The present study deal with the identification of some cultivars of Pyrus communis L. mainly ( Karmen , Konphrs , Zafrane and Willyam ) planted in different places of Mosul city . The morphological characters involved ( Bud , stems . leaves , flowers , fruits seeds , and indumentnms ) .
The results indicates that the leaves and fruits have a good value to separates and identified .
The cultivars palynological study showed that pollen grains differ for shape and dimension in polar and equatorial view and were found to be tricolporate .
The results of chemical study showed that (8) phenolic compound were identifiel in all conolic exraction of leaves , They were ( Querecetin , Querectin-7- glucoside , Myrcitine , Rutin , Luteoline-7- glucoside , Luteoline , Kampforal and Apigenine ) .
This result showed a good value to identification the cultivars .

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.

A field experiment was conducted for two consecutive seasons 2008-2009, 2009-2010 at AL-Quba location in the west north region of Mosul city at Nineveh region to study the effect of planting density on the performance of two sunflower cultivars; namely, Mehran and Sunbred. The plants were sown at four planting densities: 41666, 47619, 55555 and 66666 plants.ha-1, respectively. The data were statistic analyzed by using factorial experiments in randomized complete block design with three replications. The results indicated that the stem diameter, leaf area, head diameter, number of seeds per head, weight of thousand seed, hulls, fertility percent, harvest index and seed yield per plant, oil and protein content of the seeds decreased with increasing plant density. Increasing plant density cases significantly increase in seed yield per unit area and oil, protein yield. The differences between the two cultivars cultivation were significant in all the studied characters, except protein yield in 2008-2009 season, protein content of the seeds in 2009-2010 season. The higher seed yield of Mehran cultivar was associated with higher flower disc diameter and greater number of seeds per flower disc. Based on what has been presented in this study, could be concluded that the plant density of approximately 66666 plants.ha-1 is the optimum for sunflower crop cultivation, and Mehran cultivar proved be more promising than Sunbred cultivar.
