- Impact of public and private sector maize breeding research in Asia, 1966-1997/98(CIMMYT, 2001) Gerpacio, R.V.This book presents results of a study of the impacts of international maize breeding research in seven developing countries of Asia (China, India, Indonesia, Nepal, the Philippines, Thailand, and Vietnam). It provides comprehensive, updated documentation of the status of Asia's national maize seed industries, including information on the roles of the public and private sectors in maize R&D, descriptions of the germplasm products developed by public and private breeding programs, data on the extent of farmers' adoption of modern maize varieties, and analysis of varietal adoption patterns and trends. Information on emerging trends in maize research and maize seed industries is also provided. An introductory chapter on the maize economy of Asia is followed by a chapter synthesizing results of the study for Asia as a whole. More detailed, country-level studies are presented in the remaining six chapters.
Publication - Towards reduced pesticide use for cereal crops in Asia(CIMMYT, 1997) Pingali, P.L.; Gerpacio, R.V.Several opportunities are available for dramatically reducing the use of agrochemicals in Asia cereal crop production. The first selection of this paper summarizes past trends and future prospects for pesticide use in Asia for three major cereal crops: rice, wheat, and maize. The second section identifies factors that have contributed to rising farm-level demand for pesticides and factors that could lead to a reduction in their demand. The third section highlights the advances that have been made in generating and disseminating cereal crops with resistance to insects and diseases. It focuses on conventional breeding strategies for host-plant resistance as well as the current and potential contributions of biotechnology. Pesticide productivity, yield variabiliy, and their relation to host-plant resistance are reviewed, along with evidence from trials and farmers' fields. The paper concludes with a discussion of the integrated management approaches that will be necesary for maximizing and sustaining the productivity gainsoffered by resistant varieties.
