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.

Available in PDF, EPUB and Kindle. Book excerpt: Genomic Applications for Crop Breeding: Abiotic Stress, Quality and Yield Improvement is the second of two volumes looking at the latest advances in genomic applications to crop breeding. This volume focuses on advances improving crop resistance to abiotic stresses such as extreme heat, drought, flooding as well as advances made in quality and yield improvement. Chapters examine advances in such key crops as rice, maize, and sugarcane, among others. Genomic Applications for Crop Breeding: Abiotic Stress, Quality and Yield Improvement complements the earlier volume on biotic stressors and will be an essential purchase for those interested in crop science and food production.
Download or read book Biofortification of Food Crops written by Ummed Singh and published by Springer. This book was released on 2016-01-22 with total page 489 pages. 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.

This book was released on 2013-12-03 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maize is a globally important crop mainly utilized as feed, food and raw material for diverse industrial applications. Among cereals, it occupies third place after rice and wheat and is a staple food for a large segment of population worldwide particularly in the Asian as well as African countries. This monogram discusses various aspects of nutritional quality of maize such as quality protein maize which has been considered as most significant discovery in enhancing nutritional quality of cereals in terms of increasing the concentration of essential amino acids. The biochemistry of starch which is an important industrial product of maize has been discussed in detail. Further, the role of maize oil which is highly regarded for human consumption as it reduces the blood cholesterol concentration has also been elaborated. Naturally, maize is a rich source of carotenoids such as beta-carotene, zeaxanthin, lutein, cryptoxanthin which have highly diverse health benefits ranging from maintaining normal vision to lowering of oxidative stress. The need for biofortification of maize for provitamin A carotenoids and their role in alleviating vision impairments have also been discussed. The effect of various biotic and abiotic stresses particularly carbon dioxide and temperature on quality has been discussed thoroughly. Many value-added products as well as fermented foods that have been produced from maize which is consumed in different forms worldwide are also discussed. The aspects related to the maize application as fodder and as a source of malting have also been covered concisely. Overall, the book provides complete information about various quality aspects of maize. The various stakeholders such as maize researchers, extension specialists, students, teachers as well as farmers will be immensely benefitted from this monogram.
