The book surveys the history and practice of corn breeding, weighing methods from mass selection to crossing varieties. It explains how hybrids can produce larger yields in the first generation and why maintaining pure parent stocks matters. Grounded in early 20th‑century research and agricultural trials, this edition clarifies practical approaches for farmers and breeders alike.

How mass selection and ear-to-row methods compare for improving yield

Why hybrid vigor shows up in first-generation crosses and how to use it

Ways to maintain hybrid seed and manage parent varieties

When varietal hybrids are most effective and how crosses between varieties work

Ideal for readers of agricultural science, plant breeding, and those interested in practical corn improvement.

We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
