Sorghum Improvement for Energy Production
نویسندگان
چکیده
Sorghum (Sorghum bicolor ( L. ) Moench ) has emerged as a leading candidate for biomass utilization among energy crops due to high yield potential, ease o f culture and wide adaptibility. Previously, enormous diversity present in the germplasm has been manipulated by sorghum breeding programs primarily to produce grain, syrup or forage. Development of sorghums for energy utilization will require a similar effort but should be more rapid based on current knowledge of the genetics of desirable characteristics. Results from yield trials of sweet, grain and grain x sweet sorghum hybrids demonstrate that partitioning carbohydrate into both grain and stalks can increase the suitability o f the crop for energy. Fresh weight biomass yields in excess of 60 Mg ha -1 and ethanol yields in excess o f 5000 litres ha -~ are possible from the use of improved cultivars.

Bioenergy sorghum is targeted for production in water-limited annual cropland therefore traits that improve plant water capture, water use efficiency, and resilience to water deficit are necessary to maximize productivity. A crop modeling framework, APSIM, was adapted to predict the growth and biomass yield of energy sorghum and to identify potentially useful traits for crop improvement. APSIM ...

متن کاملLife-cycle energy use and greenhouse gas emissions of production of bioethanol from sorghum in the United States
BACKGROUND The availability of feedstock options is a key to meeting the volumetric requirement of 136.3 billion liters of renewable fuels per year beginning in 2022, as required in the US 2007 Energy Independence and Security Act. Life-cycle greenhouse gas (GHG) emissions of sorghum-based ethanol need to be assessed for sorghum to play a role in meeting that requirement. RESULTS Multiple sor...
متن کاملImprovement of Sorghum through Transgenic Technology
Sorghum is the fifth most important cereal crop in the world. It is largely grown on marginal soils with residual moisture where other major cereals cannot be grown due to inadequate water. Sorghum is a multipurpose crop and the species shows great diversity. For a large part of Asia and Africa, sorghum’s grain is used as food and its stalk as fodder and feed. In rest of the world, sorghum is c...
