R. de A. aStability and adaptability of seedcotton yields of upland cotton genotypes in the state of Minas Gerais, Brazil. c2002 aSeedcotton yield of Gossypium hirsutum L. data from the regional cotton variety trials of the EPAMIG breeding program from 1990 to 1999 were analyzed with the objectives of estimating both the magnitude of genotype by environment interactions and the genotypes adaptability and stability according to the methods proposed by Eberthart and Russell, Lin and Binns and Annicchiarico; and selecting advanced lines to compose the final trials of the program. Four groups of genotypes and environments were assembled and analyzed. For the first one, significant genotype x year and genotype x location x year interactions were detected. The most stable genotypes were MG-864492 and IAC 20. Significant second-order interactions were estimated for the three remaining groups studied. In the second group the most stable strains were MG-863192 (according to Eberhart and Russell method) and MG-863579 (according to Lin & Binn's and Annicchiaric's methods). For the third genotype-environment group, the most stable genotype under all methods was MG-864133. The cultivar EPAMIG 5 Precoce-1, in the fourth group, presented stable performance also under the three methodologies tested. acotton agenotype aAlgodão aGossypium Hirsutum aAdaptabilidade aAdaptability aEnvironment interactions aEstabilidade aStability1 aPENNA, J.
