الملخص الإنجليزي

The study was performed in AL- Hamra region.

The distance was (15) KM from Salahddin govenorate Center / Tikrit according of factorial mating design wheat (Triticum aestivum L.) .

factorial mating design was conducted of wheat crop for winter sowing season (2016-2017) to abtain (24) single crosses depend of varieties (AL noor, AL Hashma , AL- Barka , AL Rasheed , AL Adanina and Tamoz 2) as Male parents and( Abo Graib3 , Sham6 , IPA 95 , IPA99) as Female parents.

The seed was obtain from improvement seed center in salahddin govenorate / Tikrit to estimate some genotypes parameters of wheat .

the genotypes parents Ten varitieses and twenty four Single Factorial crosses sown in field crops station department _ college of Agriculture _ university of Tikrit.

In winter sowing season (2017_2018).

the experiment was conducted of Randamized compelete Block Design ( R.

C.

B.

D) with three replicates.

The studied traits was included number of day until (50%) flowering , height plant , spike length , leaf area , number of grains / spike , 1000 grain weight , yield seed / plant, biological yield and harvest index.

The results show are of variances of parents for all triatis the hybrides showed high significant difference at (1%) for all studied same parent show general combining ability.

The parent (al rasheed) showed significant of general combining ability for six traits and female parent (Sham6) and (IPA95) ware gave positive general combining ability for five traits.

The factorial crosses (Al hashma x Sham6) and (Al rasheed x IPA99) showed positive significant of specific combining ability for four traits .Narrow sense heritability was high for traits number of day until (50%) flowering, spike length, single plant yield and biological yield a was low for leaf area traits.

The while the values expected genetic as percentage were moderate for traits.

Number of day until (50%) flowering, 1000 grain weight, single plant yield and harvesting ting index.
