Rodomiro Ortiz is Professor of Genetics and Plant Breeding at the Swedish University of Agricultural Sciences (SLU) in Alnarp, Sweden. He worked as geneticist at Universidad Nacional Agraria La Molina (UNALM), Centro Internacional de la Papa (CIP, Lima, Perú), Rutgers University (Chatsworth, New Jersey, USA) and International Institute of Tropical Agriculture (IITA, Ibadan, Nigeria), held a Nordic professorship in plant genetic resources at the Danish Royal Veterinary and Agricultural University (merged now with the University of Copenhagen, Denmark), served as Director at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT, Patancheru, Telangana, India), IITA, and the Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT, El Batán, México), and independent free-lance consultant for international, regional and national organizations engaged in agricultural research-for-development. CGIAR awarded IITA in 1994 the prestigious King Baudouin Award for the multidisciplinary research of the team working in plantain and banana improvement, in which Ortiz was both a hands-on researcher and program leader. His professional expertise includes genetics, genetic resources, germplasm enhancement, plant breeding, agro-biotechnology, biosafety, intellectual property rights, and developing agro-ecosystem and livelihood system approaches aiming sustainable intensification of agriculture in the developing world.

ing to Google Scholar at end 2014.This book provides analysis of plant breeding and its role for producing high-yielding cultivars that increase farming profitability and sustainability. This work analyzes the past and present of plant breeding, while providing research that investigates the future of crop improvement. Plant breeding today, as it was before, depends on crop biodiversity and its sustainable use, which can be further facilitated by advances in omics and bioinformatics. It starts with assessing plant genetic resources (wild species, landraces, obsolete cultivars, genetic stocks) variation aiming to enhance the cultigen pool. Research on genetics–aided by current omic tools– should lead to designing a knowledge-based plant breeding, which could bring further genetic gains in the breeding pools. Plant breeding, however, will increasingly require pursuing a holistic interdisciplinary approach based on integrated system-oriented thinking.
