The study included twelve of durum wheat : 1. ACSAD 1367. 2. ACSAD 1393. 3. Douma 51822. 4. ACSAD 1347. 5. Douma 41282. 6. ACSAD 1273, and ACSAD 7. 1305 8. Douma 41063 . 9. Douma 45367. 10. Cham 1. 11- 11. 12. ACSAD 65 and three control ( Cham3, Cham 5 & ACSAD 67). Obtained from the Arab Center for the Studies of Arid Zones and Dry lands (ACSAD) and the General Commission for Scientific Agricultural Research. The experiment carried out in Tel-Hadya station of ICARDA and the second season in a private farm (Al-Moukhtarieh) north of the city of Homs during 2012-2013-2014-2015 years.During 2011-2012 and 2012 to 2013 growing seasons, The effect of water stress which imposed naturally through rain-fed agriculture in the second zone were studied on qualities, productivity and -physiological traits which associated genetically with yield grain, drought tolerance and quality of durum wheat . Also to determine the importance of these traits in improving wheat productivity in conditions to identify superior and use them in half hybridization program to study the special genetic indices.-The randomized complete block design R.C.B.D were used with three replications. Each replication contains six lines with 3 m length, 20 cm between rows. Grain planted at a depth of 3-5 cm and the distance between the plant and the other 5 cm, was excluded four lateral lines and plants terminals of each line of the four internal lines, Fertilizers and agricultural service operations carried out according to the recommendations of the Ministry of Agriculture. The studied characters were: peduncle spike length, number of grains in the main spike, grain weight in the main spike, weight of a thousand grains, water use efficiency, plant growth rate, harvest index, , ratio of wet gluten in grains and the percentage of starch in the grain.Analysis of variance were done using 12 after analyzing the study results were selected superior to most indicators studied a ACSAD 1367, ACSAD 1393, , ACSAD 1347, Douma 41,282, ACSAD 1273, ACSAD 1305 where he introduced in the third season in a complete program to study genetic behavior of some qualities.Third season(2013-2014)1-Selected from the previous two seasons were planted and included in the hybridization in the 20th November 2013 in six lines each father along the line 4 m and minimum separation of 30 cm between the lines, the minimum separation of 100 cm between the father and the other. So that we can carry out the hybridization and in three sowing dates (with interval by week between the deadline and the other) in order to achieve synchronization in the .2-The parents control as they grow, and the formation of each hybrid group has been neutered and vaccinated / 20 / spike from each hybrid group. And make all the crosses at the beginning of the flowering stage (early April 2014) between these models patriarchal way hybridization interactive full. Thus obtained on 42 hybrid group. Fourth Season(2014-2015)1-The parents control were planted with F0 seeds at to obtain F1 generation plants, three replication were used by RCBD. Two rows each replication with 1 m were used by spacing 30cm between rows and 5 cm between plants.2-The models of parental and first-generation plants characterization and then perform interactive analysis to determine the overall estimated impact on the compatibility of the models parental thoughtful, and ability to compatibility groups hybrids produced, and assess the degree of each of the traits and the calculation of genetic variance components effects. Results were analyzed using the computer -the program 12. showed us study the phenomenon of in the debut of the first hybrid desirable moral strength and the moral high with all the traits based on the average of the parents, showing the impact of partial sovereignty and the average father better, showing the impact of high sovereignty.The general combining ability (GCA):The effect of GCA of durum studied and result showed that ACSAD 1393 had high compatibility moral qualities of the number of days to heading and maturity & .ACSAD 1273 GCA for and weight of the flag leaf and spike length, number and weight for grain in the spike, ACSAD 1347, Douma 41282 had high GCA height and the number and weight of grain in the spike. This is a clear indication that these models parental owns the largest number of genes with a cumulative effect and which play an important role in the inheritance of the qualities mentioned earlier. between them (addictive×addictive). This refers to the possession of these genes with a cumulative effect. It is useful to select the follow-up in future generations because it is expected to continue to exceed these hybrids to lower the proportion of genetic segregation. In contrast, many other hybrids showed a compromise, but the genetic interaction where the kind of (addictive× not addictive) and (not addictive× not addictive), this refers to the possession of the largest number of genes that impact the sovereignty and supremacy appear in the inheritance of those hybrids, which means deterioration of the value of the capacity for the continued occurrence of genetic segregation.Variance components:The importance of estimating the refer to the fact that the efficiency of selection of desired trait decrease when this scale decreases, and the results indicated estimate the in durum wheat enjoy the status of space, weight and flag leaf, plant height, length of awn, spike length holder , spike length, number and weight of the grain in the high values. Which shows the importance of the total genetic variation in the inheritance of these traits. degrees of varied from high to low values for other both types. Which is due to the different genetic factors that control these traits to another hybrid depending on the different constituent parents. The spike length high (narrow sense), use of the election as a way the ideal of those qualities.Dominant genes and recessive models between parental unevenly distributed and this gives an opportunity to improve the values of these the future.Graphical analysis:In durum wheat, partial dominant genes controlled with inheritance of number of grains in the spike while the genes of full dominant is responsible for inheritance of weight and flag leaf and spike length holder. as for the rest of the qualities they have dominant superior sovereignty
