Because it ripens late, it is called LUN Ye. It is said that the origin of "Wan Lun" is related to the technical innovation team of late-maturing citrus. Since 2005, after several years' efforts, the technical innovation team of late-maturing citrus in Hubei Province has carried out many experiments in Zigui experimental base, and continuously selected, optimized and cultivated a new variety of "Wan Lun". Wan Lun's name came from this. Wan Lun navel orange is a late-maturing navel orange variety, which matures in the middle and late March of the following year.
