Download or read book Broadening the Genetic Base of Grain Cereals written by Mohar Singh and published by Springer. This book was released on 2016-09-13 with total page 282 pages. 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.

Download or read book Rice Planthoppers written by Kong Luen Heong and published by Springer. This book was released on 2014-10-23 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses planthopper pests of rice. These insects are one of the most destructive pests, threatening food security around the world. The historical development of the rice planthopper problem shows that they are secondary pests and single-discipline control tactics or strategies were not able to manage them, and instead caused frequent resurgences. This book not only presents new approaches to this persistent problem, but also new ecological methods, new perspectives on the effect of pesticide marketing, insights into developing resistant varieties and structural reforms in pest management. Integrating biological, ecological, economic and sociological aspects, it clearly presents the latest information on newly developed strategies for managing this pest. Dr. K. L. Heong is the principal scientist and insect ecologist at the International Rice Research Institute, Philippines. He has been researching rice planthoppers for more than 30 years. Dr. Heong is a fellow of the Third World Academy of Science and the Academy of Sciences, Malaysia. Professor Jia-an Cheng is an insect ecologist who has been studying rice planthoppers for about 50 years. He is a professor at Zhejiang University, China. Professor M.M. Escalada works at Visayas State University.

This book was released on 1981 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanisms of resistance involved in moderately resistant rice varieties to the browh planthopper, Nilaparvata lugens were studied. Moderate resistance is found quantitatively expressed and polygenically controlled with minor genes having a small, cumulative effect. Minor gene recombination occurred in the F2 and F3 accumulatively.

Download or read book Return to Resistance written by Raoul A. Robinson and published by IDRC. This book was released on 1996 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.
