Download or read book The Relationship Between Phenotypic Values in Male sterile Sorghum Parents and in Their F1 Hybrids written by R.R. Muyco and published by . This book was released on 1985 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirty grain sorghum (Sorghum bicolor (L.) Moench) hybrids were generated by crossing each of ten cytoplasmic male-sterile lines with three diverse tester lines. The parents and their hybrids were grown in four replications at the Central Experiment Station during the 1983-1984 dry season. The study aimed to determine the relationship between the male-sterile parents and their F1 hybrids, identify the appropriate male testers for evaluating the combinig ability of male-seterile parents, and identify sorghum hybrids with potential for comercial use. Agronomic characters measured included grain yield, days to 50% bloming, plant height, 1000-seed weight and average number of seeds per head. The analysis of vriance showed that parental lines as well as their F1 hybrids were all significantly different for the five characters measured. Parental lines contributed a major portion of the total variation. Grain yield was found to be the most heterotic character. Male-sterilie parents were highly correlated with their F1 hybrids for days to 50% blooming, plant height and average number of seeds per head. But F1 hybrids approached their male parent in days to 50% blooming and were generally taller than their parental lines. Correlation values for grain yield and 1000-seed weight were positive but not high enough to be significant. The top yielding male-sterilie lines were positive for general combining ability effects for yield, days to 50% blooming, and average number of seeds per head. These lines were ATX622, (...).

Download or read book Sorghum Molecular Breeding written by R. Madhusudhana and published by Springer. This book was released on 2015-08-20 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date overview of international research work on sorghum. Its comprehensive coverage of our current understanding of transgenic development in sorghum and the strategies that are being applied in molecular breeding make this book unique. Important areas such as genetic diversity, QTL mapping, heterosis prediction, genomic and bioinformatics resources, post-genome sequencing developments, molecular markers development using bioinformatics tools, genetic transformation and transgenic research are also addressed. The availability of the genome sequence along with other recent developments in sequencing and genotyping technologies has resulted in considerable advances in the area of sorghum genomics. These in turn have led to the generation of a large number of DNA-based markers and resulted in the identification and fine mapping of QTL associated with grain yield, its component traits, biotic and abiotic stress tolerance as well as grain quality traits in sorghum. Though a large volume of information has accumulated over the years, especially following the sequencing of the sorghum genome, until now it was not available in a single reference resource. This book fills that gap by documenting advances in the genomics and transgenic research in sorghum and presenting critical reviews and future prospects. “Sorghum Molecular Breeding” is an essential guide for students, researchers and managers who are involved in the area of molecular breeding and transgenic research in sorghum and plant biologists in general.

This book was released on 2007-11-04 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have taught plant molecular biology and biotechnology at the undergraduate and graduate level for over 20 years. In the past few decades, the field of plant organelle molecular biology and biotechnology has made immense strides. From the green revolution to golden rice, plant organelles have revolutionized agriculture. Given the exponential growth in research, the problem of finding appropriate textbooks for courses in plant biotechnology and molecular biology has become a major challenge. After years of handing out photocopies of various journal articles and reviews scattered through out the print and electronic media, a serendipitous meeting occurred at the 2002 IATPC World Congress held in Orlando, Florida. After my talk and evaluating several posters presented by investigators from my laboratory, Dr. Jacco Flipsen, Publishing Manager of Kluwer Publishers asked me whether I would consider editing a book on Plant Organelles. I accepted this challenge, after months of deliberations, primarily because I was unsuccessful in finding a text book in this area for many years. I signed the contract with Kluwer in March 2003 with a promise to deliver a camera-ready textbook on July 1, 2004. Given the short deadline and the complexity of the task, I quickly realized this task would need a co-editor. Dr. Christine Chase was the first scientist who came to my mind because of her expertise in plant mitochondria, and she readily agreed to work with me on this book.

Download or read book Drought phenotyping in crops From theory to practice written by Philippe Monneveux and published by Frontiers E-books. This book was released on 2014-02-12 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This topic is a unique attempt to simultaneously tackle theoretical and practical aspects in drought phenotyping, through both crop-specific and cross-cutting approaches. It is designed for – and will be of use to – practitioners and postgraduate students in plant science, who are grappling with the challenging task of evaluating germplasm performance under different water regimes. In Part I, different methodologies are presented for accurately characterising environmental conditions, implementing trials, and capturing and analysing the information this generates, regardless of the crop. Part II presents the state-of-art in research on adaptation to drought, and recommends specific protocols to measure different traits in major food crops (focusing on particular cereals, legumes and clonal crops). The topic is part of the CGIAR Generation Challenge Programme’s efforts to disseminate crop research information, tools and protocols, for improving characterisation of environments and phenotyping conditions. The goal is to enhance expertise in testing locations, and to stimulate the development and use of traits related to drought tolerance, as well as innovative protocols for crop characterisation and breeding.
Download or read book Pollination Mechanisms Reproduction and Plant Breeding written by R. Frankel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: view than its own proper males should fecundate each blossom." ANDREW KNIGHT Philosophical Transactions, 1799 Pollination mechanisms and reproduction have a decisive bearing upon rational procedures in plant breeding and crop production. This book intends to furnish' under one cover an integrated botanical, genetical and breeding-methodologi cal treatment of the reproductive biology of spermatophytes mainly angiosperms; it is based on an advanced topical course in plant breeding taught at the Hebrew University of Jerusa lem. We have tried to present a coverage which is concise, but as comprehensive as possible, of the pollination mechanism and modes of reproduction of higher plants, and to illustrate topics, whenever practicable, by examples from cultivated plants. Nevertheless, some relevant publications may have escaped our attention or may not be mentioned because of various limitations. The book is organized into three parts. The first part starts with an evaluation of the significance of the different pollination mechanisms for plant breeding and crop produc tion, describes modes of reproduction in higher plants and discusses ecology and dynamics of pollination. The second part is devoted to crops propagated by self pollination and describes specific breeding procedures for such crops. The third part details sexual reproduction in higher plants and handles three mechanisms involved in the prevention of self pollination and their utilization in plant breeding: sex expres sion, incompatibility, and male sterility.

Available in PDF, EPUB and Kindle. Book excerpt: Horticultural Plant Breeding is a complete and comprehensive resource for the development of new cultivars or clones of horticultural crops. It covers the basic theories that underpin plant breeding and applies Mendelian, quantitative and population inheritance practices in smaller populations where the individual plant has high value. Specific traditional breeding methods are also covered, with an emphasis on how these methods are adapted for horticultural species. In addition, the integration of biotechnologies with traditional breeding methodologies is explored, with an emphasis on specific applications for fruits, vegetables and ornamental crop species. Presented in focused sections, Horticultural Plant Breeding addresses historical perspectives and context, and genetics as a critical foundation of plant breeding. It highlights treatments of the various components of breeding programs, such as breeding objectives, germplasm, population engineering, mating systems, enhanced selection methods, established breeding methods applicable to inbreeding and outcrossing situations, and post-breeding activities. Provides a complete and comprehensive resource for those involved in the development of new cultivars or clones of horticultural crops Guides readers to the most appropriate breeding strategy including potential integration of traditional and biotechnology strategies that will best achieve a cost-effective outcome Will include access to 20 narrated slide sets to facilitate additional understanding
