Download or read book Evaluation of Spot Blotch Resistance in Spring Wheat Germplasm written by Manoj Kumar and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation on wheat was conducted with the objective to study variability for spot blotch resistance caused by B. sorokiniana in the wheat germplasm lines and to find out the distribution of resistance across various height and maturity groups. Observations were recorded for disease severity (%) as well as using 0-9 scale. Disease was rated three times i.e. at growth stages 69, 77 and 83 (Zadoks et.al.1974) to calculate AUDPC. Plant height, days to maturity and test weight was also recorded for each genotype. A wide variability for resistance to spot blotch was observed in the wheat lines screened.15 lines were found to have resistant. The proportion of moderately resistant, moderately susceptible and susceptible lines were 47%, 43% and 6% respectively.The useful resistant lines having dwarf stature and early days to maturity were 15. These lines can be exploited in crossing programme to developing spot blotch resistant early maturing lines suited to rice wheat cropping system of NEPZ.Differential reaction was also observed in same line that supported the idea of independent gene control.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes how genomics has revolutionized our understanding of agriculturally important plant-associated fungi. It illustrates some fundamental discoveries about these eukaryotic microbes with regard to the overall structure of their genomes, their lifestyles and the molecular mechanisms that form the basis of their interactions with plants. Genomics has provided new insights into fungal lifestyles and led to practical advances in plant breeding and crop protection, such as predictions about the spread and evolution of new pathogens. This volume focuses on fungi that are important cereal and other monocot plant pathogens and includes: Pyrenophora tritici-repentis, Cochliobolus sp., Colletotrichum sp., Fusarium graminearum, Mycosphaerella graminicola and Mycosphaerella fijiensis, Magnaporthe oryzae, Blumeria graminis and Puccinia graminis.

Download or read book Crop Improvement written by Khalid Rehman Hakeem and published by Springer Science & Business Media. This book was released on 2013-06-13 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The improvement of crop species has been a basic pursuit since cultivation began thousands of years ago. To feed an ever increasing world population will require a great increase in food production. Wheat, corn, rice, potato and few others are expected to lead as the most important crops in the world. Enormous efforts are made all over the world to document as well as use these resources. Everybody knows that the introgression of genes in wheat provided the foundation for the “Green Revolution”. Later also demonstrated the great impact that genetic resources have on production. Several factors are contributing to high plant performance under different environmental conditions, therefore an effective and complementary use of all available technological tools and resources is needed to meet the challenge.
Download or read book Molecular Breeding for Sustainable Crop Improvement written by Vijay Rani Rajpal and published by Springer. This book was released on 2016-02-02 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world population is estimated to reach to more than 10 billion by the year 2050. These projections pose a challenging situation for the agricultural scientists to increase crops productivity to meet the growing food demands. The unavailability and/or inaccessibility to appropriate gene pools with desired traits required to carry out genetic improvement of various crop species make this task formidable for the plant breeders. Incidentally, most of the desired genes reside in the wild genetic relatives of the crop species. Therefore, exploration and characterization of wild genetic resources of important crop species is vital for the efficient utilization of these gene pools for sustainable genetic improvements to assure food security. Further, understanding the myriad complexities of genic and genomic interactions among species, more particularly of wild relatives of crop species and/or phylogenetically distant germplasm, can provide the necessary inputs to increase the effectiveness of genetic improvement through traditional and/or genetic engineering methods. This book provides comprehensive and latest insights on the evolutionary genesis of diversity, access and its utilization in the evolution of various crop species. A comprehensive account of various crops, origin, exploitation of the primary, secondary and tertiary gene pools through breeding, biosystematical, cytogenetical and molecular phylogenetical relationships, and genetic enhancement through biotechnological interventions among others have been provided as the necessary underpinnings to consolidate information on the effective and sustainable utilization of the related genetic resources. The book stresses upon the importance of wild germplasm exploration, characterization and exploitation in the assimilation of important crop species. The book is especially intended for students and scientists working on the genetic improvement of crop species. Plant Breeders, Geneticists, Taxonomists, Molecular Biologists and Plant Biotechnologists working on crop species are going to find this book very useful.
Download or read book Advances in Wheat Genetics From Genome to Field written by Yasunari Ogihara and published by Springer. This book was released on 2015-09-15 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings is a collection of 46 selected papers that were presented at the 12th International Wheat Genetics Symposium (IWGS). Since the launch of the wheat genome sequencing project in 2005, the arrival of draft genome sequences has marked a new era in wheat genetics and genomics, catalyzing rapid advancement in the field. This book provides a comprehensive review of the forefront of wheat research, across various important topics such as germplasm and genetic diversity, cytogenetics and allopolyploid evolution, genome sequencing, structural and functional genomics, gene function and molecular biology, biotic stress, abiotic stress, grain quality, and classical and molecular breeding. Following an introduction, 9 parts of the book are dedicated to each of these topics. A final, 11th part entitled “Toward Sustainable Wheat Production” contains 7 excellent papers that were presented in the 12th IWGS Special Session supported by the OECD. With rapid population growth and radical climate changes, the world faces a global food crisis and is in need of another Green Revolution to boost yields of wheat and other widely grown staple crops. Although this book focuses on wheat, many of the newly developed techniques and results presented here can be applied to other plant species with large and complex genomes. As such, this volume is highly recommended for all students and researchers in wheat sciences and related plant sciences and for those who are interested in stable food production and food security.

Available in PDF, EPUB and Kindle. Book excerpt: Triticale's days as a scientific curiosity are definitely over. Its wide acceptance as a feed, grain or forage crop, or for baking and malting, plus its high yields under marginal or stress conditions have made it an economically important crop in countries such as Poland, Germany, Australia, Portugal, Brazil, Morocco and China. This publication contains selected, reviewed, and up-to-date papers presented at the Third International Triticale Symposium held in Lisbon, Portugal, by the International Triticale Association and EUCARPIA. Among the broad spectrum of subjects addressed in these presentations are cytogenetics, biotechnology, genetic resources, breeding, agronomic practices and diseases. Also included are triticale's food, feed and forage uses, as well as its marketing processes. In a world of increasing population and decreasing agricultural resources, triticale offers a genuine solution for increasing land utilization and grain production.
