Task 1: Feedstock Development

4/5/2012 11:28:33 PM

Task 1.1. Development of genetic markers for cold tolerance, biomass yield and composition.

    Expressed Sequence Tag-derived Simple Sequence Repeats and Single Nucleotide 
    Polymorphism will be obtained from the SUCEST date bank and amplicon sequences from 
    S. Spontaneum
, S. Officinarum and Miscanthus (for genes related to cold tolerance and 
    biomass quality).

Task 1.2. Evaluate unselected Saccharum x Miscanthus BC1 populations in more northerly locations.

    We now have new germplasm with more diverse heritage derived from S. Spontaneum x 
    sugarcane cultivar F1s crossed to Miscanthus for evaluation and selection. Miscanthus is 
    recognized for its cold tolerance, making it more favorable for northern locations.

Task 1.3. Feedstock quality analysis and NIR calibration.

    Variability in fiber composition will be assessed using SpectraCane Near Infrared (NIR) 
    Spectroscopy to rapidly screen entries in breeding programs.

Task 1.4. Make targeted crosses in the breeding program based on feedback from agronomic performance, fiber quality and chemical composition analysis.

    Besides the obvious data gathered by breeders on agronomic and fiber quality traits, plant 
    materials will also be processed into several chemical streams, and these data will be made 
    available to the breeders.

Task 1.5. Planting and selection of seedling populations for expansion of the geographic growing region.

    Seedlings raised at the USDA, Houma, will be transplanted at Houma. Trials will be 
    established on marginal lands and carried out using minimal inputs, e.g., fertilizers, 

Task 1.6. Evaluate advanced energycane materials from the existing breeding program in more northerly locations.

    Advanced energycane clones currently under development and subsequently advanced 
    clones selected in this project will be evaluated in replicated field trails at multiple northern 
    locations between Bunkie and St. Joseph, La.

Task 1.7. Monitor and evaluate the incidence of pests, diseases or weeds in energycane trials.

    Energycane experiments will be visually monitored by LSU AgCenter and USDA plant 
    pathologists, entomologists and weed scientists to determine the incidence and severity 
    of pests, diseases or weeds.
