Sorghum Genetic Enhancement: Research Process, Dissemination and Impacts uri icon


  • This volume covers 32 years of sorghum research across ICRISAT in partnership wi th NARS in Asia, Africa andLatin America and gives insights on the many facets of the research process, dissemination and impacts. The volumewas completed through close collaboration among biological, natural and social scientists. The chapters documentthe f low of ICRISAT sorghum germplasm across regions and the genetic enhancement research process inpartnership wi t h NARS. It elaborates on ICRISAT's contribution to NARS breeding programs through capacitybuilding and the supply of useful germplasm, breeding materials, hybrid parents and cultivars. It assesses the impactsof ICRISAT-NARS partnerships in genetic enhancement research on sorghum.The contents include an introduction to the crop, trends in global sorghum production; conservation, utilizationand distribution of sorghum germplasm; research-for-development targets; research processes and strategies in Asia,Africa and Latin America, its outputs and contributions to public and private sector institutions; applications of newtools, regional breeding and market-oriented needs of sorghum. Wi th the ultimate aim of increasing sorghumproduction worldwide, ICRISAT has readily made available its germplasm to NARS of developing and developedcountries. Since NARS evaluation and selection of materials has led to the incorporation of ICRISAT germplasminto varieties released and grown in farmers' field, this book assessed the value of the germplasm to NARS and theseed sector. A systematic documentation and analysis of the use of ICRISAT germplasm is undertaken forunderstanding the role of its germplasm products in varietal development worldwide. Mechanisms to increase theefficiency of genetic enhancement research are explored through a better understanding of past activities and theirimpact on the development of new cultivars by ICRISAT and its partners. This facilitates exploitation of the wor ldgermplasm base and helps identify means of achieving greater utility.Several chapters dealt wi th research partnerships and technology exchange, adoption of improved cultivarsand lessons learned f rom adoption studies as wel l as critical factors influencing the uptake process. Importantdimensions of the impacts of sorghum research are highlighted. Research benefits were measured in terms ofincrease in yields, reduction in per uni t cost of production, increase in stability in sorghum yield and improvedfood security. The nature, extent and determinants of sorghum research spillover effects across continents andagro-ecological zones were also examined and quantified. The concluding chapter presents future directions forpartnership and a research strategy for sorghum research-for-development, suggesting new and innovativepartnerships among all players (ICRISAT, NARS, public- and private-seed sectors and NGOs ) . This book servesas a valuable resource and wi l l be of significant interest to those working in plant breeding, crop science andagricultural economics
