Abstract

Sorghum is a crop of great importance for double cropping, in the Brazilian Central-West region. Within this region, in the Southwestern Goiás State, a research was conducted to select sorghum (Sorghum bicolor (L.) Moench) cultivars, in the municipalities of Montividiu, Rio Verde, and Santa Helena de Goiás. A randomized blocks design, with four replications, was used. The grain sorghum cultivars tested were: BR 304, 741, 822, Catuy, and the experimental hybrid V 00069. The cultivars were sown on March 5, 2005. The evaluated characteristics were: yield, weight of thousand grains, plant height, and flowering and maturation dates. The results showed the interaction genotype x environment for all evaluated characteristics. The region of Montividiu presented better potential for sorghum grain production. Early flowering and harvest allowed higher grain yields.
