| Abstract | ||||
| Two field experiments were carried out at Ismailia Agric. Res. station Agric. Res. Center, Egypt, during the two seasons of 2000/2001 and 2001/2002 to study response of yield, yield components and fiber properties of seven flax genotypes to N levels in newly reclaimed soil. A spit plot design with four replications was used with varieties (Sakha 1, Sakha 2, S.329/2118n, S.40213/5/10. S.402121/20/3, Ariane and S.288/37/14/8) as main plots, whereas nitrogen levels (50,65 and 80 kglfad) as sub plots in both seasons. The results obtained could be summarized as follows: 1- Flax strain (40213/5110) gave the highest plant height, technical length. Sakha 1 variety gave the highest straw yield per plant and per faddan while Sakha 2 variety gave the highest number of capsules/plant, seed yieldlplant seed index, oil percentage and oil yield per faddan. On the other hand, Ariane ranked the first for fiber yield/faddan, fiber percentage and fiber fineness. However, it gave the lowest seed index, oil percentage and oil yield per fad dan:"" 2-The highest straw yieldlfad was obtained by applying 80 kg Nlfad to sakha1 in addition, the highest seed yield per faddan oil yieldlfad was obtained by applying 80 kg Nlfad to Sakha 2, while the highest fiber yieldl faddan was obtained from 80 kg Nlfaddan with Ariane. The highest value of fiber fineness resealed from 50 kg Nlfaddan with Ariane. 3- Straw yield 1 plant was significantly and positively correlated with each of seed yield /plant and oil percentage. Also, a significant positive correlation between seed yield Iplant with number of capsules/plant, 1000-seed weight and oil percentage was recorded. These results indicated that maximization of could be achiveded by selection for these traits: (number of capsuleslplant and seed index). Conceming fiber length data showed significant positlve correlation with technical length. Seed index showed positive correlation with oil percentage. On the other hand, fiber fineness was Significantly and negatively correlated with each of oil percentage and straw yield Iplant. | ||||
