Genotype × environment interaction (GEI) is an important aspect of both plant breeding and the successful introduction new cultivars. In present study, additive main effects multiplicative interactions (AMMI) genotype (G) (E) (GGE) biplot analyses were used to identify stable genotypes dissect GEI in Plantago. total, 10 managed field trials considered as environments analyze thirty belonging eight Plantago species. Genotypes evaluated a drought stress treatment normal irrigation conditions at two locations Shiraz (Bajgah) for three years (2013-2014- 2015) Kooshkak (Marvdasht, Fars, Iran) (2014–2015). Three traits, seed yield mucilage content, measured each experimental site natural habitats. AMMI2 identified from several species with higher stability other content yield. P. lanceolata (G26), officinalis (G10), ovata (G14), ampleexcaulis (G11) major (G4) had For yield, G21, G18 G20 (P. psyllium), G1, G2 G4 major), G9 G10 officinalis) stable. G13 ovata), G5 G6 major) G30 lagopus) content. No one was found have high levels more than trait but some exhibiting performance. Based on variation, GGE analysis representative environments, good discriminating ability. The identification should assist
