Abstract: 

These Experiments had been done in The Agricultural Scientific research Centre in Lattakia, where 24 Types of red and green Okra were Collected from different altitudes (25 – 650) meters. This work Continued for 10 years (2006-2016). These types were planted within an experimental pieces of 11.2 m² square, and the distance between each piece and another is 50 meters in order to reduce the Cross-pollination. Both of the general and the special Criterions had been considered during the individual plant Selection. During the first and the second years of the Selection, the bad and strange plants had been removed, 12 types out of 24 were selected. Then, in the next two years, individual plant selection had been lasted after covering the selected plants of every type with mosquito net in order to reduce the Cross-Pollination among the types. In the third and fourth years of the Selection, only two types out of twelve were selected; one of them had green pods and the other had red pods. Individual plant selection had  been lasted more over 4 consecutive years until plants had become  identical, with wanted qualities, and high productivity. The two selected types were compared with 3 okra varieties (OK 100, suzie F1 and lady finger). The yield of the two selected local types (421.7 and 415 g/plant) were better than suzie F1 and Lady finger (191.6 and 262.8 g/plant), whereas no significant differences were observed between the local types yield and  OK 100 yield (336.5 g/plant). 

key words:  Types, Individual plant Selection, Okra (Abelmoschus esculentus L.).
