The influence of growing conditions in North Dakota on grain yield and seed composition was evaluated for industrial hemp varieties (Cannabis sativa L.) grown in North Dakota, USA. Average grain yield across varieties was 2138 kg ha⁻¹. Crude protein content of undehulled industrial hemp flour from 10 varieties ranged from 32.7% to 35.9%; and oil content ranged from 24.3% to 28.1%. All industrial hemp flours were excellent natural sources of iron (46.7%), manganese (169.1%), copper (29.0%), zinc (28.2%), phosphorus (41.0%), and magnesium (33.7%) on a per serving basis (30 g per serving) for percent recommended daily intake (% RDI). Oils from most of the varieties differed significantly for the fatty acid (FA) profile. The n6/n3 ratio ranged from 3.2 to 5.1. Principal component analysis (PCA) suggested that CFX‐2 and CRS‐1 grew well in North Dakota based on grain yield, flour, and oil quality. In this study, the chemical composition of flour was not influenced by crop year; but crop year did effect the nutritional mineral composition. These results may have important implications for the use of industrial hemp in food applications.

基因型x环境对美国北达科他州种植的工业大麻（Cannabis sativa L.）品种的产量和种子化学组成的环境影响

在美国北达科他州种植的工业大麻品种（Cannabis sativa L.）评估了北达科他州生长条件对谷物产量和种子组成的影响。各个品种的平均谷物产量为2138 kg ha ^-1。10个品种的未脱皮工业大麻粉的粗蛋白含量为32.7％至35.9％；含油量在24.3％至28.1％之间。每份工业大麻粉都是优质的天然铁（46.7％），锰（169.1％），铜（29.0％），锌（28.2％），磷（41.0％）和镁（33.7％）的天然来源（每份30克），以建议的每日摄入量百分比（RDI％）为准。来自大多数品种的油的脂肪酸（FA）特征差异很大。n6 / n3的比率范围为3.2到5.1。主成分分析（PCA）表明，基于谷物产量，面粉和油品质量，CFX-2和CRS-1在北达科他州生长良好。在这项研究中，面粉的化学成分不受作物年限的影响。但是作物年份确实影响了营养矿物质的成分。
