Abstract

This study evaluated the use of AMMI methodology for agronomic performance data in peanut lines across 11 experiments carried out between 2015 and 2020 growing seasons in the Stateof São Paulo. Each experiment was planted in a ramdomized blocks design with3 replications in plots of two rows, 5 m. long, with 100 seeds/rowand 0,90 m. Between rows. Individual andpooled analises of variance were performed for yield, weight of 200 kernels and shelling percentage. Breeding lines 10677, 10678 and 10719 showed general adaptability and stability over the environments, line 10677 and 10678 had specific stability in unfavourable environments. Line 10719 showed better performance in favourable environments. All lines showed yields higher than the control cultivars IAC OL3 and IAC OL5.
