Abstract

Sugar beet is regarded as a main source of sugar supply alongside sugarcane. To evaluate new promising hybrids in terms of stability and adaptability, six distinct environments were used to sow 15 different sugar beet genotypes. The results of the combined analysis of variance showed that genotype, environment, and their interaction had a significant impact on root yield and white sugar yield. Among 15 genotypes, using AMMI biplot analysis, G5 and G14 were distinguished as adaptive and high-yielding genotypes for root yield, and G6 for white sugar yield. The interaction between the first two principal components of the AMMI 2 biplot model explained 72.3% of the variation resulting from the G + G × E interaction for root yield and 75.2% for white sugar yield. G5 stands out as the genotype with the greatest stability and yield efficiency. The GGE biplot revealed environment 3 as the ideal environment. Genotypes G7, G6 and G5 were selected as the superior stable genotypes with respect to white sugar yield based on the WAASB stability index, while G5 was determined as the most stable genotype by MSTI. Using the GGE biplot, G5’s high white sugar yield and stability within diverse environments made it the optimum genotype.
