| Abstract | ||
| The study was performed during the 2014 – 2015 season at Abu Gharib experiment station which belong to the Agriculture researches office Using seven bread wheat varieties (Ebaa 99, AL Fateh , Bhooth22 , Bhooth10 , AL Rasheed , AL Barakah and Orok)to find the response of these varieties to four planting dates (15Nov.,1Des.,15Des.and 1st.Jan)Split plot desing in RCBD with three replications, main plots were assigned to planting dates, while sub-plots were for wheat varieties. Planting date at 15 november gave higher grain (5448) KG.h-1 that’s a result of supervised in no. spikes. m-2 (336), no. grains.spikes-1 (69) and 1000 grain weight (37.02) gm, Than the rest planting dates, white 1 jun. gave low grain yiled (1501)kg.h-1 . Significamthy differences appeared among cultivars in studied traits especially Ipaa99 cultivar which gave highest range of plant hight (91.85 cm) , flag leaf area(31.88 cm2) ,1000 grain weight (32.92), grain yield (3726 kg.he-1) and harvest index(32.91%),,days to 50% anthesis (124.25day),days to full maturity (150.17day) and biological yield(11735day) There was significant interaction between planting dates and cultivars in all traits studied. Buhooth22 and Al-Baraka that planted at 15Nov. gave highest means in number of spike per m2 , number of grain per spike, grain yield and harvest index. (380,359), (73,76), (6100,6100) and(48.7,49.8)% respective | ||
