Targeted crossing are conducted annually at plant production institutes to increase genetic diversity. One of the goals of the institutes involved in sugar beet breeding is to produce new varieties, compare products, and conduct multi-location trials. The Sugar Beet Seed Institute, as the only institute active in the production and supply of sugar beet varieties, conducts targeted crossing between sugar beet varieties each year to produce different cultivars. The application of breeding methods has led to a continuous increase in the yield of sugar beet varieties, thereby helping to meet the global food and biomass needs. The aim of this study was to evaluate the improvement of white sugar yield of sugar beet genotypes using meta-analysis. For this purpose, experiments carried out in Karaj region during 2003-18 were evaluated. The required condition for data collection was the number of replicates and controls in each experiment. Results showed that in 2006 and 2011, white sugar yield increased by 16% and 6%, respectively.
