Kelly O'Brien and Martin L. Price D:/cd3wddvd/NoExe/…/meister13.htm 4/242 19/10/2011 meister13.htm Characteristics Amaranth is a plant with an upright growth habit, cultivated for both its seeds which are used as a grain and its leaves which are used as a vegetble. Both the leaves and seeds contain protein of an unusually high quality. The grain is milled for flour or popped like popcorn. The leaves of both the grain and vegetable types may be eaten raw or cooked. The amaranths that are grown principally for vegetable use have better tasting leaves then the grain types. Amaranth has been cultivated for more than 8,000 years, dating back at least to the Mayan civilization of South and Central America. It was a staple of the Aztecs and was incorporated into their religious ceremonies. In 1516 the conquistadores prohibited the growing of amaranth. In that area today only a limited amount of grain is grown, most of which is popped and mixed with honey to make "alegria" candy. However, much of the genetic base has been maintained because amaranth has continued growing in the area as a weed. Amaranth is considered native to South and Central America, but over 400 varieties are found throughout the world in both temperate and tropical climates. Vegetable amaranth has been used in China for 400 years, and is commonly found in the Caribbean and Africa. Amaranths are moderately branched from a main stem. Grain types form large loose panicles at the tips of the stems. Vegetable types form flowers and seeds along the stems. They are indeterminate in growth habit, but may set seed at a smaller size during short days. Grain amaranth grown in winter at ECHO (southern Florida) began flowering at less than half of the height of amaranth growing in May. Grain types may grow 1 to 2 meters tall and produce yields comparable to rice or maize. Amaranth has the "C-4" photosynthetic pathway (along with such plants as corn and sorghum), which enables it to be uniquely efficient in utilizing sunlight and nutrients at high temperatures. It is more drought-resistant than corn. Nutritional value D:/cd3wddvd/NoExe/…/meister13.htm 5/242 19/10/2011 meister13.htm As can be seen in Table I, amaranth is quite nutritious. Amounts of vitamin C, iron, carotene, calcium, folic acid and protein are especially high. There are reports that the incidence of blindness in children due to poor nutrition has been reduced with the use of 50 to 100 g of amaranth leaves per day. On a dry weight basis, the content of protein in leaves is approximately 30%. The presence of rather high amounts of oxalic acid and nitrates places some limitation on the quantity of amaranth leaves that can be consumed daily. The amount of oxalic acid is roughly the same as that found in spinach and chard. Excessive amounts (over 100 g per day?) may result in a level of oxalic acid that begins to reduce the availability of calcium in humans. This is especially a concern if calcium intake levels are low to begin with. Nitrate in vegetable portions of amaranth is a concern because it is hypothesized that nitrates may be chemically changed in our digestive tracts into poisonous nitrosamines. Evidence for this is lacking at the present time. Nevertheless, over 100 g per day may be an unsafe amount to eat, according to scientists. The levels of both oxalic acid and nitrates are reduced by boiling the leaves like a spinach, then discarding the water. Amaranth grain has more protein than corn, for example, and the protein is of an unusually high quality. The protein is high in the amino acid lysine, which is the limiting amino acid in cereals like maize, wheat and rice. The protein is also relatively rich in the sulfur- containing amino acids, which are normally limiting in the pulse crops (e.g. beans). The "protein complement" of amaranth grain is very near to the levels recommended by FAO/WHO. It has a protein score of 67 to 87. Protein scores are determined by taking the ratio of the essential amino acids to the level for those amino acids recommended by FAO/WHO, and multiplying by 100. By comparison, wheat (14% protein) scores 47, soybeans (37%) score 68-89, rice (7%) scores 69, maize (9%) scores 35. Although amaranth is theoretically close to the ideal, combining it with another grain increases the quality to very close to the FAO/WHO standards. Weight gain studies with rats point out, however, that the actual nutritional value is considerably less than would be expected from the above considerations. This is apparently due to certain anti-nutritional factors in raw amaranth. Performance is improved somewhat by cooking. For example, Dr. Peter Cheeke at the University of Oregon compared the rate of weight gain by 120 gram rats fed a corn-soybean diet to rats fed a diet D:/cd3wddvd/NoExe/…/meister13.htm 6/242 19/10/2011 meister13.htm of corn and seed from A. hypochondriacus, either raw or cooked. The average daily gain for rats on the corn-soybean diet during the first 20 days was 3.9 grams. Rats fed the corn-amaranth diet gained only 0.3 grams per day. The average daily gain for rats fed corn and cooked amaranth was 1.6 grams. Raw amaranth seed is extremely unpalatable to rats (i.e.

ABSTRACT Cowpea (Vigna unguiculata [L.] Walp.) was originally domesticated in sub-Saharan Africa but is now cultivated on every continent except Antarctica. Utilizing archaeological, textual, and genetic resources, the spread of cultivated cowpea has been reconstructed. Cowpea was domesticated in Africa, likely in both West and East Africa, before 2500 BCE and by 400 BCE was long established in all the modern major production regions of the Old World, including sub-Saharan Africa, the Mediterranean Basin, India, and Southeast Asia.

  • Phytogeographic Basis Plant Breeding
    PHYTOGEOGRAPHIC BASIS of PLANT BREEDING 1. Local Varieties and Their Significance :— The -varieties of cultivated plants grown in the different regions of the Soviet Union until recently were varieties introduced from various localities and countries, and were inseparable from human migration and colonization. The list of cultivated plants reflects the history of our country in its recent past, it shows the effects of individual peasant farming. In the separate groups and varieties of plants one can trace the routes by which they were brought from Western Europe, the United States, Asia Minor, Mongolia, and Iran. In the pre-revolutionary period, the introduction of new varieties in our country was haphazard. Beginning with the eighteenth century, individual amateur growers and societies unsystemati- cally introduced new varieties from abroad. Sometimes these new varieties were quite valuable but because of the vastness of our country and the com- plete absence of any state-planned system of plant introduction, the imported varieties usually restricted themselves to very limited areas and disappeared. It may be considered that pedigree seed production, in the real meaning of the term, did not exist in our country before the October Revolution. We have just begun a planned distribution of varieties in accordance with the needs of our large-scale socialized and mechanized agricultural economy. Yet, there is no doubt that the varietal materials which were introduced in our country and cultivated for decades and centuries were subjected to natural selection, and also to deliberate or casual artificial selection, and that some local varieties evolved that were ecologically adapted. The proximity of the Soviet Union to the basic centers of origin of numer- ous cultivated plants facilitated the selection of exceptionally valuable forms.

The main important characteristics of this crop include the good protein quality with a high nutritional value, the nitrogen-fixing ability, and be more drought- and heat-tolerant than most of its legume relatives. In a research perspective, the studies with cowpea are relatively scarce, despite its relevance to agriculture in the developing world and its resilience to stress. This review provides an overview on different aspects of cowpea, with special emphasis on the molecular 1 markers for assessing genetic diversity, as well as on the biochemical and transcriptomic data to evaluate cowpea drought stress tolerance.

  • Genetic Diversity of Legume Species and Their Utilization in Vietnam
    54 JIRCAS International Symposium Series 2: 54-66 Session 1-5 (3) Genetic Diversity of Legume Species and Their Utilization in Vietnam TRAN, Van Lai' and MAI, Quang Vinh" Abstract Due to the wide range of latitude and complicated topography. Vietnam is very rich in plant genetic resources, of which legumes are widespread and economically important. After a series of studies, Vietnamese breeders and researchers have evaluated a large number of legume accessions. Based on the resulted, it became possible to proceed to the selection, in­ duce mutations and breed several legume varieties and lines that can meet various require­ ments of production and environmental protection. Despite the great success in their utilization, since many legume species have not been properly studied, they remain non-or under-utilized. To preserve and use the legume genetic resources in Vietnam, more concerted efforts on the part of the researchers, as well as close cooperation and collaboration with various organizations in the world are required. Natural conditions and economic importance of legume development in Vietnam Vietnam is a small country. With 330,000 km' of territory curving as an S letter stretching over 1,600 km from 8° 23' to 23' 22' North there are diverse climatic conditions : tropical, subtropical as well as tem­ perate in the high mountains of the northern, central and southern parts of the country. In general Viet­ nam is typically a tropical and monsoon country, where winter is distinctly a dry season. In the northern plains the cold winter lasts from November to April, the average temperature being l6°C.
