Evaluation and comparison of quantitative and qualitative characteristics of commercial sugar beet cultivars in the western region of the country (Kermanshah and Lorestan)

The present study was conducted with the aim of evaluating and grouping new domestic and foreign sugar beet cultivars for quantitative and qualitative characteristics in the western region of the country.

In these experiments, 12 domestic and foreign commercial cultivars were evaluated in a randomized complete block design with three replications in the two regions of Kermanshah and Lorestan.

The results showed that the Rivolta variety in the Kermanshah region, and the Perfekta variety in the Lorestan environment showed the highest root yield, sugar yield and with sugar yield. Also, in the Kermanshah environment, the cultivars Rivolta and Anaconda were the closest cultivars to the ideal cultivar, and in the Lorestan environment, the cultivars Perfekta and Cadmus were the closest to the ideal cultivar respectively. Based on the results of cluster analysis, cultivars were classified into three groups in Kermanshah and five groups in Lorestan. So, in the Kermanshah area, three cultivars Anaconda, Perfekta, and Rivolta, and in Lorestan three cultivars of Anaconda, Gecko, and Perfekta were placed in a cluster that had the best quantitative and qualitative characteristics. In factor analysis, two factors were identified in both environments, which explained 77.85% in Kermanshah and 88.11% of data changes in Lorestan conditions.

In this study, two commercial cultivars, Anaconda and Perfekta, had the best quantitative and qualitative characteristics in both environments. Cultivation of these two cultivars can improve the potential of sugar production in the western region of the country.
