الملخص الإنجليزي

The comparative study was conducted among twelve (Brassica napus L.

) genotypes at Grdarash field, College of Agriculture, Salahaddin University-Erbil during the growing season of 2014-2015.

The randomized complete block design with three replicates was used.

The results of statistical analysis indicated to record the highest value of protein for the seeds and cake (27.75 and 28.74 % ) from Rendy genotype respectively.

The highest values (60.19 and 20.93 % ) of oleic and linoleic acid was recorded from Bacara genotype, while the highest value (5.835) of Linolenic obtained from Pactol genotype.

The significant correlation coefficient was obtained between seed yield secondary branches, number of siliques, seed index, biological yield and harvest index with r= 0.79**, 0.66*, 075 **, 0.86** and 0.74** respectively.

The path coefficient analysis confirming direct and indirect effects seed yield, the maximum positive direct effect on seed yield was obtained by the traits biological yield (0.832) confirm the positive contribution of this traits on seed yield followed by harvest index (0.324) and days of elongation (0.263) while days of flowering, days of physiological maturity, number of secondary branches and number of silique per plant recorded negative direct effect on seed yield with (-0.142, -0.126, -0.022 and -0.078) respectively.

Cluster analysis or dendrogram classified the genotypes into three main clusters depending on growth stage, Agronomic characteristics and quality of them.
