Mutation Breeding and Efficiency Enhancing Technologies for Resistance to Striga in Cereals

Abdelbagi M. A. Ghanim is an experienced plant breeder with focus on cereal breeding and related efficiency-enhancing technologies for rain-fed and irrigated dry lands. He served as the Project Officer and Technical Coordinator of the five-year IAEA coordinated research project on mutation breeding for resistance to Striga in cereals. This was during his tenure as Plant Breeder and Geneticist at the Plant Breeding and Genetics Laboratory of the Joint FAO/IAEA Centre in Seibersdorf, Austria. Prior to this role, he served as Research Professor at Agriculture Research Corporation in Sudan. Ghanim has released and registered six varieties of wheat and cotton as main contributor and five varieties of wheat and watermelon as a collaborator. He has a PhD in Plant Breeding and Genetics from the Faculty of Agriculture, Tottori University, Japan, and MSc from the Faculty of Agriculture, University of Khartoum, Sudan. Ghanim was also a Japan Science and Technology Postdoctoral Fellow at the JapanNational Research Centre, Tsukuba.
Shoba Sivasankar has 30 years of experience leading and managing international agricultural R&D programs. She is currently the Head of Plant Breeding and Genetics at the Joint FAO/IAEA Centre of Nuclear Applications in Food and Agriculture and is based in Vienna, Austria. Prior to this, she was global Director for two CGIAR Research Programs, Dryland Cereals and Grain Legumes, and successfully led the design and merger of the two into a multimillion-dollar mega-programme involving eight international (CGIAR) centres. Before this she coordinated the maize transgenic pipeline for agronomic traits from discovery research to early product development at DuPont Pioneer, now Corteva, at its headquarters in Iowa, USA. In this role, she provided leadership for discovery research in Australia, China, India, Japan and at Wilmington, Delaware, and early product testing in the Americas. This included candidate gene discovery, genetic associations, high-throughput vector construction/plant transformation and high-throughput phenotyping. During her career at DuPont Pioneer, Shoba also managed her own laboratory on stress physiology and digestibility and provided leadership for the establishment of DuPont's high-throughput phenotyping platform. Shoba is inventor in more than 100 patent applications, has authored several peer-reviewed publications, and edited books and special issues of journals. She did her PhD and post-doc at the University of Guelph, Canada, and MBA degree at the University of Iowa, USA.
Patrick J. Rich isa sorghum geneticist specializing in Striga resistance. He works at the University of Purdue in the laboratory of the 2009 World Food Prize Laureate, Gebisa Ejeta. Rich and his colleagues have identified several genes in sorghum controlling forage quality, drought and Striga resistance. He has received grants from the Bill and Melinda Gates Foundation, the International Atomic Energy Agency of the United Nations and the Rockefeller Foundation supporting his work on resistance to the parasitic weed Striga. Rich has co-authored 32 peer-reviewed publications, including 7 book chapters. His works have been cited in over 1000 publications. He received his Ph.D. in Plant Physiology from Purdue University.

This open access book is a compilation of protocols developed through a Coordinated Research Project of the Joint FAO/IAEA Center of Nuclear Techniques in Food and Agriculture, specifically focused on mutation breeding for resistance to Striga. The book consists of three sections; (i) a general introduction on Striga biology and impact and mutagenesis in cereal crops; (ii) protocol chapters focusing on field, screenhouse and laboratory screening and diagnostic for resistance to Striga asiatica and S. hermonthica in sorghum, upland rice and maize, and; (iii) efficiency enhancing technologies such as rapid crop cycling, doubled haploid production and genomics for mutation discovery and marker development. These chapters were written by well recognized experts in Striga biology and physiology, and cereal breeders. The book is intended to serve as a unique reference and guide for plant breeders and geneticists engaged in breeding for resistance to Striga in cereals.
