Available in PDF, EPUB and Kindle. Book excerpt: India is the second largest producer of vegetable next to China. Cowpea is one of the most important leguminous vegetable crop. The area is increasing day by day under Cowpea crop, however, no suitable variety/ genotype is available to fulfill the present demand in case of the maximum yield with better quality. If we consider, the world scenario of cowpea production, India is far behind in productivity. So the increase in the production of cowpea is being possible by using best variety in most suitable time. Considering the productivity trends there is a need to increase the cowpea production by introducing new genotypes by sowing at different times. This book contains valuable knowledge in crop science, plant genetics, crop physiology, horticulture, and other relevant disciplines. This book will be of significant interest to advanced undergraduate and post-graduate students of Horticulture, Plant physiology, Crop science, Plant genetics and rural development as well as NGO workers and farmers.

Walp) Genotypes for Adaptation to Low Soil-phosphorus Conditions and to Rock Phosphate Application written by Sabiou Mahamane and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cowpea (Vigna ungiculata L. Walp) is a major food and fodder legume in poor countries, particularly Sub-Saharan Africa countries. It is generally produced in sandy, acid soils, deficient in phosphorus (P) which severely limits its production. Because processed phosphate fertilizers are expensive and poorly available to farmers, rock phosphate is viewed as a cheap alternative phosphate source. The present study evaluated 696 U.S Core Collection and IITA cowpea accessions for adaptation to low soil P environments and for response to rock phosphate application. Subsequently, organic acid exudation by selected cowpea genotypes as a mechanism for P acquisition from Fe-oxide and Ca bound P was investigated. A low P soil from Nacogdoches pine forest was used to grow plants. There were two P treatments: 0 and 300 mg P/kg of soil as Tahoua (Niger) rock phosphate. At harvest, plant height, shoot and root dry weights were determined and total biomass and shoot-to-root ratios were computed. Shoot P contents of 100 selected accessions were measured. Sixteen accessions reflecting the wide array of responses observed were selected for the organic acid study. Plants were grown in a growth chamber hydroponically with no P and +P nutrient solutions for 3 weeks. Organic acids were collected in a CaCl2-KCl solution. The nature and quantity of the collected organic acids was determined. Cowpea accessions were significantly different in their ability to adapt to Pdeficiency stress and to acquire P from rock phosphate. The parameters most effective in separating the accessions were shoot mass and total biomass. This data will be potentially useful in the selection of cowpea germplasm for (1) adaptation to West African soils of low P fertility, and (2) ability to utilize P from poorly soluble rock phosphate. The predominant organic acid exuded by cowpea roots was a tricarboxylic acid not yet identified. There was surprisingly more exudation of this acid under +P than under -P conditions. Exudation was more highly correlated to roots than to shoots.

Available in PDF, EPUB and Kindle. Book excerpt: The projected increase in world population levels and the subsequent rise in food demand represents a huge challenge for agricultural production systems worldwide. This publication examines the opportunities and challenges raised by the use of plant genetic resources and highlights the contribution that data from multi-environment yield trials can provide for the definition of adaptation strategies and yield stability targets in plant breeding programmes. It contains a case study about a durum wheat crop programme in Algeria, and also includes a CD-ROM with data from IRRISTAT, a programme developed by the International Rice Research Institute (IRRI).

Available in PDF, EPUB and Kindle. Book excerpt: This report is the second in a series of three evaluating underexploited African plant resources that could help broaden and secure Africa's food supply. The volume describes the characteristics of 18 little-known indigenous African vegetables (including tubers and legumes) that have potential as food- and cash-crops but are typically overlooked by scientists and policymakers and in the world at large. The book assesses the potential of each vegetable to help overcome malnutrition, boost food security, foster rural development, and create sustainable landcare in Africa. Each species is described in a separate chapter, based on information gathered from and verified by a pool of experts throughout the world. Volume I describes African grains and Volume III African fruits.

Available in PDF, EPUB and Kindle. Book excerpt: Cowpea [Vigna unguiculata (L.) Walp.] (2n=2x=22) is a leguminous crop providing inexpensive protein for human consumption that can be grown worldwide. Salinity is one of the major threats to cowpea production, particularly in semi-arid regions of Africa. Salinity significantly affects seed germination and decreases pod yield in cowpea. However, little has been done to provide farmers salt-tolerant cowpea cultivars. Knowledge on the genetics of cowpea salt tolerance is very limited. This study aimed to:(1) evaluate cowpea salt tolerance at germination stage, (2) evaluate cowpea salt tolerance at seedling stage, (3) conduct an association study for cowpea salt tolerance at germination and seedling stages and to identify SNP markers associated with salt tolerance in cowpea. A total of 151 cowpea genotypes at germination stage and 203 cowpea genotypes at seedling stage were evaluated in this research. Association analysis was performed on 116 genotypes at germination stage and 155 genotypes at seedling stage. The results indicated that: (1) substantial variability in salt tolerance was found among the tested cowpea genotypes at both germination and seedling stages; (2) three SNPs, Scaffold87490_622, Scaffold87490_630, and C35017374_128 were highly associated with salt tolerance at germination stage; (3) seven SNPs Scaffold93827_270, Scaffold68489_600, Scaffold87490_633, Scaffold87490_640, Scaffold82042_3387, C35069468_1916, and Scaffold93942_1089 were found to be associated with salt tolerance at seedling stage, and (4) PI582422, 09-529, PI293584, and PI582570 were highly salt tolerant at germination stage, and PI293570, PI582812, PI582856, PI180014, PI257463, 09-175, 09-529, PI666260, I582402, and PI582340 were highly salt tolerant at seedling stage. This research will have practical applications in cowpea breeding and genetics. The salt tolerant lines could be used as parents for breeding programs and the SNP markers could be used as a tools in cowpea molecular breeding through marker-assisted selection.
