Molecular Marker Based Classification of Crop Genotypes

Introduction Information about genetic diversity is an invaluable aid in crop improvement programmes. In literature, a large number of methods are available to analyze genetic diversity in populations. To have an idea on genetic diversity, much attention has to be given on multivariate statistical techniques applied in genetic data. The data often involve a number of numerical measurements and combinations of different types of variables. Different data sets like pedigree data, passport data, biochemical data obtained from isozyme analysis, and, recently, DNA-based molecular marker data. In this lecture, a brief discussion will be made on clustering techniques applied on molecular marker data of crop genotypes. For more details on this topic one may refer to Mohamadi and Prasanna (2003).
