Conteúdo: 	The maize population 'Elite Synthetic NT' has been selected with the objective of improvement its yield potential in soils with low nitrogen (N) availability. During the 1994/95 season, 144 half-sib families showing good male-female flowering synchrony were evaluated with and without N fertilizer at Sete Lagoas, MG. The experimental design utilized was a 12 x 12 lattice, with 5 m plots. The open-pollinated variety 'BR 106', selected in soils with high fertility, was used as a between block check. Mean ear weight for the selected families in N+ and N-environmental averaged 4,511 kg/ha and 3,327 kg/ha, respectively. Yield reduction between environmental averaged 27.14% for the selected families and 65.8% for BR 106. The results indicate that selection inN-environments is an efficient approach for developing genotypes with better performance in soils with low nitrogen content.
