ABSTRACT: To assess the performance and the variability of 49
flax varieties based on agronomic parameters using cluster analysis, a field
experiment was conducted in 2011/2012 and 2012/2013 winter seasons at the farm
of the National Research Center at Nubria district, Albehira Governorate,
Egypt. The results revealed high significant difference among all flax
varieties in all the studied characters. Letwania-9 and Evelen cultivars
surpassed all other varieties in seed and oil yields/fed. On the other hand,
D variety gave the lowest value of seed yield/fed and F variety gave the lowest
values of oil% and oil yield/fed. While, G Variety surpassed all other
varieties in straw yield/fed. Blanka variety recorded the lowest values of
straw yield/fed and biological yield/fed, while, Posna variety gave the lowest
values of technical stem length (cm). In cluster analysis, all the studied
characters were used to construct a distance matrix using the Euclidian
coefficient, and generate dendrogram showing dissimilarity among all the
varieties. Distance coefficient was ranged from 1.2 between Piltstar and
Litwania-1 varieties and 10.8 between Posna and G varieties, which reveal the
genetic diversity among varieties. The varieties can be divided into 4 groups
based on cluster analysis.
