ABSTRACT. The present study aimed to estimate the type of gene action
of the different flax traits including technical plant length, number of
capsules/plant, seed yield/plant besides oil content and fatty acid composition
of the oil from genetic study of six populations, i.e., P1, P2,
F1, BC1, BC2 and F2 of the cross between Egyptian cultivar, Giza-8
and the Netherlandish cultivar, Viking through 1998/1999 to 2002/
2003 seasons at Alexandria, Egypt. Significant genetic variance were
showed for the studied traits. Additive genetic variance contained the
major component in the inheritance of seed yield and number of capsules/
plant while both additive and dominance variance were significantly
equal in technical plant length inheritance. Oil content and
linolenic fatty acid were genetically controlled by additive gene effect
while palmitic, stearic, oleic and linoleic acids are genetically controlled
by dominance gene effect. Heritability estimates (broad-sense)
were 91.72, 76.75, 71.33 and 87.97% for seed yield/plant, number of
capsules/plant, technical plant length and oil content, respectively. For
fatty acids, heritability estimates (broad-sense) were 69.40, 83.09,
92.80, 85.38 and 89.60%, respectively. In narrow-sense, heritability
estimates were 83.65, 57.79, 37.28 and 75.00% for seed yield/plant,
number of capsules/plant, technical plant length, and oil content, respectively,
while for fatty acids composition were 22.70, 26.67, 32.04,
32.28 and 56.36% for palmitic, stearic, linoleic and linolenic acids respectively.
As, for the predicted gain from selection, the values were
93.05, 35.95, 10.90, 10.32, 7.72, 90.01, 13.48, 11.04 and 25.52% for
seed yield/plant number of capsules/plant, technical plant length, oil
content, and fatty acids, i.e., palmitic, stearic, oleic, linoleic and linolenic,
respectively. |
