Experiments in Wheat Breeding: Experimental Error in the Nursery and Variation in Nitrogen and Yield (Classic Reprint) - Softcover
Synopsis
Excerpt from Experiments in Wheat Breeding: Experimental Error in the Nursery and Variation in Nitrogen and Yield
One of the striking features of the data obtained by Dr. Lyon was the variation in nitrogen content of the kernels from different plants of wheat grown under apparently similar conditions. For example, 800 spikes of Turkey wheat were selected and half of each spike analyzed for proteid nitrogen, the lowest having only per cent while the highest contained per cent.
In 1903, 288 plants which were the progeny from 119 of the spikes analyzing above 3 per cent proteid nitrogen in 1902 were analyzed and found to vary from per cent to per cent in nitrogen content. In most of the families only a single plant was selected for analysis, but in the remainder two to six plants were selected. Even where all the plants were grown from a single parent the varia tion was quite as great.

Seller rating 4 out of 5 stars
Paperback. Condition: New. Print on Demand. This book examines the growth, nitrogen content, and yield of different varieties of wheat. The author was concerned with transmitted qualities and conducted long-term experiments in wheat breeding, drawing on data from 1902 to 1910. The author found that wheat plants of the same variety widely varied in nitrogen content and yield when grown under the same environmental conditions. This variability was not the result of genetic heritage, and therefore, unlikely to be transmitted to offspring. The author explored experimental methodology to reduce error in their experiments and increase the reliability of their results. The book details numerous experiments conducted by the author, including trials with centgeners, row plats, and small block plats. The experiments tested replication of single plants, 2-foot rows, and 16-foot rows, as well as the repetition of small blocks sown at the ordinary rate of seeding. It also includes data on experimental error in the nursery and variation in yield from check rows, repeated rows, and small block tests. The book emphasizes the challenges of conducting agricultural experiments in an environment with many uncontrollable factors and provides useful insights and strategies for reducing error in field experiments. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Seller Inventory # 9780260049988_0
