ABSTRACT Selection indexes represent the real efforts of a breeding program to obtain genetic gains for various significant traits simultaneously. As such, this study selected superior F5 lines by combined selection for fruit quality using an index based on predicted genotypic values via residual or restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) methodology weighted by agronomic weights. To do so, 97 F5 papaya lines obtained by the single seed descent method, resulting from the biparental cross between the genotypes JS-12 and Sekati, were evaluated for the main traits related to fruit quality. Results of the analysis of deviance and the genetic parameters indicated that there was genetic variability, indicating possible success in the selection process. Based on the selection index, 29 lines were selected as superior for fruit quality with ‘Formosa’ pattern. The strategy of the selection index combining BLUPs of multiple traits of interest associated with agronomic weights allows maximizing genetic progress while discarding less-promising genotypes.

Este artigo apresenta os percursos teórico-metodológicos e os resultados de um estudo sobre a avaliação de impacto do Programa Primeira Escola da Rede Municipal de Ensino de Belo Horizonte sobre as famílias das crianças que se encontravam matriculadas na Unidade Municipal de Educação Infantil - UMEI - Carlos Prates - Danielle Mitterrand, no ano de 2004. A pesquisa buscou dados sobre a situação das crianças e suas famílias no ano de 2004, quando a UMEI foi inaugurada, e em 2008, quando foi realizado o trabalho de campo. Os dados empíricos possibilitaram avaliar o impacto da UMEI na renda e no orçamento familiar, nos hábitos de higiene, na saúde e no desenvolvimento cognitivo das crianças.

This paper presents the theoretical-methodological paths and results of the study on assessment of the impact of the First School Program of Belo Horizonte's Municipal Education Network over the families of children that were enrolled in the Unidade Municipal de Educação Infantil [Municipal Unit of Early Childhood Education] - UMEI - Carlos Prates - Danielle Mitterrand in 2004. The survey collected data on the situation of children and their families in 2004, when UMEI was inaugurated, and in 2008, when the fieldwork was carried out. The empirical data made it possible to assess the impact of UMEI in the children's family income and budget, hygiene habits, health, and cognitive development.

Este artículo presenta la trayectoria teórico-metodológica y los resultados del estudio respecto a la evaluación del impacto del Programa Primera Escuela de la Red Municipal de Enseñanza de Belo Horizonte hacia las familias de los niños que estabam matriculados en la Unidad Municipal de Educación Infantil - UMEI - Carlos prates - Danielle Miterrand, en el año 2004. La investigación buscó datos sobre la situación de los niños y sus famílias en el año 2004, cuando se puso en funcionamiento la UMEI y, también, 2008, cuando fue realizada la investigación de campo. Los datos empíricos posibilitaron que se evaluara el impacto de la UMEI en la renta y en el presupuesto familiar, en los hábitos de higiene, en la salud y en el desarrollo cognitivo de los niños.
