The promotion and development of winter-sown sugar beet is one of the significant approaches for using seasonal rainfalls and saving irrigation water for its production. For this purpose, the present study was conducted to study the of genotype × environment interaction effect on white sugar yield of 11 winter season short-season sugar beet cultivars, and selection of superior cultivars in three regions of Moghan,(2019, 2020 and 2021) Torbat-e-Jam (2020 and-2021), and Joveyn (2020) using randomized complete block design with four replications. Combined analysis of variance showed that the environment, genotype and genotype × environment interaction had significant (P ≤ 0. 01) effect on white sugar yield. The GGE biplot method revealed that the first and second main components explained 83.64% of the total variation in white sugar yield. Based on the GGE biplot method, in Moghan 2021, cv. SVZB2019 and Dravos, and in Moghan 2019 and 2020, in Torbat-e-Jam 2020 and 2021 and in Joveyn 2020, cv. FDIR19B3021, cv. FDIR19B4028 and cv. SVZA2019 identified as the best cultivars with high white sugar yield and yield stability, respectively. In general, it was concluded that the environment played a significant role in phenotypic expression of the white sugar yield in the winter-sown short season sugar beet cultivars. Therefore, it would be necessary to select and release sugar beet cultivars adapted to climatic and agronomic conditions for winter sowing in target environments.
