Seedcotton 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 genotype adaptability and stability according to the methods proposed by Eberhart 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 Annicchiarico’ 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. |
