Abstract
Three field trials were carried out during 2000 and 2001 seasons at three different locations, i.e., Agric. Res. Exp. Stat. of NRC at Kaluobia Governorate and Agric. Res. Stat. of ARC at Giza as well as Ismaillia Governorates. This work aims to evaluate fourteen flax genotypes with regard to straw yield, yield components and technological fiber properties. Estimation of genotypes × environments as well as variance components, heritability and correlation coefficient among straw yield and its components were also reckoned. The results showed that genotypes mean squares values were great enough to reach highly significant levels for all investigated characters. Mean squares of G × Y and G × H × L × Y interactions responded with highly significant and significant for all tested characters except technical stem length, fiber length, fiber percentage and biological yield/plant. High values of heritability (broad sense) were obtained in plant height, technical stem length, fiber length, fiber percentage, fiber fineness and fiber/plant. The results added also that interrelationships between specific economic yield characters and other related characters were reached. However, highly positive significant, positive significant and insignificant negative correlation coefficients were recorded in this work.
