PRODUTIVIDADE E ESTABILIDADE DE HÍBRIDOS DE MILHO EM TRÊS MUNICIPIOS DO CENTRO – NORTE GOIANO

Abstract

This research aimed to evaluate the agronomic and productive characteristics of corn hybrids in three municipalities in Goiás. The experiment was carried out in commercial areas of producers. The experimental design used was randomized blocks in an 18x3 factorial scheme (18 hybrids and 3 locals) with four replications. The locations were in Campinorte, Ceres and Itapaci. Each plot consisted of two five-meter lines. The productivity (kg ha-1) and stability of hybrids were evaluated using the GGE Biplot model. The data were subjected to analysis of variance and compared using the Skott-Knott test at a 5% significance level. In Campinorte the best hybrids were MG711 PW and P30F53 Leptra whose productivity was 9596.0 and 9594.4 kg ha-1, respectively. In the municipality of Itapaci, the hybrid that showed the highest productivity was MG711 PW, whose productivity reached 12122.0 kg ha-1 . The performance of hybrids in the municipality of Ceres was the worst among all locations, with emphasis on the hybrids AG8061 PRO2 and AS1633 PRO2, whose productivity was 4479.0 and 4438.8 kg ha-1 ,respectively. The MG711 PW hybrid behaves with greater stability in the municipalities of Campinorte and Itapaci. In the municipality of Ceres, hybrids had the worst performance among the three locations.
