Field experiments were conducted during 2001/2002 and 2002/2003
seasons in seven locations representing flax growing regions in Egypt, namely Sakha
in Kafr EI-Sheikh Governorate, EI-Gemmeza in EI-Gharbia Governrote, Kafr EI-Dowar
in EI-Behaira, Shirbeen in EI-Dakahlia Governorate; Kafr Saad in Damietta
Governorate, Diyarb-Nigm in EI-Sharkia Governorate and Shebeen EI-Kanater in EI-
Kalubia Governorate. Two flax genotypes (Sakha 1 and Belinka) were evaluated in
these location with regard to straw and seed yield and yield components as well as
some technological characters. The combined analysis of variance for the seven locations and two seasons         was done. Results could be summarized as follows:                                   . The cultivar Sakha 1 significantly exceeded the cultivar Belinka in fruiting zone length,
straw yield per plant and per feddan, number of capsules per plant, number of seeds
per plant, seed yield per plant and per feddan, oil percentage and oil yield per feddan.
The inverse was true in technical stem length, fiber yield per feddan, fiber length, total
fiber percentage, fiber fineness and iodine value. EI-Dakhlia location was superior the other six locations in technical stem
length, fruiting zone length, straw yield per fed., number of capsules per plant,
number of seeds per plant, seed yield per plant and seed yield per feddan, fiber yield
per feddan, fiber length, total fiber percentage, oil percentage and oil yield per
feddan. The highest fiber fineness and iodine value. were obtained in Kafr EI-Sheikh. Significant increases were recorded in the second season for: technical stem length,
fruiting zone length, straw yield per plant and per feddan, number of capsules,
number of seeds per plant, seed yield per plant and per fed., fiber yield per plant, and
oil yield per fed. But the highest iodine value was recorded in the first season. Season had no significant effect on fiber yield per feddan, fiber length, total
fiber percentage, fiber fineness and oil percentage. Interaction between genotypes and location and between genotypes and seasons
significantly affected on most studied characters. The highest straw, seed and oil yields per feddan were produced by Sakha 1 grown in
EI-Dakhlia, whereas the fiber yield per feddan was produced by Belinka grown in EI-
Dakahlia. The present results show clearly that EI-Dakahlia location is superior to
other locations in producing high yields of seed and fiber.
