Graphical analysis to determine the stability and adaptability of yield characteristics of dwarf cashew trees

The cashew culture provides jobs and boosts the economy of Northeast region is therefore great socioeconomic importance. In genetic improvement programs, existence an interaction between genotypes environments has been observed, making studies adaptability stability essential for effective selection. Thus, objective was to study performance early dwarf clones using GGE Biplot in three agricultural years (2016–2018). experimental design randomized blocks with 25 treatments (clones) replications. plot consisted four plants spaced 8 × m apart. variables evaluated were nut yield throughout harvest (PRC), average weight (PMC), percentage nuts pierced (PCF). most characterized as ideotypes T25, T14, T7, T8, T2, T10, T15, T22 PRC; T12, T1, T16 PMC; T5, T24, T21, T8 PCF, coincidence PC PCF. Clones values above general average, emphasis on stability, T14 T2 T16, T5 test characteristics, that is, those environmental factors all years, 2016 PRC 2018 no year every more discriminating exception PRC.
