TL;DR: Besides having rapid growth, high sugar accumulation, and biomass production potential, sweet sorghum has wider adaptability and would be a logical crop option in lieu of sugarcane in such situations as water availability and purchased inputs.
Abstract: Sweet sorghum Sorghum bicolor (L.) Moench is a special purpose sorghum with a sugar-rich stalk, almost like sugarcane. Besides having rapid growth, high sugar accumulation, and biomass production potential, sweet sorghum has wider adaptability (Reddy and Sanjana 2003). Given that water availability is poised to become a major constraint to agricultural production in coming years (Ryan and Spencer 2001), cultivation of sugarcane becomes difficult. Sweet sorghum would be a logical crop option in lieu of sugarcane in such situations. Sweet sorghum can be grown with less irrigation and rainfall and purchased inputs compared to sugarcane. The sugar content in the juice extracted from sweet sorghum varies from 1623% Brix. It has a great potential for jaggery, syrup and most importantly fuel alcohol production (Ratnavathi et al. 2004a). The stillage after extraction of juice from sweet sorghum can be used for co-generation of power.

TL;DR: In this paper, the contribution of sorghum and pearl millet for micronutrient deficiency in the semi-arid tropics in India is discussed. But, the authors focus on providing vitamin and mineral supplements to pregnant women and young children and on fortifying foods during processing.
Abstract: About 26% of the Indian population is deficient in calories and 28% in protein (Chand et al. 2003). The deficiency is most acute among the poor. The magnitude of micronutrient [iron (Fe) and zinc (Zn)] deficit is particularly alarming among children, women of reproductive age, and pregnant and lactating women (Sharma 2003). Current efforts to combat micronutrient malnutrition in the developing world focus on providing vitamin and mineral supplements to pregnant women and young children, and on fortifying foods during processing (Per Pinstrup-Andersen 2000). The introduction of crop varieties selected and/or bred for increased Fe and Zn will complement these efforts. Micronutrient-rich sorghum [Sorghum bicolor (L.) Moench] and pearl millet [Pennisetum glaucum (L.) R. Br.] cultivars are being bred by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) to address micronutrient deficiency in the semi-arid tropics with funding support from HarvestPlus. An understanding of the dietary contribution to nutrient intake in major sorghum and pearl millet production/consumption regions would help in quantifying the micronutrient deficiency for better targeting sorghum and pearl millet cultivars. This paper summarizes the contribution of sorghum and pearl millet toward intake of nutrients in major sorghum and pearl millet growing regions in India.

TL;DR: Eighty-four sorghum lines, produced from parental lines of popular hybrids, cultivars, yellow endosperm lines, germplasm lines, lines characterized by high protein digestibility, lines with high lysine contents and waxy lines, were evaluated in Patancheru, Andhra Pradesh, India, during the post-rainy season of 2003-04.
Abstract: Eighty-four sorghum lines, produced from parental lines of popular hybrids, cultivars, yellow endosperm lines, germplasm lines, lines characterized by high protein digestibility, lines with high lysine contents and waxy lines, were evaluated in Patancheru, Andhra Pradesh, India, during the post-rainy season of 2003-04. Significant genetic differences for Fe, Zn and phytate contents, and agronomic and grain traits were observed. The grain Fe content ranged from 20.1 (ICSR 93031) to 37.0 ppm (ICSB 472 and 296 B), whereas the Zn content varied from 13.4 (JJ 1041) to 31.0 ppm (IS 11990). Zn and Fe contents, which showed substantial heritability, were significantly and positively correlated. Stover and grain yields were weakly and negatively correlated with grain Fe content, but were strongly and negatively correlated with the grain Zn content. The number of days to 50% flowering and plant height were weakly correlated with grain Fe and Zn contents. Grain luster was positively correlated with grain Fe content, but was weakly correlated with grain Zn content. The grains of non-yellow endosperm lines had trace amounts of ?-carotene. In 11 yellow endosperm lines, the grain ?-carotene content ranged from 0.56 (IS 24724) to 1.132 ppm (IS 26886), with 6 lines (IS 7684, IS 7776, IS 24703, IS 24868, IS 24883 and IS 26886) having higher ?-carotene contents than the average of 0.85 ppm. The ?-carotene content was poorly correlated with grain Fe and Zn contents. The grain phytate content, characterized by a slight variation between phenotypic and genetic coefficients of variation and high heritability, was weakly correlated with grain Fe and Zn contents.

TL;DR: The genotype x environment interaction influences greatly the success of breeding strategy in a multipurpose crop like sweet sorghum, and the stable hybrid that performed well across seasons and over the years for grain yield and stalk sugar yield is 'ICSSH 28'.
Abstract: The genotype x environment interaction influences greatly the success of breeding strategy in a multipurpose crop like sweet sorghum [Sorghum bicolor (L.) Moench]. Eleven improved sweet sorghum hybrids were evaluated in both seasons for three years and genotype main effects and genotype x environment interaction (GGE) biplot analysis revealed that the hybrids that performed well in rainy season are: 'ICSSH 24' and 'ICSSH 39' and post rainy season are: 'ICSSH 57' and 'ICSSH 28'. The stable hybrid, based on additive main effects and multiplicative interaction (AMMI) and GGE biplot analysis that performed well across seasons and over the years for grain yield and stalk sugar yield is: 'ICSSH 28'.

TL;DR: In this paper, the authors review aspects of soil science, plant physiology and genetics underpinning crop bio-fortification strategies, as well as agronomic and genetic approaches currently taken to biofortify food crops with the mineral elements most commonly lacking in human diets: iron (Fe), zinc (Zn), copper (Cu), calcium (Ca), magnesium (Mg), iodine (I) and selenium (Se).
Abstract: Summary The diets of over two-thirds of the world's population lack one or more essential mineral elements. This can be remedied through dietary diversification, mineral supplementation, food fortification, or increasing the concentrations and/or bioavailability of mineral elements in produce (biofortification). This article reviews aspects of soil science, plant physiology and genetics underpinning crop biofortification strategies, as well as agronomic and genetic approaches currently taken to biofortify food crops with the mineral elements most commonly lacking in human diets: iron (Fe), zinc (Zn), copper (Cu), calcium (Ca), magnesium (Mg), iodine (I) and selenium (Se). Two complementary approaches have been successfully adopted to increase the concentrations of bioavailable mineral elements in food crops. First, agronomic approaches optimizing the application of mineral fertilizers and/or improving the solubilization and mobilization of mineral elements in the soil have been implemented. Secondly, crops have been developed with: increased abilities to acquire mineral elements and accumulate them in edible tissues; increased concentrations of ‘promoter’ substances, such as ascorbate, β-carotene and cysteine-rich polypeptides which stimulate the absorption of essential mineral elements by the gut; and reduced concentrations of ‘antinutrients’, such as oxalate, polyphenolics or phytate, which interfere with their absorption. These approaches are addressing mineral malnutrition in humans globally.

TL;DR: Sorghum is a highly productive, drought-tolerant species with a history of improvement and production of lignocellulose, sugar and starch as discussed by the authors.
Abstract: The increasing cost of energy and finite oil and gas reserves has created a need to develop alternative fuels from renewable sources Currently, the development of a renewable transportation fuel is ethanol based Ethanol production is now sugar/starch based, but use of these carbohydrates is limited; they are also required as a food and feed source The need to generate a large and sustainable supply of biomass to make biofuels generation from lignocellulose profitable will require the development of crops grown specifically for bioenergy production There will be several different species used as dedicated bioenergy crops, and for several reasons; it is expected that sorghum (Sorghum bicolor L Moench) will be one of these species Sorghum is a highly productive, drought-tolerant species with a history of improvement and production of lignocellulose, sugar and starch Given this history and the existing genetic improvement infrastructure available for the species, it is logical to expect that sorghum hybrids for dedicated bioenergy production can be developed in the near-term future and will be grown and used for bioenergy production © 2007 Society of Chemical Industry and John Wiley & Sons, Ltd
