Miscanthus x giganteus is the forerunner in the race of viable feedstock options for lignocellulosic bioenergy production. But researchers believe "putting all their eggs in one basket" could be a big mistake. Scientists at the University of Illinois recently reported the first natural occurrence in several decades of Miscanthus hybrid plants in Japan.
M. x giganteus is a sterile triploid (three sets of chromosomes) formed by a natural cross of M. sacchariflorus and M. sinensis. Because it's sterile, it can only be propagated by vegetative division, which is somewhat more difficult than propagating by seed, Stewart said.
