This book was released on 2003 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because maize is a major feed crop in many parts of the world, it is important to optimize its nutritional value. However, maize protein is nutritionally limited by deficiencies in Lysine, Methionine, and Tryptophan. If the levels of the limiting amino acids could be improved through conventional breeding methods, it would reduce the cost of feed in meat production. The first part of this study consists of completing the first cycle of recurrent selection to test the potential of selection for Methionine and Tryptophan levels and to test the nutritional quality of the improved populations. After one cycle of recurrent selection, two maize populations, BS11 and BS31, were evaluated for their Methionine and Tryptophan levels. The progenies of the half-sib families categorized with high levels of Methionine in the starting populations had significantly higher Methionine levels than the progenies of those with low levels of Methionine. The response to selection for Tryptophan levels was negligible. The nutritional quality of the improved BS11 populations for Methionine was tested with a rat feeding trial. While the rats fed on the Low Methionine diet consumed significantly more feed than the rats fed on the High Methionine diet, there was no difference in either weight gain or feed efficiency. The second part of this study presents the variability for Methionine and Tryptophan levels in commercial maize germplasm and the genetic effects associated with those traits. Seventy-six inbred lines representing nine different genetic groups were evaluated. There was substantial variability within and among the genetic groups. Two diallel mating schemes were completed with parents selected for low or high Methionine or Tryptophan levels. The analysis of the diallel crosses revealed the following genetic effects: general combining ability, specific combining ability, and reciprocal effects. For the Methionine diallel, there were strong effects for general combining ability and specific combining ability. The reciprocal effects were expressed in the maternal direction. Given the success of recurrent selection, the variability for Methionine and Tryptophan levels, and the genetic effects associated with those traits, we conclude that the limiting amino acids of maize can be improved through conventional breeding methods.

This book was released on 2005 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been recognized that the genetic constitution of the maize kernel may have an impact on its chemical composition. Maize has been shown to be limiting in several of the essential amino acids required by monogastric animals, specifically lysine and methionine. Plant breeders are attempting to screen maize populations for lines containing higher essential amino acid levels and incorporate those traits into elite lines. However, in order for this to happen, the plant breeders need to have a reliable screening procedure. One such approach is to utilize an auxotrophic microbial assay to assess the specific amino acid concentration. In this study, a statistical review of the assay procedure was conducted along with a simulation program to help project the most practical, repeatable assay protocol. Subsets of fourteen maize samples were each ground to a fine powder before they were allocated in a RCB design on a 96-well microplate. A plate was comprised of three blocks each containing the same ground subset. Each grind was replicated across three plates for a total of nine plates. The individual plates were then measured three times. The conclusions of this study were that this assay is highly repeatable and consistent. The microbial assay was reviewed and found to be reliable for amino acid measurement. The repeatability of this assay was extremely high, with most of the repeatability values being above 90%. The assay was sensitive enough to detect genotypic differences between the entries. Only one replication of each field sample was necessary. In a simulation program, three plates is the practical number to replicate entries over in this assay. The block, grind, and plate by grind interaction effects were all determined to not be a significant source of variation in this assay. Any plant breeder can take comfort in this assay that the entries submitted would be consistently analyzed.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Grain quality traits of maize such as protein, oil, starch, and kernel size and density are essential for various end-uses; feed for animals, food for humans, and raw materials for industry. Kernel pigments like anthocyanins and carotenoids have numerous nutritional functions in animals and human beings. Increasing the levels of these compositional traits and pigments in kernels should increase the nutritional quality of maize.

Available in PDF, EPUB and Kindle. Book excerpt: The Maize Handbook represents the collective efforts of the maize research community to enumerate the key steps of standard procedures and to disseminate these protocols for the common good. Although the material in this volume is drawn from experience with maize, many of the procedures, protocols, and descriptions are applicable to other higher plants, particularly to other grasses. The power and resolution of experiments with maize depend on the wide range of specialized genetic techniques and marked stocks; these materials are available today as the culmination of nearly 100 years of genetic research. A major goal of this volume is to introduce this genetical legacy and to highlight current stock construction programs that will soon benefit our work, e. g. high-density RFLP maps, deletion stocks, etc. Both stock construction and maintenance are relatively straightforward in maize as a result of the ease of crossing and the longevity of stored seeds. Crossing is facilitated by the separate staminate (tassel) and pistillate (ear) flowers, a feature almost unique to maize. On the other hand, many of the genetic methodologies utilized with maize, including the precision of record keeping, can be adapted to other plants. Facile communication and a spirit of co-operation have characterized the maize genetics community since its earliest days. Starting in the 1930s, institutions such as annual Maize Genetics Cooperation Newsletter, the Maize Genetics Stock Center, and the annual maize genetics meeting provide continuity to the field.

Available in PDF, EPUB and Kindle. Book excerpt: The chapters presented in this book ‘Biofortification of Food Crops’ depict how agricultural technological interventions have true role in alleviating malnutrition. This book highlights the role of multidisciplinary approaches to cope up with the challenges of micronutrient malnutrition or hidden hunger which is an alarming public health issue in most parts of the world including India. In this endeavour, different biofortification approaches such as agronomic (or ferti-fortification), breeding, biotechnological, physiological, microbial etc. has fulfilled their different mandates of nutrient enrichment of food crops including cereals and pulses. The contents of the book proves that biofortified plants have adequate potential to nourish nutrient depleted soils, help increase crop productivity and provide nutritional benefits to plants, humans and livestock. The content and quality of information presented in this book will definitely provide multiple novel ideas of advance techniques and will stimulate innovative thoughts and directions amongst researchers and policy makers in the field of biofortification. In addition, the contributions presented in the book will be a good source of background knowledge and technical know-how to educate the readers about biofortification. The authors hope that the book entitled “Biofortification of Food Crops” would provide a suitable platform in our collective efforts for an appropriate dialogue among the scientists, researchers, entrepreneurs, policy makers and farmers in reducing the budding issues of malnutrition through novel approaches and means.
