Vitamin B and its derivatives possess diverse physiological functions and are essential micronutrients for humans. Their variation in crops is important for the identification of genetic resources used to develop new varieties with enhanced vitamin B. In this research, remarkable variations were observed in kernels of 156 maize inbred lines, ranging from 107.61 to 2654.54 μg per 100 g for vitamin B1, 1.19-37.37 μg per 100 g for B2, 19.60-213.75 μg per 100 g for B3, 43.47-590.86 μg per 100 g for B5, and 138.59-1065.11 μg per 100 g for B6. Growing inbreeds in Hainan and Hebei provinces of China revealed environmental and genotype interactions among these vitamins and the correlations between them in maize grain. Several inbred lines were identified as good sources of vitamin B and promising germplasms for maize breeding, namely By855 and Si273 are overall rich in all the studied vitamins, and GY386B and CML118 are specially enriched with derivatives of vitamin B6. The present study can assist maize breeders with germplasm resources of vitamin B for biofortification to offer people nutritious foods.
维生素B及其衍生物具有多种生理功能，是人类必需的微量营养素。它们在作物中的变异对于鉴定用于培育维生素B含量更高的新品种的遗传资源很重要。在本研究中，观察到156个玉米自交系籽粒中存在显著变异，维生素B1含量为每100克107.61至2654.54微克，维生素B2为每100克1.19至37.37微克，维生素B3为每100克19.60至213.75微克，维生素B5为每100克43.47至590.86微克，维生素B6为每100克138.59至1065.11微克。在中国海南省和河北省种植自交系揭示了这些维生素之间的环境和基因型相互作用以及它们在玉米籽粒中的相关性。几个自交系被鉴定为维生素B的良好来源和玉米育种中有前景的种质，即By855和Si273总体上富含所有研究的维生素，而GY386B和CML118特别富含维生素B6的衍生物。本研究可为玉米育种者提供维生素B种质资源用于生物强化，从而为人们提供营养丰富的食物。
