Two field experiments were carried out at Ismailia Agric. Res. Station, Ismailia Govemorate, during 2002/2003 and 2003/2004 seasons to investigate the influence of some flax genotypes and pulling date on flax yield, yield components and fiber quality. The obtained data recorded that the promising strain 2465/1/3 (which released by fiber crops Res. Section in Giza Agric. Res. Station), surpassed the local cultivar Sakha 1. and the other investigated strains, in all flax yield and its fiber quality traits, this result, may be due to that 2465/1/3 strain has high adaptation in the newly reclaimed sandy soil, but Sakha 1 Cv. has poor adaptation in the same region. Data illustrated that medium pulling date (150 days after sowing), significantly gave the highest mean values of all tested parameters for flax yield and its quality.
