Book Description
Semi-exotic BC1F1 testcrosses were evaluated in five Iowa environments during 1998, with average grain yields of 95.7 q ha7−1 (153.1 bu ac−1). Selected testcrosses had grain yields similar to or greater (p[Less than or equal to]0.05) than their checks. Grain moisture of selected LSC-exotic and RYD-exotic testerosses was similar to and greater, respectively, than the recurrent parent testerosses, and resistance to root and stalk lodging was similar to the checks. Results support backcross introgression to incorporate alleles from exotic sources, to maintain the agronomic traits of the recurrent parent, and to maintain or enhance the combining ability of the recurrent parent heterotic pool. Inbred lines developed in CIMMYT's hybrid program have been improved for agronomic traits, for tolerance to inbreeding, and heterotic alignment. Pre-selected exotic germplasm represents a valuable resource for widening the genetic base of temperate maize.

Book Description
Maize is an important crop and the demand for as both food and animal feed is expected to grow by 235 million tonnes between now and 2030. In many countries it will be difficult to increase the area under cultivation, so gains will have to come from increased productivity and intensification of the cropping system. This book looks at all aspects of tropical maize production from physiology, growing environments, pest and diseases, plant breeding and crop management and it is a substantial information resource necessary for the development of the crop.

Book Description
Maize is an important staple food crop worldwide. It is the third most important cereal crop after wheat and rice and is economically used for both livestock feeds and human consumption. The latest maize research has opened up new opportunities for crop improvement. This book brings together recent work and advances that have recently been made in the dynamic fields of genetic characterization, molecular breeding, genetic engineering technologies, and mapping of agronomic traits of global maize germplasm. It also provides new insights into and sheds new light regarding the current research trends and future research directions in maize. This book will provoke interest in many readers, researchers, and scientists, who can find this information useful for the advancement of their research works toward maize improvement.

Book Description
Maize (Zea mays L.) is the most important staple cereal cultivated in sub-Saharan Africa but its productivity is considerable low due to several factors. Development and deployment of maize hybrids have been reported as one of the crucial options in achieving sustainable maize production in sub-Saharan Africa. Information on the heterotic response among available genetic materials in a breeding program is valuable before commencement of any hybrid development program. Unlike the temperate germplasm, maize tropical germplasm is characterized with wide genetic base and genetic complexities and thus, proper organization of the pools, populations, varieties and inbreds that can serve as parental materials for hybrid development through identification of a distinct heterotic groups and patterns among tropical germplasm becomes very essential. This paper reviewed past research efforts at characterizing heterotic response among tropical maize genetic materials with a view to point out merits and demerits in the methods used and future direction towards achieving sustainable hybrid cultivation and enhancing food security in the sub-region.

Book Description
The book focuses on the principles and practices of tropical maize improvement with special emphasis on early and extra-early maize to feed the increasing population in Sub-Saharan Africa. It highlights the similarities and differences between results obtained in temperate regions of the world and WCA in terms of corroboration or refutation of genetic principles and theory of maize breeding. The book is expected to be of great interest to maize breeders, advanced undergraduates, graduate students, professors and research scientists in the national and international research institutes all over the world, particularly Sub-Saharan Africa. It will also serve as a useful reference for agricultural extension and technology transfer systems, Non-governmental Organizations (NGOs) and Community-Based Organizations (CBOs), seed companies and community-based seed enterprises, policy makers, and all those who are interested in generating wealth from agriculture and alleviating hunger and poverty in Sub-Saharan Africa.
