Two field trials were conducted at Sakha Agric. Res. Station Farm. during the two succH-tqivc seasons of 200312004 and 200412005. This investigation included two flax gent-twee (Sakha 1 and Escalina) as affected by sowing density (1500. 1300. 2100 am! 9.400 seeds/m2) and some retting methods (still water; water changed every 48 hours and streaming water). The treatments were arranged in cv. split—split design with four replications. The results obtained could be summarized as follows: 1. The differences between cultivars were highly significant in, fineness. strength, fiber yield pe: fee and total fiber percentage. 2. Escalina cultivar was superior in these above characters compared with Sakha 1. whereas Sal 3' :1 1 was superior in fiber length than Escalina. 3. Increasing st wing density from 1500 upto 2400 seedsim2 increased fiber yield and Its quality. 4. The highest vaiues of fiber fineness and fiber strength. fiber yield per fed and fiber percentage were obtained by retting in streaming water. 5. Still water gave the lowest value in fiber fineness and fiber strength. 6. Effect of all interactions between cultivars. sowing density and retting methods were highly significant on all technological characters and fiber yieldffed.
