“…Of all Saccharum species, S. spontaneum has very wide geographic distribution from tropics to subtropics, resulting in the most diverse germplasm, which has been substantially used in sugarcane breeding programs (Ming et al, 2006), and are being deployed in the development of bioenergy cultivars (Tew and Cobill, 2010). Genetically diverse germplasm of S. spontaneum can effectively contribute to disease resistance, cold tolerance, insect resistance, and tillering potential to new breeding products.…”

“…More recently, S. spontaneum crossed with selected sugarcane clones (S. officinarum or Saccharum hybrids) has been deployed to produce early generation hybrids selected for sugar-fiber energy cane or fiber-only energy cane as a bioenergy crop (Tew and Cobill, 2010). Hybrids are selected for adaptation to more temperate environments and production of higher biomass yields compared to traditional sugarcane cultivars.…”

ABSTRACT. Saccharum spontaneum is a wild sugarcane species that is native to and widely distributed in China. It has been extensively used in sugarcane breeding programs, and is being tested for the development of bioenergy cultivars. In order to provide basic information for the exploitation of this species, we analyzed genetic variation among and within native S. spontaneum populations collected from Sichuan, China. Eighty plants from nine native populations were sampled. Twentyone sequence-related amplified polymorphism primer pairs generated 235 clearly scorable bands, of which 185 were polymorphic (78.7%). Nei's genetic diversity was 0.2801 and Shannon's information index was 0.4155 across the populations. Genetic diversity parameters, G ST value (0.2088) and N m value (1.8944), showed that the genetic variation within populations was greater than that among populations. In the cluster analysis, one major grouping was formed by populations from Ya'an and another one by populations from Sichuan basin; a population from Baoxing formed a single cluster. In order to fully comprehend the genetic diversity of cold-tolerant local germplasm in this species, germplasm should be collected from the heterogeneous environments along the northern regions of this species' distribution. The germplasm that we collected should be a valuable resource for Saccharum breeding.

“…Approximately, 65 to 70% of global sugar production in the form of sucrose is derived from sugarcane (FAO, 2003). The potential of sugarcane as an important energy crop was argued because of the advent of large-scale sugarcane-based ethanol production in Brazil (Tew & Cobill, 2008).…”

“…Of the other four species, S. robustum, S. barberi, and S. sinense have also provided minor contributions to the breeding of some modern sugarcane cultivars (Cheavegatti-Gianotto et al, 2011 The breeding of sugarcane as a dedicated biomass crop called "energy cane" can be categorized into three strategies with different objectives: the "sugar model", the "sugarand-fiber model", and the "fiber-only model". The fiber yield of energy cane is important because of its use for electricity generation, cellulosic ethanol production, and so forth; fiber is considered a by-product in the sugar and sugar-and-fiber models or the main product in the fiber-only model (Tew & Cobill, 2008). In the sugar model, improved sugar yield and sugar content are the main foci, so traditional sugarcane cultivars can be used.…”

“…Ratios of 1:8 are estimated for tropical sugarcane processed for ethanol, with ratios of 1:3 estimated for cane grown under more temperate conditions. 69,70 Although additional work is necessary to develop sugarcane varieties with increased cold and pest tolerance, the high energy density of the cane has maintained interest in developing it as an energy crop. Sugarcane is known to be a non-emitter of isoprene, 71 but its emissions profile for other BVOC species is unknown.…”

Air-quality and Climatic Consequences of Bioenergy Crop Cultivation

Bioenergy is expected to play an increasingly significant role in the global energy budget. In addition to the use of liquid energy forms such as ethanol and biodiesel, electricity generation using processed energy crops as a partial or full coal alternative is expected to increase, requiring large-scale conversions of land for the cultivation of bioenergy feedstocks such as cane, grasses, or short rotation coppice. With land-use change identified as a major contributor to changes in the emission of biogenic volatile organic compounds (BVOCs), many of which are known contributors to the pollutants ozone (O3) and fine particulate matter (PM2.5), careful review of crop emission profiles and local atmospheric chemistry will be necessary to mitigate any unintended air-quality consequences. In this work, the atmospheric consequences of bioenergy crop replacement are examined using both the high-resolution regional chemical transport model WRF/Chem (Weather Research and Forecasting with Chemistry) and the global climate model CESM (Community Earth System Model). Regional sensitivities to several representative crop types are analyzed, and the impacts of each crop on air quality and climate are compared. Overall, the high emitting crops (eucalyptus and giant reed) were found to produce climate and human health costs totaling up to 40% of the value of CO2 emissions prevented, while the related costs of the lowest-emitting crop (switchgrass) were negligible.ii Acknowledgements
