Eagle Lager: A Sorghum Success Story On Many Levels, Ian Mackintosh Dec 2010

Eagle Lager: A Sorghum Success Story On Many Levels, Ian Mackintosh

INTSORMIL Presentations

In 1999 in Uganda we were faced with a static but highly competitive market.

Needed to grow our market and to do this we needed to make beer cheaper

It was felt that a suitable local ingredient would reduce the cost of manufacture and stimulate local agriculture and the economy as well as provide opportunities for growth and profit for the company.

An extensive base line study of the Ugandan agricultural sector was undertaken to determine what was “out there.”

It was clear that there was enormous potential but little else.

Sorghum seemed the logical starting point because there was …

Economic Analysis Of Small Scale Sorghum Processing In Dar Es Salaam, Tanzania, Jeremia Makindara, Joseph J. Mpagalile, Wenceslaus Ballegu

INTSORMIL Presentations

Due to small scale food processing initiatives, several entrepreneurs dealing in small scale sorghum processing have emerged in Tanzania and especially in urban centers such as Dar es Salaam. The recent initiative that has contributed to this is the SUA-INTSORMIL Project that started in 2005. However, despite such initiatives being received by many entrepreneurs, very few economic studies have been conducted to assess the benefits obtained by sorghum processing entrepreneurs and the challenges they face are not well explained. This study therefore assessed costs and benefits obtained by small scale sorghum processing entrepreneurs in Dar es Salaam and the challenges …

INTSORMIL Presentations

Sorghum and pearl millet rank second and third, respectively, as important staple cereals after maize.

-There are new market developments in the beer industry requiring farmers to increase productivity and production

-These markets can significantly affect access to improved seed, and thus increase decisions on utilization

-Even though market developments indicate great potential for the two crops, their supply has remained erratic

-There was need therefore to identify the constraining factors to steady supply of sorghum & millet grain through conducting a seed value chain

Evaluation Of Novel Input Output Traits In Sorghum Through Biotechnology, Tejinder K. Mall Dec 2010

Evaluation Of Novel Input Output Traits In Sorghum Through Biotechnology, Tejinder K. Mall

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Sorghum [Sorghum bicolor (L.) Moench] is the fifth most important cereal crop world-wide as well as an important source of feed, fiber and biofuel. It is a C4 plant and is well adapted to environments subject to high temperature and water limitation. Despite these agronomic qualities, it suffers from limitations of sensitivity to low temperature and the grain has drawbacks in relation to functionality and digestibility. The objectives of this study are: 1. To promote seed germination at low temperature and to enhance the seedling cold tolerance. 2. To enhance the grain digestibility and functionality. In an attempt to …

INTSORMIL Scientific Publications

In the Central Plateau of Burkina Faso, grain sorghum [Sorghum bicolor (L.) Moench] is the major cereal crop used to produce the traditional beer called dolo. Grain sorghum grain samples collected in 2004 and 2005 from experiments combining five water management techniques and four fertilizer treatments in a randomized complete block design with a split plot arrangement of treatments were analyzed for the physicochemical properties of raw grain, and quality of malted grain. Water management techniques were allocated to main plots and fertilizer treatments to subplots. The objective was to determine the best combination of water management technique and …

Sorghum And Pearl Millet Improved Seed Value Chains In Zambia: Challenges And Opportunities For Smallholder Farmers, Priscilla Hamukwala, Gelson Tembo, Don Larson, Mark Erbaugh

INTSORMIL Scientific Publications

Sorghum and millet are a very important source of food and farm income for smallholder farmers, which can be enhanced especially if linked to new markets. These two crops have been widely viewed as minor traditional crops in the Zambian food systems. The two crops were displaced by maize in the 1900s with the opening of the copper mines. However, they remain important food crops for semi-arid areas of the country. In recent years, there have also been new market developments requiring farmers to increase productivity and production. Unfortunately significant productivity enhancements are impeded by low access to improved technologies …

Genetic Mapping Of Quantitative Trait Loci Associated With Bioenergy Traits, And The Assessment Of Genetic Variability In Sweet Sorghum (Sorghum Bicolor (L.). Moench), Aatshwaelwe Lekgari Lekgari Aug 2010

Genetic Mapping Of Quantitative Trait Loci Associated With Bioenergy Traits, And The Assessment Of Genetic Variability In Sweet Sorghum (Sorghum Bicolor (L.). Moench), Aatshwaelwe Lekgari Lekgari

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Sweet sorghum, a botanical variety of sorghum is a potential source of bioenergy because high sugar levels accumulate in its stalks. The objectives of this study were to explore the global diversity of sweet sorghum germplasm, and map the genomic regions that are associated with bioenergy traits. In assessing diversity, 142 sweet sorghum accessions were evaluated with three marker types (SSR, SRAP, and morphological markers) to determine the degree of relatedness among the accessions. The traits measured (anthesis date [AD], plant height [PH], biomass yield [BY], and moisture content [MC]) were all significantly different (P<0.05) among accessions. Morphological marker clustered the accessions into five groups based on PH, MC and AD. The three traits accounted for 92.5% of the variation. There were four and five groups based on SRAP and SSR data respectively classifying accessions mainly on their origin or breeding history. The observed difference between SSR and SRAP based clusters could be attributed to the difference in marker type. SSRs amplify any region of the genome whereas SRAP amplify the open reading frames and promoter regions. Comparing the three marker-type clusters, the markers complimented each other in grouping accessions and would be valuable in assisting breeders to select appropriate lines for crossing. In evaluating QTLs that are associated with bioenergy traits, 165 recombinant inbred lines (RILs) were planted at four environments in Nebraska. A genetic linkage map constructed spanned a length of 1541.3 cM, and generated 18 linkage groups that aligned to the 10 sorghum chromosomes. Fourteen QTLs (6 for brix, 3 for BY, 2 each for AD and MC, and 1 for PH) were mapped. QTLs for the traits that were significantly correlated, colocalized in two clusters on linkage group Sbi01b. Both parents contributed beneficial alleles for most of traits measured, supporting the transgressive segregation in this population. Additional work is needed on exploiting the usefulness of chromosome 1 in breeding sorghum for bioenergy.

Sorghum: An Ancient, Healthy And Nutritious Old World Cereal, United Sorghum Checkoff Program, John Lindsay Jan 2010

Sorghum: An Ancient, Healthy And Nutritious Old World Cereal, United Sorghum Checkoff Program, John Lindsay

INTSORMIL Scientific Publications

Sorghum is Africa’s contribution to the small number of elite grains that supply about 85% of the world’s food energy. Only four other foods rice, wheat, maize, and potatoes are consumed in greater amounts by the human race. Sorghum is the dietary staple of more than 500 million people in more than 30 countries of the semi arid tropics, thus being one of the most familiar foods in the world (Board on Science and Technology for International Development, 1996). Sorghum is a truly ancient grain. Dahlberg and Wasylikowa (1996) reported on sorghum remains found in the Nabta Playa archaeological site …
