ABSTRACT
Plant
breeding and molecular maker assisted selection (MAS) approaches have been used
to produce plants carrying the desired traits. Molecular marker based breeding
strategies have been used to accelerate the process of moving trait genes into
high-yielding germplasm for commercialization. These products are being tested
for applications in food, feed and industrial markets. Clearly, DNA based
marker techniques are not a replacement for classical breeding and selection
techniques. Rather they have become a powerful accelerating tool to improve the
rate of selection for quality traits. The specificity of molecular monitoring
provides the confidence in trait selection and overall cost-effectiveness for
improvement for these complex quality traits.
