Posted by Jose Juan Caballero on , in CIMMYT Publications

Prasanna, B.M.;  Vijay Chaikam and George Mahuku

Abstract: This manual is primarily intended for maize breeders in the national agricultural research systems (NARS) and small and medium enterprise (SME) seed companies in the developing countries  who would like to better underst and utilizes the doubled haploid (DH) technology in breeding programs. It is a compilation and consolidation of knowledge accumulated through scientific contributions of several maize geneticists and breeders worldwide as well as protocols successfully developed (in collaboration with University of Hohenheim, Germany) and being used by the CIMMYT Global Maize Program in DH line development, especially in Mexico. An overview of the utility and applications of DH technology in maize breeding is presented first in the Manual, followed by Chapters on in vivo maternal haploid induction using haploid inducers, haploid kernel detection using anthocyanin markers, chromosome doubling of haploids, deriving DH seed from colchicine‐treated plants, DH in commercial maize breeding, integrating molecular markers in DH‐based breeding pipeline, and finally, access to tropicalized haploid inducers and DH service from CIMMYT.

Seeds of Sustainability: Lessons from the Birthplace of the Green Revolution in Agriculture

Edited by Pamela Matson

ISBN: 978-1-59726-525-6

Seeds of Sustainability is a groundbreaking analysis of agricultural development and transitions toward more sustainable management in one region. An invaluable resource for researchers, policymakers, and students alike, it examines new approaches to make agricultural landscapes healthier for both the environment and people.

The Yaqui Valley is the birthplace of the Green Revolution and one of the most intensive agricultural regions of the world, using irrigation, fertilizers, and other technologies to produce some of the highest yields of wheat anywhere. It also faces resource limitations, threats to human health, and rapidly changing economic conditions. In short, the Yaqui Valley represents the challenge of modern agriculture: how to maintain livelihoods and increase food production while protecting the environment.

Contenido

Prologo: Se considera prácticamente imposible compendiar con cierta profundidad la importancia del maíz en México a través de innumerables puntos de vista, entre los que destacan el alimentario, cultural, social, de  salud pública, económico, científico, ecológico, productivo, pecuario, industrial, nacional y mundial. Sin embargo, todos estos aspectos se encuentran profundamente involucrados en la siembra de los maíces criollos (locales o nativos) en más de 6 millones de hectáreas en todo el país y, que la diversidad genética involucrada para adaptarse en toda una gama de condiciones ambientales, constituyeun común denominador en los puntos de vista mencionados.

 Borlaug, Volume 3, Bread Winner 1960-1969

Author: Noel Vietmeyer

ISSB: 978-0-578-06920-3

Product Description

Volume 3 exposes the almost incredible saga of how the seeds Norman Borlaug created in Mexico [Volume 2] ended up saving millions of lives on the far side of the world.
As the book opens, Borlaug is so little appreciated his wheat-breeding program has been closed down. He’s resigned himself to becoming a banana breeder in Honduras.
As the book closes in 1969 India and Pakistan have survived a famine and, thanks to Borlaug’s Mexican wheats and his long, lonely struggle, food production is soaring.
All the behind-the-scenes drama is here to be relished for the first time. These pages expose dozens more adventures, surprises, and “Angels of Deliverance” as Norm rises from his career’s lowest point to its ultimate high point.

Borlaug, Volumen 2, Wheat Whisperer 1944-1959

Author: Noel Vietmeyer

ISBN: 978-0-578-03856-8

Product Description

Norman Borlaug is the mild-mannered maverick who lifted the world s food supply and saved a billion lives. He died the day before this book went to press. Having spent more than a decade assessing him and his contributions, the author sadly appended a few thoughts that included the following:More than a man of peace, he was a man of the people. His style and personality matched his frame lean, active, unassuming, unpretentious. People not only responded, they bonded.

Though otherwise a nice guy, he was a fierce, take-no-quarter, Hunger Fighter. His field was action science, not academic science. Among the wheat he was so intense people got hot just watching him work.

He was a master at managing mayhem and had an innate ability to transcend anxiety. Though often treated like a heretic in heaven, he never took offense, never abandoned his convictions, seldom lost composure. When it looked as if the Rockies had crumbled, he went on exploring the mysteries of the wheat world with his normal intensity . . .waiting for just the right gene to surface like a fish in a pool.

He was not a man of inspiring words, just inspiring wheats. But those spoke volumes.

He was never one to look in life’s rear-view mirror; being too busy driving hard into the future for anything so wasteful of time.

The only burden to never afflict him was the burden of extreme wealth. He worked his whole life without personal gain and was happy, nay eager, to let everyone else reap the rewards.

While others dreamed and dithered, he proved his worth through deeds. He chose to fight hunger not to write about it. And he chose to fight it full-frontal, full-scale, and in the places that needed food most. Moreover, he was an all-round Hunger Fighter a source of all the necessary ammunition.

His great gift was to share his exuberance and conviction. His spirits were usually as high as the Sonoran Desert thermometer at harvest time. With his associates many of them disadvantaged youths he developed an extraordinary esprit de corps. They trusted one another, and that provided a key to their success.

He taught us what to do when the diktats of dogma block humanitarian needs. “Fight,” he d often say; “Fight, fight, fight!”

He admired horizon-filling miles of his own wheats but never gloated. He took yields to galactic heights but saw it only as his job and always felt unfulfilled.

Borlaug; Volume 1, Right off the Farm. 1914 – 1944

Author: Vietmeyer Noel

ISBN: 978-0-578-04125-4

Product Description

Borlaug is a biographical series detailing how the greatest of all human disasters came ever so close to occurring. For good reason, it has been called The World’s First Cereal Thriller. Without the myriad twists and turns in a single scientist’s career a sizable proportion of the human race would by now have starved.

You see, in the middle of the 20th Century the world was fast running out of food. Earth’s 3 billion people were then producing babies at a rate to double the population by century’s end; yet global food production was stuck in first gear; the good farmland was in full use and its per-acre productivity was barely budging. The catastrophe arising from too little food to feed the human race seemed inevitable; no one in authority had any practical answer. Human numbers were about to plunge, unraveling whole societies and entangling every nation in all-consuming chaos.

These volumes highlight the amazing chain of circumstance that produced the Nobel Peace Prize winner Norman Borlaug as well as his super-producing wheats. This loner’s starvation-busting seeds arrived seemingly heaven sent to save hundreds of millions from the slowest and most agonizing of all deaths. India’s wheat production, to cite just one example, soared in less than two years from 12 to 20 million tons a rise so unexpected that, to protect the grain from the monsoon rain, the schools had to be closed and co-opted as granaries.

Volume 1 opens this series, laying the foundation for the human drama behind all that hardly known history. It divulges the searing experiences that developed Norman Borlaug’s dedication, drive and motivation to help the hungry. A powerful blend of biography, history, science, adventure, and what might be called the American spirit, it relates in lively prose how young Borlaug often went hungry himself and how high-yielding seeds (corn, in this case) lifted his own family from poverty in rural Iowa. It also highlights Angels of Deliverance most of them strangers who selflessly interceded when his path to progress seemed forever blocked. In addition, its pages are sprinkled with surprises, coincidences, “can-do” characters and personal dramas such as Borlaug s life during the months the president forced all Americans to diet because the wheat crop had failed. Beyond all that, young Borlaug lives through the 1918 flu, the Great Depression, joblessness, a forest fire and very much more.

New CIMMYT Publications: Mass Rearing of Stem Borers, Maize Weevil, and Larger Grain Borer Insect Pests of Maize

 INTRODUCTION 
Maize ( Zea mays L.) is important for agriculture and livelihoods in eastern and southern Africa as it is the major staple food. However, maize yield in Africa is very low, 1.5 t/ha, against a global average of 4.9 t/ha. Constraints to maize production include both abiotic and biotic factors. Among the biotic constraints in maize production, are insect pests in the field and in storage. The most economically important insect pests of maize in Africa include stem borer in the field, and both the maize weevil (MW) and larger grain borer (LGB) in storage (post-harvest pests). Maize plants are less able to tolerate stem borer attack than sorghum and pearl millet plants because they do not produce tillers, and the effect on grain yield is therefore greater. Colonization of the plant by borers, severity of infestation and damage strongly depend on the cropping system, soil fertility, and environmental conditions, which affect the nutritional status of the plant. Stem borer damage is aggravated by the poor nutritional status of the plant. Studies on several stem borers species in Africa showed that an increase in nitrogen is related to higher pest loads and tunnel damage. However, soil nutrient levels, such as nitrogen, also greatly influenced the plant’s tolerance to stem borer attack. This is due to an increase in plant vigor, which is reflected in lower yield losses (Setamu et al. 1995). Damage caused by stem borers can average 20 to 40%, which means between two to four bags of maize are lost out of every 10 that could be harvested (De Groote et al. 2003).
