Abstract

The production of maize to feed animals follows two aptitudes in relation to production of feed in semi-arid regions: grains and silage. However, the high Sergipano sertão is a region commonly with low water availability and food shortages. Thus, obtaining genetic variability from specific crosses can assist in the selection of maize genotypes with forage potential. The objective was to characterize commercial and experimental maize genotypes to obtain crossing blocks with forage potential evaluated in semi-arid region. The experiment was carried out at the Embrapa Experimental Farm - Semi-arid, the square latice lattice design was made in incomplete block structure with dimension 6x6 with two replications and 36 treatments. The variables plant height, stem diameter, plot weight, fresh mass, dry mass and forage mass were analyzed. The data were submitted to phenotypic correlation analysis, relative contribution of each variable and genetic divergence. There were indications of the formation of at least three intersection blocks: block I, suitable for fresh mass; block II, with suitability of parcel weight and forage mass; block III, suitable for plant height, stem diameter and dry mass.
