This investigation was conducted at Gemmiza Agric. Res. Station during the two successive winter seasons of 2014/2015 and 2015/2016 to study the differences among nine flax genotypes namelyline 541/D/10, Sakha 2, line 402/11/6, Sakha 3, Giza 9, Ilona, line 22, line 2467/3 and line 435/11.The experiments trails were carried out in Randomized Complete Block Design (RCBD) with four replications. Results revealed that the flax line 541/D/10 ranked the first and surpass the remain flax genotypes in biological yield/fad., straw yield/fad., fiber yield/fad., fiber %, fiber length, seed yield/fad., seed index, oil %, oil yield/fad., Iodine value, crude protein %, in seeds and total carbohydrates % in seeds. But this line occupied the fourth position concerning fiber fineness trait. The flax variety Giza 9 ranked second in all fiber characters, while line 2467/3 was the fewest in biological yield/fad., straw yield/fad., fiber yield/fad. and fiber percentage. The line 22 ranked second regarding seed yield/fad., oil % and oil yield/fad. The flax variety Ilona achieved highest estimates for cellulose %, moisture % in seeds and crude fiber % in seeds. On the other hand, Ilona gave the lowest estimates in seed yield characters. Correlation coefficient(r) values were highly significant and positive between fiber yield/fad. and each of biological yield/fad., straw yield/fad., fiber %, fiber length, fiber fineness, lignin % and waxes %. While it was significant and positive with each of cellulose %, and pectin %. The( r ) values recorded highly significant and positive between seed yield/fad. and each of oil yield/fad., seed index, oil %, total crude protein % (in seeds) and total carbohydrates % (in seeds). While correlation coefficient(r) values were significant and positive with either Iodine value and crude protein% in seeds.
