GIANT LINK - Genetic improvement of Miscanthus to be a sustainable feedstock for bioenergy in the UK (LK0863)
Biomass-derived energy is renewable and low carbon. Low input perennial biomass crops such as the giant grass Miscanthus are a useful source of raw material needed for producing bioenergy in the UK and elsewhere. Energy crops also provide an important option for farmers, providing environmental benefits, such as GHG mitigation and soil carbon sequestration (depending on previous land use). Miscanthus requires low inputs owing to the efficient recycling of nutrients from above ground biomass to below ground rhizomes in the autumn and winter, with harvest of above ground biomass in late winter or early spring. Commercial uptake has suffered from lack of diverse varieties and poor farmer economics.
Analysis of G X E effects in terms of yield and composition on novel seed hybrids is underway and being taken forward in succession projects with UK and EU funding
Above: MiscanFor model v2016 (Hastings et al.) annual harvestable yields for Mxg. As new GIANT (“GNT”) hybrids mature, this map will be revised.
