Book excerpt: Excerpt from A Professor's Story of Hybrid Corn Many students of the origin of crop plants have accepted the hypothesis of the Russian scientist, Vavilov, that the region of greatest diversity of types is usually the region of origin. Mangelsdorf and Reeves (1939, Mangelsdorf and Mangelsdorf and Smith have made extensive studies of the origin of corn, and their conclusions have been rather generally accepted, although others have different viewpoints regarding certain phases. The views of Mangelsdorf and co workers have been followed in this summary. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 2001, this is the second of two volumes published by Cambridge University Press in honour of Richard Lewontin. This second volume of essays honours the philosophical, historical and political dimensions of his work. It is fitting that the volume covers such a wide range of perspectives on modern biology, given the range of Lewontin's own contributions. He is not just a very successful practitioner of evolutionary genetics, but a rigorous critic of the practices of genetics and evolutionary biology and an articulate analyst of the social, political and economic contexts and consequences of genetic and evolutionary research. The volume begins with an essay by Lewontin on Natural History and Formalism in Evolutionary Genetics, and includes contributions by former students, post-docs, colleagues and collaborators, which cover issues ranging from the history and conceptual foundations of evolutionary biology and genetics, to the implications of human genetic diversity.

Available in PDF, EPUB and Kindle. Book excerpt: The Indian Society of Genetics and Plant Breeding was established in 1941 in recognition of the growing contribution of improved crop varieties to the country's agriculture. Scientific plant breeding had started inIndia soon after the rediscovery of Mendel's laws of heredity. The Indian Agricultural Research Institute set up in 1905 and a number of Agricultural Colleges in different parts of the country carried out some of the earliest work mostly inthe form of pure-line selections. In subsequent years, hybridization programmes in crops like wheat, rice, oilseeds, grain legumes, sugarcane and cotton yielded a large number of improved cultivars with significantly higher yields. A turning point came in the 1960s with the development of hybrids in several crops including inter-specific hybrids in cotton. And when new germplasm with dwarfing genes became available in wheat and rice from CIMMYT and IRRI, respectively,Indian plant breeders quickly incorporated these genes into the genetic background of the country's widely grown varieties with excellent grain quality and other desirable traits. This was to mark the beginning of modem agriculture in India as more and more varieties were developed, characterized by a high harvest index and response to modem farm inputs like the inorganic fertilizers . India's green revolution which has led to major surpluses offood grains and othercommodities like sugar and cotton has been made possible by the work of one of the largest groups of plant breeders working in a coordinated network.

Download or read book Quantitative Genetics in Maize Breeding written by Arnel R. Hallauer and published by Springer Science & Business Media. This book was released on 2010-09-28 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Developments in Plant Genetics and Breeding, 1A: Isozymes in Plant Genetics and Breeding, Part A focuses on the advancements in the processes, methodologies, and approaches involved in the study of isozymes, including its role in plant genetics and breeding. The selection first elaborates on the historical perspectives of plant isozymes, plant genetics, and isozyme systems to study gene regulation during development. Discussions focus on the use of isozyme and similar comparisons to study differential gene regulation, gene preservation, dissemination of cultivars, propagation of cultivars and breeding lines, and studies on the effect of viral infection and hormones on isozyme expression. The text then examines allozymes in gene dosage studies, gene mapping, and plastid isozymes. The manuscript takes a look at the genetics of mitochondrial isozymes, evolution of plant isozymes, and detection of somatic variation. Topics include evolution of isozymes in plants, generation of isozymes, glutamate dehydrogenase, glutamate-oxaloacetate transaminase, and malate dehydrogenase. The text also ponders on enzyme activity staining, isozymic variation and plant breeders' rights, genetic purity of commercial seed lots, and use of isozymes in plant disease research. The selection is a valuable reference for researchers interested in the role of isozymes in plant genetics and breeding.

Download or read book The Social Consequences And Challenges Of New Agricultural Technologies written by Gigi M Berardi and published by Routledge. This book was released on 2019-07-11 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although formal social impact assessment of changing technologies in U.S. agriculture is still in its infancy, scholars have been documenting the effects of new technology throughout the twentieth century. In this collection, Prcfessors Berardi and Geisler bring together historically relevant research and a carefully chosen cross section of contemporary work. Their review of the literature is followed by an evaluation of the effects of mechanization on labor and production, written in 1904, which provides a backdrop for papers from the 1940s and 1950s examining the mechanization of agriculture in the South, in the Midwest, and in rural areas in general. Subsequent chapters offer present-day insights on such topics as the socioeconomic consequences of automated vegetable and tobacco harvesting, center-pivot irrigation, and organic and no-till cultivation. The authors also look at compensation and adjustment programs for displaced labor, the relationship between technology and agribusiness growth, and the effectiveness of university programs that prepare students to perform social impact assessments in agriculture. The edited proceedings of a spirited roundtable discussion on new directions for the study of the social impacts of farm technology and the political economy of agriculture provide the thought-provoking conclusion to this overview of the field.
