多光谱成像，是快速、强劲的管理基因库品系的方法，比较典型的是Videometer多光谱成像系统。该无损技术可测量不同种子表型，例如在数秒内完成种子尺寸、形状和颜的测量(图1a)。该设备还可进行种子净度测量，例如可比较繁殖种子与原种子进行对比。在基因库网站分享基础种子表型信息将对种子使用者基于目标选择正确品系有很大帮助。多光谱成像，例如Videometer拍摄的多光谱图像，在作物健康研究中非常有用。种子红色、紫色或其它任何颜色种皮可能含有提升健康的酚类化合物。与传统操作昂贵、人员成本高、需破坏种子的生物化学分析相比，多光谱成像分析可提供基于颜色性状的、成本低的可靠数据分析。 

Multispectral imaging, through the use of an instrument such as the Videometer, is a fast and robust approach helpful for managing genebank accessions. This non-destructive technique can measure various seed phenotypes, e.g., seed size, shape, and color within a few seconds (Figure 1a). It can also perform seed purity tests to compare regenerated seeds with the original seeds. Sharing basic information of seed phenotypes through the genebank website would be helpful for seed users to choose the right accessions based on their purposes. Multispectral imaging, such as that obtained by the Videometer, is very useful in healthier crops research programs too. Red, purple or any other colored pericarps in seed contain health promoting phenolic compounds . Comparing with conventional biochemical assays that require expensive operational and labor costs as well as destruction of many seeds, multispectral imaging analysis can provide reliable data of color -based traits with minimal cost.
