“Food and Bioenergy: Reviewing the Potential of Dual‐Purpose Wheat Crops”

摘要: Within the bioenergy debate, ‘food vs. fuel’ controversy quickly replaced enthusiasm for biofuels derived from first-generation feedstocks. Second-generation offer an opportunity to produce fuels dedicated energy crops, waste materials or coproducts such as cereal straw. Wheat represents one of most widely grown arable crops around world, with wheat straw, a potential source biofuel feedstock. straw currently has limited economic value; hence, cultivars have been bred increased grain yield; however, development second-generation production, utilization biomass provides and fuel’. Reviewing evidence dual-purpose optimized food we present holistic assessment ideotype cultivar (DPC). An ideal DPC would be characterized by high yields, digestibility (i.e. yield potential) good lodging resistance. Considerable variation in these traits exists among current cultivars, facilitating selection improved individual traits; increasing could potentially negative trade-off impacts on resistance, reducing feasibility single ideotype. Adoption alternative management practices increase digestibility, albeit are also associated trade-offs traits. Benefits using DPCs include reduced logistics costs along feedstock supply chain, but practical barriers differential pricing likely reduce financial incentive farmers growing higher ‘biofuel-quality’ cultivars. Further research is required explore relationships quantify benefits; this will help determine whether stakeholders chain invest that provide fuel potential.
