In early generation trials (F2, F3), you don’t have enough seed for replicated checks. Sharma explains Augmented Randomized Complete Block Design—a statistical lifesaver that allows you to adjust unreplicated new lines using replicated checks.
If you absolutely cannot find Sharma’s PDF, these textbooks cover 90% of the same material and are easier to find legally:

is a highly regarded text-cum-reference book for graduate students and researchers in agricultural sciences. Authored by Dr. Jawahar R. Sharma, a former Director at the Central Institute of Medicinal and Aromatic Plants (CIMAP), the book serves as a bridge for biologists and geneticists who may lack deep mathematical training but need to apply rigorous statistical tools to their research. Key Strengths and Coverage
The book is organized into 25 chapters across five distinct sections, making it a comprehensive "ready-reckoner" for plant breeding data management:
Section 1: Foundations & Field Designs: Covers general biometrical parameters and standard field designs.
Section 2: Multivariate Analysis: Focuses on genetic divergence through models like D2cap D squared statistics. Falconer & Mackay | Heritability and Genetic advance
Section 3: G x E Interaction: Explores genotype-by-environment stability parameters.
Section 4: Gene Action: Details variance components and the nature of gene action.
Section 5: Selection & Mutation: Analyzes parameters specifically related to mutation experiments and selection response. User & Expert Feedback
Practicality: Reviewers from platforms like Amazon India and Goodreads highlight the inclusion of solved practical examples in each chapter as its most useful feature. Resources like the one you're looking for are
Accessibility: The book is praised for simplifying complex biometrical notations into language easily grasped by those without a heavy statistical background.
Academic Utility: It is widely recommended for students in Indian agricultural universities preparing for research and data analysis. Areas for Improvement
Experts in the Indian Journal of Genetics and Plant Breeding have noted that while the book is extensive, future editions could benefit from more detailed treatments of Discriminant Function for Plant Selection and elaborated examples of skewness and kurtosis in mutation populations.
Note on PDF Availability: While many academic platforms like ResearchGate host related research papers and slides on biometrical techniques, the full textbook is a copyrighted work published by New Age International and is primarily available in hardcover or paperback.
