“…However, performance as a selection criterion is not the only empirical assessment of the combination of past events, and does not provide information about metabolic processes that increase the benefit. On the other hand, direct selection for performance may include restrictions such as limitation of genetic variation (Fasahat et al, 2014;Fasahat et al, 2020). In this study, a wide range in root yield was present for the given environments.…”

“…In this study, a wide range in root yield was present for the given environments. In previous studies, it has been shown that the climate has a strong influence on sugar beet growth, yield, and quality (Kenter et al, 2006;Hoffmann et al, 2009;Fasahat et al, 2020). For example, in a study by Hoffmann et al (2009), nine sugar beet genotypes were evaluated in 52 environments across European countries for root yield and quality.…”

SummaryThe evaluation of sugar beet genotypes under different climate conditions is a principal goal of breeding programs. In most studies, environment has a high influence on the qualitative and quantitative traits of sugar beet. Therefore, data collected from different environments may contribute to more accurate genotype selection. In this study, the effect of different environments on sugar beet genotypes’ performance was evaluated using a meta-analysis method based on Hedges’ technique. Data were collected from 149 trials conducted in twelve regions in Iran over 15 years (2003–18). For all trials, the value of the traits was weighted, and subsequently the effect size, reaction ratio and confidence interval were estimated. Among the studied environments, Khoy had a positive effect on root yield, sugar content, sugar yield and white sugar yield. As could be expected, the effect of environment on final yield formation was high, so that the Shiraz environment had a negative effect on root yield and sugar yield. Overall, the ranking of environments based on the meta-analysis results was quite different from that obtained by comparison of mean results.
