To achieve a bio‐based economy, it is necessary to consider variability within a feedstock population. We must understand the range of key phenotypic characteristics when selecting economically advantageous genotypes for domestication in an optimized supply chain. In this analysis we measured cell‐wall composition traits in a large natural variant population of Populus trichocarpa. The results were combined with agronomic growth data from the matching genotype to conduct various techno‐economic analyses, evaluating the impacts of physical and compositional variability and determining the ultimate phenotypic drivers for yield and economic metrics. Here we show that, although ethanol yield per land area per year and minimum fuel selling price were most strongly impacted by tree size, when considering the largest 25% of trees, size and carbohydrate content were nearly identical influences on minimal fuel selling price, highlighting the need to focus on both size and carbohydrate content in selecting economically optimal feedstocks. © 2020 The Authors.

生物能源作物的产量和组成变化的经济影响：毛果杨

为了实现基于生物的经济，有必要考虑原料种群的可变性。在一个优化的供应链选择用于驯化经济上有利的基因型时，我们必须了解的关键表型特征的范围内。在这项分析中，我们测量了毛果杨的大量自然变异种群的细胞壁组成特征。。将结果与匹配基因型的农艺学增长数据相结合，进行各种技术经济分析，评估物理和成分变异性的影响，并确定产量和经济指标的最终表型驱动因素。在这里，我们表明，虽然每年每土地面积的乙醇产量和最低燃料销售价格受树木大小的影响最大，但当考虑最大的25％树木时，大小和碳水化合物含量对最低燃料销售价格的影响几乎相同。在选择经济上最佳的原料时，需要同时关注大小和碳水化合物含量。©2020作者。化学工业协会和John Wiley＆Sons，Ltd出版的生物燃料，生物产品和生物精制
