The Book Presents A Comprehensive Account Of The Concept And Genesis Of Diverse Biometrical/Statistical Models As Applied To Plant Breeding Experiments Under Different Situations. Generation And Statistical Treatment Of Data; Presentation, Interpretation And Inferences Of Results; Merits, Demerits And Situations Of Applicability Of Models Are All Explicated For Their Adequate And Appropriate Usage In Plant Breeding. The Whole Volume Comprising 25 Chapters Has Been Zipped Into Five Sections Elucidating; General Statistical/Biometrical Parameters And Field Designs (Chapters 1-4), Multivariate Analysis Of Genetic Divergence (Chapters 6-7), Genotype X Environment Interaction And Stability Parameters (Chapters 8-10), Analysis Of Nature Of Gene Action And Variance Components (Chapters 11 -23), And Lastly The Unique Analysis Of Statistical And Genetical Parameters Related To Selection And Mutation Experiments (Chapters 24-25) In Plant Breeding. Simplification Of The Bewildering Complexities Of Biometrical Notations And Procedures In A Language Which Could Easily Be Grasped By Biologists/Geneticists Having Little Or No Statistical Background Is The Hallmark Of The Treatise. Like A Ready-Reckoner, This Work Offers An Efficient Key To Plant Breeding Data-Management For Both Students And Professional Plant Breeders Alike In Pursuit Of Their Research Goals.

Alternate approaches for the exploitation of heterosis and population improvement have been elaborated with the help of schematic diagrams.

The book entitled "Principles of Biometrical Genetics" is prepared to serve as a text book for M.Sc. (Ag.) students. The book is written in simple language and even complex terms have been reduced for easy understanding. Hope this textbook would be useful for post graduate students, teachers and researchers engaged in the field of Genetics and Plant Breeding.
