GGE Biplot Analysis:
A Graphical Tool for Breeders, Geneticists
and Agronomists

by Weikai Yan
and Manjit S. Kang


  • Includes over 160 figures to enhance visualization and interpretation of a biplot based on various types of two-way data
  • Provides a holistic picture of MET data analysis
  • Details biplot analysis of genotype by trait data and shows how a biplot can help physiologists to achieve a systems understanding of the research subject and help breeders in selecting superior varieties/parents
  • Presents a new and easily understood method of QTL identification
  • Contains a new methodology for diallel data analysis
  • Gives a detailed description of biplot analysis of host-by-pathogen interaction
  • Supplies a comprehensive but succinct treatment of genotype-by-environment interaction and shows how GGE biplot methodology fits in

GGE Biplot Analysis: A Graphical Tool for Breeders, Geneticists, and Agronomists introduces the theory of the GGE biplot methodology and describes its applications in visual analysis of multi-environment trial (MET) data and other types of research data.

Part I presents a comprehensive but succinct treatment of genotype-by-environment (G x E) interaction in order to provide an overall picture of the entire G x E issue and to show how GGE biplot methodology fits in. Part II describes and demonstrates the numerous utilities of a GGE biplot in visualizing MET data. Part III describes the "GGE biplot" software and extends its application to the analysis of genotype by trait data, QTL mapping data, diallel cross data, and host by pathogen data.

Altogether, this book demonstrates that the GGE biplot methodology is a superior data-visualization tool and allows the researcher to graphically extract and utilize the information from MET data and other types of two-way data to the fullest extent.

GGE Biplot Analysis makes this useful technology accessible on a wider scale to plant and animal breeders, geneticists, agronomists, ecologists, and students in these and other related research areas. The information presented here will greatly enhance researchers' ability to understand their data and will make a significant contribution toward helping to meet the challenges of food production and food security that currently face the world.
