| Abstract | ||
| The study was carried out using 11 introduction genotypes of the durum wheat ( DW36 ، DW30 ، DW7 ، DW17 ، DW45 DW38 ، DW26 ، DW10 ، DW15 ، DW47 ، 22)in addition to registered and certified in Iraq (Baghdad) and the crosses them were made according to the partial diallel cross system to study GCA effects and type of gene>action that controlled number of days to 50% flowering، plant height، leaf eara، number of spike ، number of>grain per spike ، 1000 grain weight and grain yield per plant.The results showed that mean square of genotypes , gca and sca was highly significant for all traits except number of spike.The ratio of σgca/σsca components was grater than unity for days to 50% flowering، number of spike، number of grain per spike suggesting that additive component was importane to control these traits and the selection>in early>generation may be>fruitful for>more>traits. while the other traits were controled by non-additive gene effects and over dominance>gene>action. Parents 1, 4, and 11 were Distinguished as a desired effects of the most of traits and it was possible to use their breeding value in hybridization programs to improve their traits | ||
