Ten genotypes of crop peas were obtained from the Organization of ICARDA dry for farming, introduced in reciprocal crosses half were used.

Parents and hybrids were planted using the design of randomized complete sectors (RCBD) with three replicates and recorded data for recipes (duration to flowering 50% and the duration of the seed / day and the number of branches / plant and the proportion of the contract% and plant height / cm and leaf area cm2 / plant chlorophyll / spad length Qurna / cm and efficient winning / g / cm 2).

Analysis of variance showed that the mea squares of the genotypes were siynificant at 1% level of prob .

to all the studied traits .

The dominance genetic variation (H1and H2) was more than from the additive variance (D) for all the studied traits , while when the values of two variance (additive and dominance) were took as a signal to that the genetic dominance variance (H1 and H2) was large in its value from the additive variance for all the studied traits, which can be suggested that the genetic dominance variance was more important in inheritance of all studied traits which gave alabel for using of heterosis in superior hybrids making in this study .

The values of F were pastiviely significant for all the traits unless leaf area cm2 / plant, chlorophyll percentage / spad .

Gene frequency values for dominant alleles to recessive alleles (pq) were less then (o.25) for all the traits , the ratio of number of dominant genes to rescessive (KD/KR) was more than one for all the traits unless leaf cm2/plant ant weight of the seed / gm .

The heritability ratio in narrow sence was low in the traits : The following traits were studied in the two experiments : duration of seed filling / day , proportion of fruting % , plant height / cm .

Where as moderwte in the traits : duration to 50% flowering , number of the branches / plant , leaf area cm2 / plant, chlorophyll percentage / spad, pod length / cm , yield efficiency gm/cm2.

The regression line has been drawn, which gives an idea of the average degree of sovereignty, if gradient X-axis line (vr) arrived under the original point, this indicates the existence of super-sovereign, and if you cut this line axis (wr) Fidel on the existence of partial sovereignty, either when it passed from the point of origin confirms that full sovereignty is control to inherit the trait.

Noting through results table (1), graphs of (1-9) that the regression line cutting axis (vr) down the origin of all the traits points, and this shows that the superior sovereignty is that control its inheritance in all the qualities which reflects the superior sovereignty which are reflected on the hybrid force in most of the traits showed dominant to recessive genes ratio that parents (PO6-OO2FB / FL) and (PO6-OO5FB / FL) and (PO6-OO9FB / FL) and (PO6-O14FB / FL) was one of the most parents and frequent the first part which contains (75-100%) of the dominant gene.
