This book was released on 2004 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. CIMMYTs̉ success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers have provided benefits to Australia averaging A$30 million per year since 1973. If these benefits are to continue in the future, Australia must continue its close relationship with CIMMYT"--Abstract.

Download or read book Beyond Semi-Dwarf Wheat Yield Increases written by John P. Brennan and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. While the initial impact came through the introduction of higher-yielding semi-dwarf wheat crops, those impacts have continued in the post-semi-dwarf period. CIMMYT's success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers from both the semi-dwarfs and the post-semi-dwarf phases have provided benefits to Australia averaging A$30 million per year.

Available in PDF, EPUB and Kindle. Book excerpt: Scientific breeding in the twentieth century greatly accelerated wheat`s evolution, producing high-yielding varieties that helped avoid famine in many developing countries. Emerging scientific tools hold promise for identifying and tapping new, useful genetic diversity within wheat`s primary and secondary gene pools and, through genetic engineering, beyond.The book describes generally how policies affect wheat genetic diversity; it looks at historical changes in wheat genetic diversity, as policy and priorities have evolved; it identifies factors that explain changes and differences in spatial diversity; and finally, it analyzes the productivity impacts of changes in diversity. Chapters define various types of crop genetic diversity and ways to measure them, framing the definitions and metrics in the contexts for which they are most relevant.

Download or read book The Genetic and Economic Impact of the CIMMYT Wheat Breeding Program written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies show that there has been a deceleration in world wheat yield growth, specifically in irrigated areas, which has led some to believe that the potential for genetic gains is slowing. Some reports claim that the Centro Internacional de Mejoramiento de Maiz y Trigo (CIMMYT) breeding program "reached a plateau" in the 1980s. Such a breeding plateau would have global ramifications, since it is often poor consumers who benefit the most from yield enhancement of staple crops including wheat. CIMMYT estimates that by 2020, the developing world will need 40% more wheat than it consumes today. Because of the lack of involvement by private breeders in most low-income countries, CIMMYT, whose germplasm is used extensively in the developing world, will need to ensure that modern varieties that they release are increasing in yield to meet the rising wheat demand in the developing world. CIMMYT, a non-profit organization, distributes improved germplasm to national agricultural research systems (NARS) for worldwide utilization. CIMMYT has consistently invested a large amount of public expenditures in wheat breeding research each year for several decades. Estimates of the impact of the wheat breeding program on increasing wheat yields provides information to scientists, administrators, and policy makers regarding the efficacy and return to these investments. Quantitative estimates of yield improvements due to the wheat breeding program provide important information for future funding decisions. Wheat lines released by CIMMYT during 1962-2002 were analyzed to estimate genetic yield increases associated with the CIMMYT breeding program using test plot data from the Yaqui Valley in Mexico from 1990-2002. Using several econometric techniques including a Just-Pope production function to account for multiplicative heteroscedasticity across the different varieties, results indicate that through the release of modern varieties CIMMYT has contributed 53.77 kg/ha to yield annually in Mexico's Yaqui Valley during 1962-2002. Estimates of the gains attributed to CIMMYT's breeding program on a global scale equal 481.47 million (2002) USD annually from 1990-2002. CIMMYT's average total wheat breeding cost in from 1990-2002 was roughly 13.95 million USD making the average cost-benefit ratio approximately 1:34.

Book excerpt: Discussing the latest processes involved in researching yield generation, Wheat: Ecology and Physiology of Yield Determination will help you design various types of crop production systems for maximum yield. Featuring information on developing high-yielding, low-input, and quality-oriented systems, this book offers you both physiological and ecological approaches that will help you understand the crop as well as increase its production. Discussing aspects of wheat growth for specific regions around the world, Wheat provides you with information that will improve the size and quality of your crops, including: how temperature, vernalization, and the photoperiod affect the development of wheat using the correct amount of nitrogen fertilizers for wheat crops an explanation of the reproduction and nitrogen cycles of wheat how elements and conditions such as lipids, proteins, nitrogen, and climate enhance grain quality estimating and determining optimal sowing dates examining factors that may affect wheat yield-density relationships, such as planting arrangement and date of sowing preventing seed decay and examining effects of mildews and leaf blights examining historical trends of the crop to see what further research needs to be done You'll also receive information on the genetic gains in wheat research that are improving the physiological traits and numerical components of this essential grain. Within Wheat, you'll find data and methods from international experts in the field that will improve the yield and growth of the world's most important crop.
