Abstract
The study was conducted at Al-Ghab Research Centre, General Commission for Scientific Agricultural Research (GCSAR), Hama, Syria, during two growing seasons 2012/2013 and 2013/2014. Eight primitive wheat genotypes; C49, C57,and C64 belongs to Ttiticum carthlicum; P149,and P193 belongs to Ttiticum polonicum; D94, D124, and D67 belongs to Ttiticum dicoccom, and two local cultivated varieties sham3, and sham5 (as control) were planted in randomized complete block design in three replications. Yield components (number of fertile tillers, number and weight of grains per spike and weight of thousand grain) were studied and compared to the control and also the correlation coefficient between the studied traits was determined. Results showed that the genotype D94 was significantly superior in number of fertile tillers comparing to both controls, and the genotype P194 was significantly superior in weight of grains per spike with an increase rate (76.65, 97.99)% as compared with both controls, sham3, and sham5, respectively, and also was significantly superior in weight of thousand grain with an increase rate (72.73, 107.28)% as compared with both controls; sham3, and sham5 respectively. The results also showed a positive correlation between number of grains per spike and with each of weight of grains per spike and weight of thousand grain.
Key Words: Genotypes, Primitive wheat, Yield components, Correlation coefficient.
