MOLECULAR MARKERS IN WHEAT

Abstract

The progress made in DNA markers technology has been tremendous and exciting. DNA markers have provided valuable tools in various analysis ranging from polygenetic analysis to the positional cloning of genes. The development of high density molecular maps which has been facilitated by the PCR-based markers have made the mapping of almost any trait possible. The size and structure of the wheat genome makes it one of the most complex crop species for genetic analysis. The development of molecular technique for
genetic analysis, in particular the use of molecular markers to monitor DNA sequence variation between varieties, and races, and wild relatives of wheat and related grass species, has led to a dramatic expansion in our understanding the structure and behavior of wheat genome.
