The research aims to compare the performance of genotypes (Syria and Jordan) of durum wheat under rainfed conditions in the regions of stability first (Plant Research Centre) and second (Glenn) by examining the influence of factors Sowing date, seeding rates and location. They considered the 8 patterns of durum wheat from Syria (Sham 3, always 1, 1229 and always ACSAD 41 008) and Jordan (Hourani, 27, ACSAD 65, P-8 strain promising Umm Qais).

The experiment was planted on 20/11/2008 for a first date, Pima County was second date 14/12/2008, and the third time was in 8/1/2009 in both locations. The research also involved the For three seed rates (15,20,25 kg / sq.m) for each appointment.

The results showed no significant difference between the dates first, second and third time on the supremacy of the status of plant height as the average length 79.53, 79.36 and 73.12 respectively.

As for the number Actaouat noted that there is no significant difference between the first and second dates, and between the second and third hand, where the values of the average number of Actaouat 4.22, 3.84 and 3.67, respectively.

It was also noted the lack of significant difference between the dates I, II and III supremacy on the date of the status of 100 grain weight and mean values were 53.94, 52.64 and 44.66 GMT

With respect to grain productivity The impact of agriculture, where later than the first date, followed by thesecond appointment Vaii by far the great moral values, where the grain productivity 2509.2221 and 1883 kg/ha,respectively,

Keywords: location, date, density, varieties, wheat and tough.

هدف البحث إلى مقارنة أداء أنماط وراثية (سورية وأردنية ) من القمح القاسي تحت ظروف الزراعة البعلية في منطقتي الاستقرار الأولى (مركز بحوث ازرع) والثانية (جلين) وذلك بدراسة تأثیر عوامل موعد الزراعة، معدلات البذار والموقع. كما تم دراسة 8 أنماط من القمح القاسي من سوريا (شام 3، دوما 1، أكساد 1229 ودوما 41008) ومن الأردن (حوراني 27، أكساد65، ف8 سلالة واعدة وأم قيس). كما تم زراعة التجربة بتاريخ 2008/ 11 /20 للموعد الأول، بینما کان الموعد الثاني 2008/ 12 / 14 ، أما الموعد الثالث فكان في 2009/ 1 / 8 في كلا الموقعين. كما شمل البحث على ثلات معدلات بذار ( 15, 20 ,25 كغ/ دونم) لكل موعد.
