cuts indicated that the fourth cut represents the mean of all cuts, and the possibility of using early selection. Heritability estimates considering cuts and sites were 56.9% for plant height and 58.8% for dry matter yield, and the expected response to selection was 23.4% for dry matter yield and 18.1% for plant height. These results demonstrate the promising HGL population potential for a recurrent selection program. RESUMO ? O objetivo deste trabalho foi avaliar o potencial para programa de seleção recorrente, em uma população alohexaplóide de milheto x capim-elefante (HGL), por meio de progênies de polinização aberta. Setenta e oito progênies, uma testemunha representativa da população e duas cultivares comerciais, a Pioneiro e a Paraíso, foram avaliadas no delineamento látice triplo 9x9, em dois locais. Os caracteres altura de plantas e produtividade de matéria seca foram avaliados por três e quatro cortes, respectivamente. Quanto à altura de plantas, a média das 17 melhores progênies foi similar às das testemunhas comerciais e, quanto à produtividade de matéria seca, foi maior do que a da 'Paraíso' e menor do que a da 'Pioneiro'. A correlação entre progênies e colheitas mostrou que a quarta colheita representa a média de todas as colheitas e a possibilidade de seleção precoce. As estimativas de herdabilidade na média das colheitas e locais foram de 56,9% para altura de plantas e de 58,8% para produtividade de matéria seca, e a reposta esperada com a seleção foi de 23,4% para produtividade de matéria seca e 18,1% para altura de plantas.

Background: The production and commercial release of Genetically Modified Organisms (GMOs) are currently the focus of important discussions. In order to guarantee the quality and reliability of their trials, companies and institutions working on this subject mustadopt new approaches on management, organization and recording of laboratory conditions where field studies are performed. Computational systems for management and storage of laboratory data known as Laboratory Information Management Systems (LIMS) are essential tools to achieve this. Results: In this work, we have used the SIGLa system – a workflow based LIMS as a framework to develop the FluxTransgenics system for a GMOs laboratory of Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Maize and Sorghum (Sete Lagoas, MG - Brazil). A workflow representing all stages of the transgenic maize plants generation has been developed and uploaded in FluxTransgenics. This workflow models the activities involved in maize and sorghum transformation using the Agrobacterium tumefaciens method. By uploading this workflow in the SIGLa system we have created Fluxtransgenics, a complete LIMS for managing plant transformation data. Conclusions:FluxTransgenics presents a solution for the management of the data produced by a laboratory of genetically modified plants that is efficient and supports different kinds of information. Its adoption will contribute to guarantee the quality of activities and products in the process of transgenic production and enforce the use of Good Laboratory Practices (GLP).The adoption of the transformation protocol associated to the use of FluxTransgenics has made it possible to increase productivity by at least 300%, increasing the efficiency of the experiments from between 0.5 and 1 percent to about3%. This has been achieved by an increase in the number of experiments performed and a more accurate choice of parameters, all of which have been made possible because it became easier to identify which were the most promising next steps of the experiments. The FluxTransgenics system is available for use by other laboratories, and the workflows that have been developed can be adapted to other contexts.
