Abstract
The study included two field experiments for rapeseed crop (Brassica napus L.) conducted during two winter successive seasons 2008-2009, 2009-2010 at AL-Rashidia location which is far about (22 km) west north Mosul city. Each experiment was conducted according to factorial experiment in randomized completely block design with three replications. Its included three plant population (55555, 83333 and 166666 plants. hectar-1) with three cultivars of rapeseed crop (Kara, Rafal and Bristol). The results could be summarized as: The plant population of 55555 plants. hectar-1 gave the highest mean for characters stem diameter, number of primary branches, number of silique /plant, leaf area, number of seed per silique, weight of thousand seed, and oil, protein percentage in 2008-2009, 2009-2010 seasons, While the plant population of 166666 plants. hectar-1 gave a high mean for plant height in both growing seasons. The cultivars differed significantly in all the related characteristics, the Rafal cultivar come over the other cultivars in plant height, stem diameter, number of branches/plant, leaf area, number of silique /plant, number of seed/ silique, 1000 seeds weight (g.) seed yield (ton.ha-1), oil, protein percentage of seeds and oil, protein yield (ton.ha-1)in both growing seasons. The interaction between plant population and cultivars was significant in plant height in 2008-2009 season only, the Rafal cultivar with plant population at 166666 plants.hectar-1 gave highest plant height.
