Evaluation of New Autumn Sown Sugar Beet Cultivars for Quantitative and ‎Qualitative Traits in Khuzestan Province

The present study has been conducted to compare new sugar beet cultivars for quantitative and qualitative traits in autumn sown condition as randomized complete block design at Safiabad agricultural and natural resources research and education center in 2017-2018. It has included 22 new sugar beet cultivar, investigated in three replications. Measured traits included number of leaf in plant, root yield, sugar content, white sugar content, white sugar yield, extraction coefficient of sugar, sodium, potassium, α-amino nitrogen, molasses sugar, and alkaloid ratio. The results show that all the measured traits in the cultivars have differed significantly. Highest root yield and white sugar yield are obtained from Callas and Honey cultivars with 125 and 113 ton/ha root yield and 13.5 and 13.6 ton/ha white sugar yield, respectively. Highest sugar and white sugar content with 15.75% and 13.63% are obtained from Sporta. Highest and lowest extraction coefficient of sugar are related to Sporta (86.5%) and Sharif (72.6%), respectively. The range of sodium, potassium, and α-amino nitrogen content has been from 1.54 to 4.26, 2.25 to 3.95, and 1.78 to 3.22 mEq, respectively. In total, to achieve maximum income for the farmer it is recommended that Callas and Honey cultivars or other cultivars that are in the same group with these cultivars should be used to obtain maximum root and sugar yield.
