Genetic and Agro-Morphological Diversity and Genotype by Environment Interaction of Yield and Nutritional Quality Traits in Pearl Millet Germplasm from Sudan


Book Description

Due to its adaptation to extremely harsh environments, pearl millet (Pennisetum glaucum (L) R. Br.) is one of the most important staple cereals cultivated in the arid and semi-arid tropics of Asia and Africa. In these regions pearl millet is mainly produced under low-input, rainfed conditions in traditional farming systems, where several constrains are affecting pearl millet production, such as inter-annual rainfall variability, pests, diseases, Striga and use of low yielding varieties. The majority of the human population in these regions is affected by nutritional deficiencies of essential minerals causing micronutrient malnutrition (so-called ‘hidden hunger’). Plant genetic resources provide basic materials for selection and improvement of crop productivity through the optimal design of breeding programs to meet food security needs of the world’s rapidly rising population. The advent of PCR-based molecular markers such as simple sequence repeats (SSRs) has created an opportunity for fine-scale genetic characterization of germplasm collections. Understanding the structure of diversity and the identification of distinct materials with complementary traits for recombination by crossing provides the foundation for effective and sustained pearl millet population breeding and synthetic and hybrid development, based on the concept of heterotic groups in this allogamous crop.




Harvesting Plant and Microbial Biodiversity for Sustainably Enhanced Food Security


Book Description

The World population will reach 9 billion by 2050, with the majority of this growth occurring in developing countries. On the other hand, one in nine of the World's population suffers from chronic hunger, the vast majority of which live in developing countries. We therefore need to find new and sustainable solutions to feed this increasing population and alleviate the predicted negative impact of global changes on crop production. This e-Book deals with new strategies to improve food security and livelihoods in rural communities, reduce vulnerability, increase resilience and mitigate lthe impact of climate change and land degradation on agriculture. This collection of 18 articles addresses the major abiotic factors limiting crop production worldwide, how to characterize and exploit the available plant biodiversity to increase production and sustainability in agrosystems, and the use of beneficial microbes to improve production and reduce the use of fertilizers and pesticides.




Genetic Diversity Analysis of Pearl Millet Hybrids Through Markers


Book Description

Pearl millet (Pennisetum glaucum (L.) R. Br.) is commonly known as pearl, cat tail, spiked or bulrush millet in English is world's sixth important and widely grown potential food cereal crop in agriculture in India and Africa. The pearl millet is an annual tillering diploid (2n=14), belongs to Division: magnoliophyta, Class: liliopsida, Order: poales, Family: Poacae, Sub family Paniceidae, Genus: pennisetum, Species: P. glaucum and is believed to be originated in Africa, where the greatest diversity of morphological types exists. The center of diversity for the crop is in the Sahel zone of West Africa.In pearl millet a large number of crosses evaluated in hybrids each year. The characterization and identification of cultivars/hybrids is an urgent requirement. However, all types of marker are not suitable or feasible for the characterization and identification of hybrids. Morphological markers are less useful mainly due to lack of availability of an adequate number of ideal morphological markers in several hybrids.Molecular and biochemical markers are important tool for breeding selection, genotype identification and studying the organization and evolution of plant genomes.

The Museum of Bioprospecting, Intellectual Property, and the Public Domain


Book Description

‘The Museum of Bioprospecting, Intellectual Property, and the Public Domain’ addresses one of the most pressing policy issues of our day: intellectual property rights versus the public domain in facilitating access to genetic resources for biotechnology development. The issue is examined in the context of a proposal submitted by seven fictional scholars to an imaginary octogenarian, whose humor provides an original addition to the discussion.
