Summary

This chapter provides an overview of genetic diversity and variation and how to measure this when studying plant genetic resources. It also describes the use of DNA markers for assessing polymorphism, studying diversity and revealing trait associations relevant for searching variation of target characters in plant breeding. The goal of this chapter is therefore to highlight various methods for analyzing the range of genetic diversity and of character variation to facilitate their further use in plant breeding. The information given herein will allow to understand genetic diversity, gene polymorphism and genetic variation; assess how various techniques – based on population and quantitative genetics – are used for assessing genetic diversity and trait variation in plant germplasm; and determine how the data generated can be effectively analyzed.
