The present study was conducted involving 25 genotypes of French bean evaluated across three locations of Punjab viz. PAU, Ludhiana, USF, Usman, Tarn Taran and KVK, Kheri Sangrur during two crop seasons 2017 and 2018 with the objective to identify stable genotypes and genotype x environment interaction using GGE biplot analysis for green pod yield per plant and related traits. All the environments were positively correlated (an acute angle) which suggested that these environments were similar for discriminating genotypes. The environment E3 (KVK, Sangrur 2017) was most representative for green pod yield per plant. The genotype Arka Suvidha recorded highest green pod yield per plant followed by Arka Anoop, Falguni, Arka Sharath and FB-3-16, while the genotype FB-3-14 recorded lowest green pod yield per plant. The genotype Contender was highly unstable because its yield varied in different environments. Based on this study, the genotypes Arka Suvidha, Arka Anoop, Arka Sharath and Falguni can be recommended for commercial cultivation.
