| The study includes grown of (5) uniblnds : A 20 Prls/Pews/3/TJB368.251/BUC//CUPE B 41 ACSAD529/Ducula C 60 ACSAD875/5/CS/E.Gig/CS/3/3*PVOS/4/K134(60)/VEES D 53 ACSAD875//URES*2/PRLS E 7 ACSAD875/3/TJB368251/BUC/CUPE and (5) Biblendes in portens of mixing a ratio (1:1) Each pure lines was used twice in the Biblends , and (5) Tetrablends of Biblends were alse implemented provided that each twice only in each Tetrablends and portions of mixing a ratio (1:1) for each Biblends in coded in Tetrablends under two sowing rate (160 - 240)kg/ha . The experiment was concducted during the winter season (2011- 2012) in two locations . The first was in Al-Hawija region south west of Kirkuk . The second in the fields of Agriculture College – University of Tikrit . The uniblnds and Biblends and Tetrablends by using Grouped Balanced Block in split – plot design with three replications . The following characters : (flag leaf area (cm2) , plant height (cm) , grain yield kg.ha-1, biological yield kg.ha-1 , harvesting index(%) and Efficiency yield . The results of the study can be summarized as follows : sowing rate affected significantly of the studied thats and the high rate sowing exceled plant height ) 106.8 , 98.8 ( cm , grain yield (5406.6 , 4966.8) kg/ha , biological yield (16832.0 ,16980.6) kg/ha, harvesting index (35.32 , 33.08)% and Efficiency yield (0.172 , 0.150) in the two of Al-Hawija and Tikrit locations respectively while The sowing rate excel in flag leaf area (24.3 , 21.3) cm2 in the two locations of Al-Hawija and Tikrit respectively . The groups show significant differences in the trailstraits studied , Tetrablend were superiors in plant height )102.4 , 95.5 ( cm and efficiency yield )0.169 و 0.149) and grain yield (5404.4) kg/ha in the locations of Al-Hawija and Tikrit respectively , and the biological yield (16576.0) kg/ha and harvesting index (32.10)% in the location of Tikrit . whereas The group uniblnds exceled in flag leaf area (24 , 21.2) cm2 in the two locations of the study . The uniblnds significant differences in most of the characters studied and the line (B) in the property of plant height )104.5 , 100.1( cm grain yield (5542.9 , 5153.4) kg/ha , biological yield (117221.7 , 17085.3) kg/ha , harvesting index (38.52 , 35.82)% and efficiency yield (0.172 , 0.142) in the both locations and line (C) in flag leaf area (24.6) cm2 in the location of Al-Hawija , and line (D) in flag leaf area (22.5)cm2 in the location Tikrit . Biblends gave significant differences in most of the properties studied . The blend (A B) excelled in plant height )110.1 , 99.9( cm in the both locations . The blend (A B) excelled in efficiency yield (0.179) , and blend (B C) excelled in grain yield (5312.3) kg/ha and blend (C D) in flag leaf area (24.7) cm2 in the Al-Hawija location , and blend (A B) in grain yield (5616.8) kg/ha harvesting index (35.96)%, biological yield (16927.3) kg/ha , efficiency yield (0.152) and blend (D E) flag leaf area (21.9) cm2 excelled in Tikrit location. The Tetrablend showed significant differences in most of the properties studied and the blend (D E + A E) excelled in flag leaf area (24.1 , 21.1) cm2 in the both locations and the blend (B C + C D) in plant height )106.6( cm and harvesting index (43.00)% and blend (C D + D E) in and grain yield (5678.3) kg/ha and the blend (A B + A E) biological yield (17784.9) kg/ha efficiency yield (0.182) in the Al-Hawija location . the blend (B C + C D) excelled in plant height )99.9( cm biological yield (17460.4) kg/ha and the blend (A B + A E) in harvesting index (35.46)% and Efficiency yield (0.157) in the location Tikrit . | ||
