Abstract

Experiments were carried out at Qarahta Research Station and Hama Research Center during the growing seasons 2016 and 2017. Four varieties were studied and three sowing dates, in order to identify the optimal planting date (1^st February, 15^th February and 15^th March) and the best variety (NSL-106398, AMS-13923, AMS-13761 and Zeer) in terms of yield. The Results of compound analysis of flowering days showed significant differences (P≤0.05) between locations, planting dates and varieties. The earliest was Qarahta location, third sowing date and Zeer variety (75, 59, 72 days) respectively, the same differences obtained for physiological maturity on third sowing date (114 days) and Zeer variety (120 days). The plant height had significant differences between locations and varieties where the highest values were for Hama location (157 cm), second sowing date (149 cm) and AMS-137161variety (168 cm). The heads number per plant showed significant differences for location, sowing dates and varieties and the highest values were for Qarahta location, first sowing date and AMS-13923 variety (8, 9, 9 heads) respectively. The grain yield showed significant differences, the highest grain yield was in Hama (3.510 t/ha), first sowing date (2.980 t/ha) and Zeer variety (3.620 t/ha). Zeer and NSL-106398 varieties and early sowing dates from 1^st to15^th February are recommended to plant in Syria.
