However, there was no within variety diversity
observed as a result inter- variety genetic diversity
yielding a value of 0.3663. The G
ST
parameter
(relative magnitude of differentia-tion among varieties)
was reasonable 1.000, explaining the low value of
estimate of gene flow (N
m
) which was 0.000.
3 Conclusion
Protein profiling of selected genotypes have been
found effective to differentiate the selected genotypes
of wheat. We had identified certain protein bands of
17 kd (10%) and 66 kd (15%) exclusively in salt
tolerant genotypes. However protein profiling was not
as effective as molecular marker but it can be very
useful for demonstrating quantitative changes at
protein level under different conditions and unique
proteins are potentially useful in ultimately
understanding the cellular events that are occurring at
that time. Similarly, a comparison of protein profiles
from unstressed and stressed organisms could lead to
the identification of proteins associated directly or
indirectly with the stress response This could be easily
explain that protein/biochemical markers are have
environment interaction, therefore protein/enzymes
exclusively found in certain genotypes could able to
express in certain environmental conditions (Ei-Akkad
et al., 2002; Shehata et al., 2004; Rani et al., 2007;
Morojele et al., 2010; Metwali et al., 2011). The
detected variation could be used to provide useful
information on individual enzymes or transporters,
activity as well as modification of structural protein,
protein-protein interactions and stress dependent
protein movement and can be used to classify adapted
cultivars to improve the efficiency of wheat breeding
programmes Nevertheless, it could be concluded that
seed storage protein profiles could be useful markers
in cultivar identification, pedigree analysis,
registration of new varieties, and in the
characterization of genetic diversity and classification
of adapted cultivars, thereby improving the efficiency
of wheat breeding programs in cultivar development.
