There are hundreds of varieties in general breeding, and then after ten or twenty years of cultivation and improvement, the last good variety is selected.
185 is the number of breeding 185 ... As for Wen, it is the name of Wensu County. Wen 185 is the best paper-coated walnut at present. Only Wensu County has planted it, and all other places are 185 instead of Wen 185. There are differences in skin thickness and kernel yield.
Xin 2 is the best walnut with the highest kernel yield.
The new 33 is 343, and the number at that time was 343. This is characterized by selling well, being big and round.
If it is a standard, the current standard of temperature 185 is that the shell thickness is less than 0.8 mm If it exceeds this thickness, it can only be called 185, not 185. In other words, you can only make thin skin, not paper skin.
The standards of new 2 and 343 only look at varieties, and there is no requirement for thickness and kernel rate.
