| Abstract |
Two filed experiments were carried out at Zarzoora Exper. Stat., Beheira Governorate, during1999/2000 and 2000/2001 seasons to investigate the effect of genotypes and harvesting dates on yield, fiber quality and seed chemical composition of flax. Data indicated that the new strain402/1 produced the maximum values of total plant height, number of seeds/ capsule, seed index, straw yield per plant as well as per fed and seed yield/ plant as well as per fed . The imported variety Vaiking recorded the highest mean values for the technical stem length, fiber length, fiber percentage, fiber fineness and fiber yield/plant as well as/ fed., while it recorded lower mean values of straw and seed yield. The highest crude fat% in flax seeds(41.53%) was obtained by the new strain 366/2/1/2. Data also illustrated that the highest mean value for straw yield per plant or per fed and the best flax quality resulted from plants which were harvested at the medium date; while plants harvested at the late date produced the highest mean values for seed yields. SDS-PAGE revealed different changes in electrophoretic patterns of water soluble protein fractions which could be taken as a good tool to distinguish between the six flax seed genotypes. On the other hand, the similarity levels (SLs) generated from cluster analysis of protein patterns revealed that we canno,t use the protein patterns as a biochemical marker since no changes were noticed in protein pattern of flax seeds through the different times of harvesting . Also the GC analysis of fatty acid composition revealed that linolenic acid was the predominant unsaturated fatty acid while, stearic and arachidic acids were the main saturated fatty acids present. It could be noticed that S.366/2/1/2 genotype has higher oleic and linoleic acid content but less lenolenic acid content when its plants were harvested after 165 days (the late date) compared with other genotypes. By the same taken, S.402/1 genotype has higher oleic acid content (6.20%), higher linoleic acid content (16.50%) and less lenolenic acid content (34.60%) when its plants were harvested after 145 days (the early date). So, it is worth to mention that, the oil of these two genotypes could be used in nutritional purpose and the other genotypes with higher content of lenolenic acid could be used in industrial purposes, when their plants are harvested at early date.
