Download or read book The 1953 Iowa Corn Yield Test written by Joseph Lee Robinson and published by . This book was released on 1954 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 1953 we tested 229 corn hybrids in the Iowa Corn Yield test. Each hybrid was tested at a minimum of three locations. The division of the state into districts and sections is shown on the map. Seven characteristics of each hybrid were recorded and summarized. These included yield, stand, moisture, root and stalk lodging, ear height and dropped ears. Each hybrid was ranked by a performance score based on yield, moisture and resistance to lodging and dropped ears. You will find records in the tables showing how each hybrid performed for the above characteristics. An index listing the hybrids tested in 1953 is given in the back of this bulletin. A majority of the entries in the test were made by commercial hybrid corn companies. The Iowa Crop Improvement Association also entered 10 widely grown hybrids in each section as determined by a survey of farmers. The purpose of the Iowa Corn Yield Test is to determine the performance of hybrids. It is not a contest and should not be confused with the 5-acre Iowa Master Corn Growers Contest." -- Foreword, p. [2]

Book excerpt: "This bulletin reports the results of the 1952 Iowa Corn Yield Test in which the performance of 219 different corn hybrids was compared. The state was divided into four sections, each of which was subdivided into three districts. A test field was planted in each district. Each hybrid entry was tested in all three districts of a section. The map shows how we divided the state into sections and districts and the approximate location of the farm where the hybrids were compared. Any producer of hybrid corn seed was eligible to enter his corn in the test. The widely grown hybrids in each section also were entered by the Iowa Crop Improvement Association. In the back of the bulletin you will find an index listing hybrids tested in 1952. The index also indicates whether the hybrid is a single, three-way, double or multiple cross." -- p. [858]

Download or read book Managing Cover Crops Profitably 3rd Ed written by Andy Clark and published by DIANE Publishing. This book was released on 2008-07 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

This book was released on 2022-09-15 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genomic selection (GS) has been the most prominent topic in breeding science in the last two decades. The continued interest is promoted by its huge potential impact on the efficiency of breeding. Predicting a breeding value based on molecular markers and phenotypic values of relatives may be used to manipulate three parameters of the breeder's equation. First, the accuracy of the selection may be improved by predicting the genetic value more reliably when considering the records of relatives and the realized genomic relationship. Secondly, genotyping and predicting may be more cost effective than comprehensive phenotyping. Resources can instead be allocated to increasing population sizes and selection intensity. The third, probably most important factor, is time. As shown in dairy cattle breeding, reducing cycle time by crossing selection candidates earlier may have the strongest impact on selection gain. Many different prediction models have been used, and different ways of using predicted values in a breeding program have been explored. We would like to address the questions: i. How did GS change breeding schemes of different crops in the last 20 years? ii. What was the impact on realized selection gain? iii. What would be the best structure of a crop-specific breeding scheme to exploit the full potential of GS? iv. What is the potential of hybrid prediction, epistasis effect models, deep learning methods and other extensions of the standard prediction of additive effects? v. What are the long-term effects of GS? vi. Can predictive breeding approaches also be used to harness genetic resources from germplasm banks in a more efficient way to adapt current germplasm to new environmental challenges? This Research Topic welcomes submissions of Original Research papers, Opinions, Perspectives, Reviews, and Mini-Reviews related to these themes: 1. Genomic selection: statistical methodology 2. The (optimal) use of GS in breeding schemes 3. Practical experiences with GS (selection gain, long-term effects, negative side effects) 4. Predictive approaches to harness genetic resources Concerning point 1): If an original research paper compares different methods empirically without theoretical considerations on when one or the other method should be better, the methods should be compared with at least five different data sets. The data sets should differ either in crop, genotyping method or its source, for instance from a breeding program or gene bank accessions. Concerning point 2): Manuscripts addressing the use of GS in breeding schemes should illustrate breeding schemes that are run in practice. General ideas about schemes that may be run in the future may be considered as 'Perspective' articles.
