Mehrzad Ahmadi Seed and Plant Improvement Institute, Agricultural Research, Education and Extension Organization (AREEO), Karaj, Iran Journal Article 2022 09 26 This study was conducted to obtain high yielding adaptive lines of PachBaghela (<em>Phaseolus vulgaris</em>) in Guilan region, using randomized complete block design with three replications in spring season in three locations of Guilan province (Lahijan, Rasht, Shanderman) in 2016 and 2018 cropping seasons. Nine lines were evaluated along with local landrace. The results of combined analysis of variance of fresh pod yield in three regions during two years showed that the effect of genotype and the interaction of genotype × location × year were significant. Also, the results showed that the lines had a significant difference in fresh pod yield. The comparison of the average yield of fresh pods in the studied regions during two years showed that the G9 line had the highest yield and the lowest yield was related to the local landrace in the spring cultivation. Analyzing the stability of fresh pod yield by the non-parametric rank method showed that G9 and G8 lines were the most stable lines. Also, based on the GGE biplot, G9 and G8 lines were selected as the best lines with high yield and compatibility.
