| Abstract | ||||
| Morphological and technological traits were utilized to identify among canola (Brassica napus, L.) genotypes namely Pactol, Serw 6, Serw 10 and Serw 4. Two field experiments were carried out at the Farm of El-Serw Agricultural Research Station during 2006/2007and 2007/2008 seasons. The results revealed that plants of Line Pactol can be identified by leaf length (blade and petiole), leaf petiole length, plant height (171.1 cm), oil content (44.7%) and branches point (60cm) and its lowest Line in cotyledon length and width, number of siliqua/ plant (286,8) number of seed/ siliqua (22) and seed yield/plant (32.1 g). Plants of Line Serw 6 can be identified with higher number of leaf dentation, plant height (175.9 cm), 1000-seed weight (3.40 g), lowest means in number of leaf lobes (4.5), petiole florescence length (39.9 cm), No. of side branches (6.5) and oil content (40.2%). Plants of Line Serw 10 can be identified with its leaf width (10.1 cm), length of flower petals (1.5 cm), branches point (11.5 cm), lowest means in leaf length, no. of leaf dents (19), length of leaf petiole (7.1 cm) and number of leaves/ plant. Plants of cultivar Serw 4 can be identified by higher number of leaf lobes (5.6), number of leaves (10), petiole florescence length (47.9 cm), number of side branches (13), length of beak (1.2 cm), number of siliqua/ plant (888.1), number of seed/ siliqua (30), seed yield/plant (68.6gm), lowest means in leaf length (21.4 cm), width (7.9 cm), branches point (3.4 cm) and 1000-seed weight (2.77 g). Dice similarity coefficients between genotypes was calculated. Maximum 87% and minimum 62% similarity coefficients were observed between Line Pactol and variety Serw 4, Line Pactol and Line Serw 10, respectively. Base on the cluster analysis, genotypes were grouped into two clusters. Line Serw 10 was in a separate cluster while, Line Pactol, Line Serw 6 and variety Serw 4 were in the second cluster. The results confirmed that some morphological traits and RAPD method could be used for identify among canola genotypes. | ||||
