Studies on some double purpose flax (linum usitatissimrm l.) genotypes grown under the Egyptian delta conditions [electronic resource].

Includes reference.

Two field trials were conducted at Sakha Agric. Research Station during the two successive seasons 200412005 and 2005/2006. These investigations included four double purpose genotypes of flax i. e., Sakhal, Strain 22, Sakha 2 and Giza 6, which were studied the botanical characters and evaluated in relation to straw, seed yield and their component. The results obtained could be summarized as follows:- . 1- Flax genotypes showed significant differences in all characters, viz., technical stem length, upper branching zone length, main stem diameter, straw yield per plant, number of capsules per plant, number of seeds per plant, seed yield per plant, straw yield per feddan, seed yield per feddan, oil seed percentage, oil yield per feddan and iodine number. 2- The promising strains 22 surpassed the other flax genotypes in all seed and technological characters and followed by Sakha 2, Sakhal and Giza 6, respectively. 3- Sakha 2 sutpassed the other genotypes in most anatomical parameters. It produced the highest values of fiber layer thickness, diameter of fiber and root, all leaf parameters and cotyledon thickness.
