Rapid advances in genomics are providing the tools to determine genetic basis of quality (both nutritional and functional) cereals. This promises allow increased rates gain breeding by reducing need for extensive end-product testing new varieties. Many traits result relatively recent human selection thus likely be controlled only a few major genes. makes identification these genes use an attrac...

Cereal Chern. 75(1):100-104 Correlations among grain sorghum quality factors (proximate composition, physical properties, and water absorption properties) were evaluated. Samples of 46 commercial hybrids (24 and 22 from crop years 1993 and 1994) were analyzed for starch, protein, crude free fat, test weight, absolute density, 1,000 kernel weight, percent kernel abraded, water absorption index, ...

Sceds from over 9,000 lines in the world sorghum [Sorghinn bicolor (L.) Moeochj collection were classified for endosperm phenotype to identify floury endospermO lines and evaluate each for potential increases in lysine concentration. Sixty-two floury endosperin lines were selected and analyzed for protein and lysine composition. Two floury lines of Ethiopian origin, IS 11167 and IS 11758, were ...

Rice (Oryza spp.) is one of the most important food crops in the world, being planted on almost 11% of the Earth’s cultivated land area over a wide number of ecosystems (Khush, 2005; Maclean et al., 2002). Two species, Oryza sativa and O. glaberrima, are cultivated while other species are wild. Human selection and environmental factors have contributed to the genetic diversity in rice, particul...

Renewable fuel production, particularly grain-based ethanol, is expanding rapidly in the USA. Although subsidized grain-based ethanol may provide a competitively priced transportation fuel, concerns exist about potential environmental impacts. This contribution focuses on potential water quality implications of expanded grain-based ethanol production and potential impacts of perennial-grass-bas...
