Potencial genético da popula？？o de milho UFV 7 para o melhoramento em Minas Gerais

the objective was to assess the genetic potential of maize population ufv 7 for breeding in minas gerais, brazil. three experiments were installed with the maize population ufv 7 in the three regions of minas gerais, in the harvest of 2006/2007. there was genotype x environment interaction for all characters. it was observed genetic variability for grain yield, plant height and ear height in maize population ufv 7, in the three regions. the southeast region was where the maize population ufv 7 had the highest parameters. the population ufv 7 presented high grain yield, 9 112kg ha-1 in the southeast, average grain yield, 6 510kg ha-1 in the west and low, 4 572kg ha-1 in the central region. heritability estimate and cvg / cve for grain yield were higher than 60% and 1.00, respectively. grain yield had significant and positive genetic correlation with plant height and ear height, in western and central, and the prolificacy in central and southeast. for maize population ufv 7 it was conclude that it has potential for extraction of lines in the central region; it has the potential for immediate use in the southeast and for new cycles selection in the western region of minas gerais. the selection for pg provides an indirect increase in plant height and ear height, in the west and central.
