There are several theories about the origin of the name “185 Walnut Inshell”. It is widely believed that the “185” in the name of the walnut does not refer to the size or weight of the walnut, but rather to its variety number. There are many other walnuts named in this manner, such as the “Xin2 Walnut Inshell” and the “Xin33 Walnut Inshell,” which were originally named as variety numbers. In the breeding process, the excellent varieties are finally cultivated and selected through years of selection and technical improvement among many varieties.
The “185 walnut Inshell” is an early-maturing walnut variety selected and bred by Xinjiang forestry researchers in the 1980s through hybridization.

“Wen 185 Walnut Inshell "is suitable for constructing dense and high-yield walnut orchards, and implementing intensive cultivation. The production area of "Wen 185 Walnut Inshell" is Kekeya Town, Wensu County, which is a national level walnut demonstration base with a large planting area of "Wen 185 Walnut Inshell".
