Abstract:
Field experiment was carried out in three locations, (Agricultural Research Centers in Homs, Hama, and Al-Ghab), Syria, during tow growing seasons (2019/2020 and 2020/2021), in order to study the performance of six monogerm sugar beet varieties (Vico, Dita, Semper, SR305, Osma and Rosella) under three locations for yield and yield components along with technological traits. The experiment was laid out according to a randomized complete block design with three replicates at each location. The results of statistical analysis showed significant differences (P≤0.05) among all studied treatments and interactions among them for all investigated traits. The highest value of total soluble solids (TSS) percentage was attained by variety SR305 at Hama location in second season (23.50%). Meantime, Osma and Semper varieties achieved the highest value of sucrose percentage under Hama location conditions in second season (18.70, 18.30%) respectively. For purity percentage the highest value of purity percentage was produced by growing Semper variety at Hama location in second season (93.06%). Regarding root yield and extractable sugar yield the highest value of these traits was given by Semper variety at Homs location in second season (156.12, 23.97 ton/ ha) respectively. The obtained results also showed that growing seasons had a significant effect on all studied traits except for sucrose percentage, where second season surpassed the first one in purity percentage, root yield and extractable sugar yield recording (84.39 %, 106.32 and 15.43 ton/ ha) respectively. With respect to locations, Hama location recorded the highest value of root yield and extractable sugar yield (118.26, 16.92 ton/ ha) respectively compared to Homs and Al-Ghab locations, while no significant differences were found among locations with regard to quality traits. Also results indicated that varieties significantly differed in the studied traits except for TSS (%). Variety Semper performed best in relation to all studied traits and in all locations.
