ارزیابی هیبریدهای چغندرقند مقاوم به ریزومانیا در مناطق آلوده به بیماری آذربایجان غربی

Rhizomania is one of the most destructive disease of sugar beet which leads to severe losses in root yield and sugar content. These disease could be effectively controlled by using disease resistant varieties. In this research, 19 hybrids sugar beet varieties and 6 controls were evaluated in a randomized complete block design with 4 replicates in naturally infected locations (Oahnaviye) in 2012. In each experiment, yield and quality characteristics were measured in addition to disease resistance assessment. After data analysis and comparison of sugar yield and resistance, the varieties suitable for the location were identified. The hybrid (7112 * KWS) * 88022 showed significantly higher root yield (70.49) and sugar yield (11.52) t/ha than the mean of resistant checks. Thus this hybrid could be recommended for cultivation in the above-mentioned location.
