Biometrical genetics forms the backbone of modern crop improvement. Plant breeders rely heavily on quantitative methods to understand gene action, estimate heritability, and select superior genotypes. One of the most definitive and widely referenced texts on this subject is "Statistical and Biometrical Techniques in Plant Breeding" by Jawahar R. Sharma.
statistics measure genetic divergence among populations or genotypes. By grouping genotypes into distinct clusters, breeders can deliberately cross genetically distant parents to maximize heterosis (hybrid vigor) and generate transgressive segregants.

The book's authority comes from its author. was a distinguished Indian plant breeder, geneticist, and researcher with a career spanning some of the nation's premier agricultural institutes. Born in Varanasi in 1942, he dedicated his life to the science of plant improvement. His extensive career included roles at the Punjab Agricultural University, the prestigious Indian Agricultural Research Institute (IARI) , and the Central Institute of Medicinal and Aromatic Plants (CIMAP) in Lucknow, where he eventually rose to the position of Director-grade scientist.
Genotype-by-Environment Interaction (GEI) is a major challenge in plant breeding. A genotype that performs well in one location might fail in another. Sharma’s book details classical stability models used to identify widely adapted or specifically adapted crop varieties: For more details
The book serves as an encyclopedia of biometrical models:
Jawahar R. Sharma's "Statistical and Biometrical Techniques in Plant Breeding" serves as a foundational text for bridging complex mathematical theory with practical crop improvement, focusing on genetic variability, experimental design, and multivariate analysis. The work provides essential frameworks for analyzing genotype-by-environment interactions, gene action, and selection methods to enhance breeding efficiency.
