This work had the objective to evaluate the performance of soybean lines, come from the Program of Genetic Improvement of soybean of the Federal University of Uberlândia, in regional tests of evaluation of lines in the cities of Goiatuba, Rio Verde, Bela Vista, Campo Alegre and Porangatu, in the State of Goiás. 27 lines of delayed cycle had been evaluated and having as witnesses to cultivate them M-Soy 866, Guarantee, M-Soy 8800, Chapadões and M-Soy 8411, sown in the agricultural year of 2004/2005. The experimental design was of randormized blocks, with 3 replications. 32 genotypes in each one of the five places had been tested. The parcel was similar in all the experiments, being formed by four rows of 5 meters of length, spaced 0,45m between rows. The evaluated character it was: productivity of grains (PG). The methodologies that quantify the used adaptability and/or fenotype satability had been simple linear regression of Eberhart and Russell; bissegmentada lenear regression of Cruz; Torres and Vencovsky. The interpretation that better took care of to the objectives of the improvement was of the methodology of Eberhart and the Russell, detaching lines 9, for congregating good productivity of grains, adaptability and stability in the test places.
