Abstract
The research was carried out at the Center for Agricultural Scientific Research in Latakia during the 2016 and 2017 seasons; the plant material included 23 genotypes of sesame in the fourth generation. in order to study the differen characteristics of the studied genotypest to elect the best and adopt them later as new varieties select or to introduce them into breeding programs. The results of the research showed that there were significant differences between the sesame genotypes, the genotypes (17) significant superior to the average height of the plant (172.5 cm) over the rest of the genotypes, as well as the number of branches/plant (4.22 branches/plant), as well as the genotypes 17 recorded highest value for the number of capsules (163.6 capsules) and capsule length (4.33 cm) and capsule yields (8843 kg/h). the genotypes 2 recorded the highest weight (4.99 g), while the 19th genotypes was characterized by the highest seed yield (2791.58 kg/h), followed by genotypes 17 (2663.16 kg/h (20-6-15-12-7-13) also excelled. The net yield ratio was (70.8%) for the genotypes (14) whichsigfnificantly outperformed the rest of the genotypes. The genotype (16) also recorded the highest protein percentage (30.08%), and the two genotypes 9 and 6 outperformed in oil percentages (55.75, 55.22%).compared to the rest of the genotypes. A positive significant correlation has bee found between seed yields, plant height, number of branches per plant, number of capsules, capsule length, capsule yield, and net yield ratio, so it can be done yield selection through its aforementioned components. A positive significant correlation was also observed between oil percentage, and protein the number of branches, yield of capsules, length of capsule, and number of capsules, while a negative correlation was found between oil percentage and net yield ratio. The selection for number of capsules increases seed yields so it is considered the best way to increase oil percentage.
