Abstract: 

Almond is economically one of the important fruit crops especially nut fruits in Syria according to the fact that the wild genetic resources still exist along the Syrian forests, mountains, and hills. The study was conducted on the agricultural research center of Homs; Syria aimed to study self-incompatibility for some introduced Italian varieties of Almond. (Prunus amygdalus L.) Results revealed an existence of complete self-sterile varieties such as Feragnes and Don carlo, and varieties varied according to the results of free fertilization in fruit setting rates; for example Touno and Genco varieties had the highest fruit setting rates (32.9585% and 32.0996% respectively). However,Filippocco and Supernova varieties recorded the lowest fruit setting rates (11.7742% and 11.8184% respectively). Genco, Tuono,Doncarlo, Feragnes, Filippocco and Pepparudda varieties varied according to pollen viability between 88.6300% for Genco and 70.7100% for Pepparudda but in the other hand the variety Supernova pollen viability was the lowest by 60.4263%. Genco occupied the highest rank in pollen germination rate by 76.0763% butFilippocco had the lowest pollen germination rate by 60.4263; in parallel ofthat,Genco had the highest fertility index while the lowest was for Filippocco.
