The book provides deep dives into D² statistics and partitioning variance into , Dominance , and Epistatic components. This helps breeders decide on a strategy:
In the world of crop improvement, a breeder’s intuition is powerful, but data is king. Jawahar R. Sharma’s seminal work, Statistical and Biometrical Techniques in Plant Breeding , serves as the definitive bridge between complex mathematical theory and practical field application.
High variance suggests simple selection (like mass selection) will work. The book provides deep dives into D² statistics
Before making selections, a breeder must know: Is this extra yield due to better genetics, or just better soil in that specific plot? Sharma details how to use ANOVA to partition phenotypic variance into: The heritable portion. Environmental Variance: The "noise."
Check ICAR’s e-KrishiKosh or the National Digital Library of India , which often host digitized versions of classic Indian agricultural textbooks for academic use. Conclusion Sharma details how to use ANOVA to partition
