Evaluation of qualitative and quantitative traits of autumn cultivation sugar beet varieties in Dezful region during two years

In order to evaluate quantitative and qualitative properties of three sugar beet cultivars (HI1059, Palma and Merac), an experiment was conducted as randomized complete block design with four replications at Agricultural Research Center Safiabad in 2011-2012 and 2012-2013 growing seasons. The analysis of simple variance examined showed that in first year among varieties for the bolting, sugar content, alkalinity and white sugar content traits there significant difference, whereas in the second year of potassium, molasses sugar and white sugar content traits were significant differences. The result of the compound analysis in both years the effect year on bolting, sodium, potassium, amino-nitrogen, molasses sugar, white sugar content and extraction coefficient of sugar traits was significant. The result mean bolting (%) in the first year showed that in the HI1059 and Palma cultivars were 32.6% and 51.4%, respectively and in cultivar Merac, did not bolting happen, Whereas in the second year due to the weather moderation and absence of long cold any of the cultivars did not bolt. HI1059 cultivar of the most traits was higher than other cultivars. Depending on the climatic conditions experiment and the cultivation of sugar beet cultivar, there was differences in the number of plants bolting and the degree of their impact on formation and sugar molasses.
