Abstract
The present work aims to analyze the genetic divergence with and without the use of Azospirillumbrasilense in maize cultivars. The experiment was carried out at the Federal University of Tocantins (UFT),Gurupi Campus. The design used was randomized blocks, with ten treatments and three replications, wherethe treatments are represented by ten maize cultivars. The variables were measured when the plant reachedR6 stage. For the study of genetic divergence, the following variables were analyzed: The number of grainsper row (NGPF), number of rows per spike (NFE), plant height (AP), the height of the spike (AE), moisture(UMID), grain yield (kg). The Tocher method was used to verify similar groups; for the verification of geneticdistance, there was the foundation through the generalized distance of Mahalanobis (Dò) and Singhââ¬â¢scriterion for quantifying the contribution of the variables evaluated. The characteristics of grain yield andnumber of grains per row were the ones that most contributed to the genetic divergence for treatments withAzospirillum and without Azospirillum. The crosses between cultivars aiming at promising combinations toobtain strains are BM3051 X CATIVERDE with Azospirillum and BM3051 X CATIVERDE withoutAzospirillum.
