This book provides a fresh, updated perspective of the current status and perspectives in genetic improvement of a diverse array of tropical crops. The first part covers aspects which are relevant across crops, namely how to maximize the use of genetic information through modern bioinformatic approaches and how to use statistics as a tool to sustain increased genetic gains and breeding efficiency. The second part of the book provides an updated view of some seed-propagated crops, such as rice, maize and oil palm, as well as crops propagated through vegetative means such as sweet potato, cassava, banana and sugarcane. Each chapter addresses the main breeding objectives, markets served, current breeding approaches, biotechnology, genetic progress observed, and in addition a glimpse into the future for each of these selected and important tropical crops.

It is perhaps appropriati that the relation between genetics and crop-plant improvement should be the subject of a lecture in this School, since it was here that some of the first attepts to apply Mendelian theory to practical plant breeding were made, and theory to practical plant breendig were made, and the School was the birthplace of famous new cropplant varieties as Yeomen and Holdfast wheats and Proctor barley. I have given notice in my title of my intention to restrict myself to tropical crops, because it is of tropical crops that I have some experience, but I hope to show that the conclusions to be drawn from their study are of general application, and that a knowledge of the genetics of tropical crops is a sound base from which to launch an incursion into the field of applied genetics temperate regions.

Learn to integrate molecular genetic techniques with traditional plant breeding methods! This comprehensive book provides the latest authoritative scientific information on improvement of both temperate and tropical crops. Crop Improvement: Challenges in the Twenty-First Century brings together expert plant breeders and geneticists to address issues related to crop adaptability and stability across environments for important food and fiber crops. It emphasizes the need to integrate molecular genetic techniques with traditional plant breeding methods to develop hardier, more productive crops. Crop Improvement includes the latest research on physiological and biochemical responses of plants to drought and heat stress, which should help breeders develop effective strategies for improving resistance to abiotic stresses. In addition, this helpful book elucidates the use of mixed models and best linear unbiased prediction. To make the book comprehensive, chapters discuss stability analysis in crop performance trials and genotype-by-environment interactions. Crop Improvement includes detailed information on breeding specific crops, including: rice tropical maize sorghum common bean sugar beet bananas and plantain cotton Crop Improvement offers both practical information and up-to-date research. It also suggests a vision of new directions and partnerships that are expected to evolve in this century. This book is an essential resource for practicing plant breeders and geneticists at universities, government agencies, and industry. It should also be of use to teachers and students engaged in crop breeding.

Maize is used in an endless list of products that are directly or indirectly related to human nutrition and food security. Maize is grown in producer farms, farmers depend on genetically improved cultivars, and maize breeders develop improved maize cultivars for farmers. Nikolai I. Vavilov defined plant breeding as plant evolution directed by man. Among crops, maize is one of the most successful examples for breeder-directed evolution. Maize is a cross-pollinated species with unique and separate male and female organs allowing techniques from both self and cross-pollinated crops to be utilized. As a consequence, a diverse set of breeding methods can be utilized for the development of various maize cultivar types for all economic conditions (e.g., improved populations, inbred lines, and their hybrids for different types of markets). Maize breeding is the science of maize cultivar development. Public investment in maize breeding from 1865 to 1996 was $3 billion (Crosbie et al., 2004) and the return on investment was $260 billion as a consequence of applied maize breeding, even without full understanding of the genetic basis of heterosis. The principles of quantitative genetics have been successfully applied by maize breeders worldwide to adapt and improve germplasm sources of cultivars for very simple traits (e.g. maize flowering) and very complex ones (e.g., grain yield). For instance, genomic efforts have isolated early-maturing genes and QTL for potential MAS but very simple and low cost phenotypic efforts have caused significant and fast genetic progress across genotypes moving elite tropical and late temperate maize northward with minimal investment. Quantitative genetics has allowed the integration of pre-breeding with cultivar development by characterizing populations genetically, adapting them to places never thought of (e.g., tropical to short-seasons), improving them by all sorts of intra- and inter-population recurrent selection methods, extracting lines with more probability of success, and exploiting inbreeding and heterosis. Quantitative genetics in maize breeding has improved the odds of developing outstanding maize cultivars from genetically broad based improved populations such as B73. The inbred-hybrid concept in maize was a public sector invention 100 years ago and it is still considered one of the greatest achievements in plant breeding. Maize hybrids grown by farmers today are still produced following this methodology and there is still no limit to genetic improvement when most genes are targeted in the breeding process. Heterotic effects are unique for each hybrid and exotic genetic materials (e.g., tropical, early maturing) carry useful alleles for complex traits not present in the B73 genome just sequenced while increasing the genetic diversity of U.S. hybrids. Breeding programs based on classical quantitative genetics and selection methods will be the basis for proving theoretical approaches on breeding plans based on molecular markers. Mating designs still offer large sample sizes when compared to QTL approaches and there is still a need to successful integration of these methods. There is a need to increase the genetic diversity of maize hybrids available in the market (e.g., there is a need to increase the number of early maturing testers in the northern U.S.). Public programs can still develop new and genetically diverse products not available in industry. However, public U.S. maize breeding programs have either been discontinued or are eroding because of decreasing state and federal funding toward basic science. Future significant genetic gains in maize are dependent on the incorporation of useful and unique genetic diversity not available in industry (e.g., NDSU EarlyGEM lines). The integration of pre-breeding methods with cultivar development should enhance future breeding efforts to maintain active public breeding programs not only adapting and improving genetically broad-based germplasm but also developing unique products and training the next generation of maize breeders producing research dissertations directly linked to breeding programs. This is especially important in areas where commercial hybrids are not locally bred. More than ever public and private institutions are encouraged to cooperate in order to share breeding rights, research goals, winter nurseries, managed stress environments, and latest technology for the benefit of producing the best possible hybrids for farmers with the least cost. We have the opportunity to link both classical and modern technology for the benefit of breeding in close cooperation with industry without the need for investing in academic labs and time (e.g., industry labs take a week vs months/years in academic labs for the same work). This volume, as part of the Handbook of Plant Breeding series, aims to increase awareness of the relative value and impact of maize breeding for food, feed, and fuel security. Without breeding programs continuously developing improved germplasm, no technology can develop improved cultivars. Quantitative Genetics in Maize Breeding presents principles and data that can be applied to maximize genetic improvement of germplasm and develop superior genotypes in different crops. The topics included should be of interest of graduate students and breeders conducting research not only on breeding and selection methods but also developing pure lines and hybrid cultivars in crop species. This volume is a unique and permanent contribution to breeders, geneticists, students, policy makers, and land-grant institutions still promoting quality research in applied plant breeding as opposed to promoting grant monies and indirect costs at any short-term cost. The book is dedicated to those who envision the development of the next generation of cultivars with less need of water and inputs, with better nutrition; and with higher percentages of exotic germplasm as well as those that pursue independent research goals before searching for funding. Scientists are encouraged to use all possible breeding methodologies available (e.g., transgenics, classical breeding, MAS, and all possible combinations could be used with specific sound long and short-term goals on mind) once germplasm is chosen making wise decisions with proven and scientifically sound technologies for assisting current breeding efforts depending on the particular trait under selection.
