Marker assisted selection
Marker-assisted selection (MAS) is the process
of using morphological, biochemical, or DNA markers
as indirect selection criteria for selecting agriculturally
important traits in crop breeding. This process is used
to improve the effectiveness or efficiency of selection
for the traits of interest in breeding programs. With the
recent advances in marker technology, including high-
throughput genotyping of plants, together with the
development
of
nested
association
mapping
populations, it is expected that the utility of MAS for
breeding for stress tolerance traits will increase.
Salt
tolerance is a complex quantitative trait that is
controlled by many genes each of which have small
effect. It is impossible to elucidate its genetic control
through a single gene-based studies. Genetic basis of
salt tolerance in various plants have been explained by
QTL (quantitative trait loci) analyses. Marker assisted
selection is a promising approach for indirect selection
of salt tolerant genotypes. Proteomic techniques can
be used as a tool to identify proteins linked with salt
resistance.
