Abstract
Two field experiments were conducted at Giza Agric. Res. Stat. During 1994/95 and 1995/96 seasons to evaluate fourteen flax geno‌types in relation to yield, yield components and technological characters in addition to some genetic parameters. The results obtained can be summarized as follows: 1.Either straw or seed yield and their respective components showed highly significant differences in each character among the fourteen flax genotypes, where S.420/140 recorded maximum estimates for total plant height, technical length, straw yield/plant as well as per faddan, long fiber yield, fiber length and long straw yield/plant as well as per faddan, long fiber yield, fiber length and long fiber percentage. Meanwhile, Giza 8 cv. ranked first and surpassed the other flax geno‌types in seed yield and its related traits. Moreover, S. 2465/1 reached high magnitude regarding oil percentage. On the other hand, Gawhar cv. was the lowest in all both yield and yield components. 2.Phenotypic and genotypic variance reached highest estimates con‌cerning fiber fineness, number of seed/plant, total plant height, fiber length and technical length. 3.Estimates of genetic coefficient of variation (G.C.V.) as well as pheno‌typic coefficient of variation (P.C.V.) and genetic advance expected from selection as a percentage of general mean, revealed high values in fiber fineness, straw yield/plant, main stem diameter, fiber length and seed yield/plant. 4.Heritability ratios were higher in all fourteen flax characters except characters number of seed/ plant and number of seed/capsule which recorded lowest heritability ratios.
