Available in PDF, EPUB and Kindle. Book excerpt: Sheat blight (ShB) is considered as one of the serious diseases of rice in Asian countries and the USA. The increase in ShB incidence is largely due to changes in the rice cultivation methods as well as in the use of early-maturing, semi-dwarf, high-yielding and N-responsive cultivars. Against this background, this monographic study is aimed primarily presenting the status of our knowledge by compiling the literature available as well as the author s own experience on rice diseases over three decades. The book is meant primarily for the graduate students, rice pathologists and extension workers. This compendium should not only stimulated further research but also will be used for ShB management. It traces the history of the disease, the casual agents, its nomenclature, taxonomy, morphology, physiology, variability, histopathology and ultra structure. It is profusely illustrated with excellent plates and number of tables which project the current status in a better way. Also information has been given on the disease management by induced resistance as well as biocontrol and the future resistance as well as biocontrol and the future perspectives on this important rice disease.

Book excerpt: Rice being the most important cereal of not only in India but in most of the Asian and African countries and also the most important cereal second to wheat only. In India the average productivity of rice is approximately 3.4 t/h which is much below than its highest productivity. The major constraints of rice production are different stresses which include both biotic and abiotic stresses. Out of the biotic factors different diseases caused by fungi, bacteria and viruses are major. The rice suffers from different fungal diseases like blast, sheath blight, brown spot, sheath rot, false smut, seedling blight, bakanae etc. Sheath blight (ShB) of rice has emerged as a serious threat for rice cultivation for the Indian subcontinent. The introduction of semi dwarf high yielding varieties of rice has brought evolution in rice production in India but also it has invited several problems along with it like some minor diseases have emerged as a major one. The sheath blight (ShB), caused by Rhizoctonia solani (Kuhn) (perfect stage Thanatephorus cucumeris), which was once a minor disease has turned to be a serious threat to rice cultivation in mainly tropical countries. The estimated yield loss due to this disease is 5.2 to 50 percent depending upon the environmental conditions. The disease was first identified in Japan and subsequently spread to various parts of the world. The major problem of the disease is that the causal organism is polyphagous in nature and formation of new anastomosis group in nature leading to new virulent strains. There are many reasons behind the difficulties in controlling this disease including wide host range of the pathogen and its capability to survive for longer period of time as thick walled sclerotia in the soil as well as its high genetic variability. The pathogen can be effectively controlled by fungicide only which shows negative impact on environment.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rice blast disease caused by the fungus Magnaporthe oryzae and rice sheath blight disease caused by the fungus Rhizoctonia solani are two major hurdles for stable rice production worldwide. Presently, fungicides are still needed to manage these two devastating fungal pathogens. After two decades of research efforts, a toolbox has been assembled with the following components: (1) insight into pathogen genomic identity and pathogen avirulence (AVR) genes that can be used to enhance plant breeding; (2) new mapping populations and germplasm and genetic stocks that can be used as starting materials to identify effective host resistance (R) genes; (3) user-friendly disease evaluation methods that can be used to accelerate the identification and utilization of R genes; (4) validated effective R genes that are readily available for improving genetic resistance; (5) host genetic markers that can be used to accelerate the development of new resistant germplasms/cultivars; and (6) an improved understanding of resistance mechanisms that can facilitate the engineering of resistance in commercial varieties. Appropriate employment of these tools in breeding and crop protection will reduce production costs and create an environmentally benign, sustainable rice production system.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers comprehensive coverage of important grain cereals including their origin and distribution, crop gene pool, level of diversity, production constraints, traits of importance for genetic base widening, crop improvement methodologies, genome mapping, genomics for breeding, and future strategies. The chapters, contributed by eminent crop researchers from around the world, provide rare insights into the crop-specific constraints and prospects drawing from their substantial experience. As such, the book offers an essential source of information for grain cereals scientists, teachers, students, policy planners and developmental experts alike. Grain cereals, which comprise rice, wheat, maize, barley, oats, sorghum and millets, are members of the grass family. These crops are vital to human nutrition, thanks to their roles as staple food crops in different parts of the globe. Some of them are rich sources of carbohydrates, which provide energy, while others are important sources of minerals, vitamins and proteins, in addition to their medicinal properties. In most cereals, the existing variability among elite germplasm has been exploited to attain a desirable level of productivity. However, to make further breakthroughs in enhancing yield and improving stability in future crop cultivars, new sources of genes/alleles need to be identified in wild/weedy species and incorporated into the cultivated varieties. Though there have been many publications on various aspects of grain cereal improvement in the recent past, to date this essential information has remained scattered among different periodicals.
