At this website you will find links to walnut related Events, Articles, Books, Titles of PhD and MSc theses,

Researchers, Varieties, Videos, Photos and Links to other walnut related URLs. Please visit the “Researchers” list and let me know if your address is missed.

I would like to express my appreciation to my colleagues in different countries for providing information particularly regarding their walnut varieties.

I would appreciate it if you could also provide us with any additional information you are willing to share about walnut so we can use it to further improve this website. This will help us all extend and expand our collaborations and improve our knowledge about WALNUT.

PS. “If you have a walnut and I have a walnut and we exchange the walnuts then you and I will still each have one walnut. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas” – Adopted from George Bernard Shaw (1856 - 1950), Irish dramatist, novelist and critic.
