Abstract
In the years ahead, wheat, would have more than any
other cereal, on increasingly greater importance as a source
of protein for much of the world’s increasing populations.
Even until now, wheat provides more nourishment for more
people than does any other source. Improvement of wheat would
require increment improvement of its protein content. A protein
fraction could be considered as a primary product of a
structural gene and serves as a marker for that gene. Seed
protein electrophoresis has been widely used to analyse the
genetically conditioned protein fractions in wheat and several
other cereals.
The effect of gamma irradiation on the expression of
genes controlling protein subtractions at the mutant generations
can not be overlooked. Based on the electrophoretic
spectra, selection programs could be executed to screen for
and maintain these mutants that have, a) a voidance of stress
effects through earliness, b) high biological stress resistance,
and c) high potential yield (Kozhemyakin and Ispanov
1984) .
Gamma irradiation doses of 5-15 krad were said to be
suitable for in ducing greater genetic diversity in wheat and
creating mutant forms with positive properties (Khokhlova et
al, 1983; Paladi, 1984; sigida, 198:0; Yanev, 19oO:l; Abd-ElSalam,
1986 and Savov, 1989).
Most places 1n the world are subject to enviromental
stresses (salinity or drought). The Nile Delta is widely
known for its salt- affected soils (Elgabaly et al, 1969
