SUMMARY

Walnut trees grouped in nuts are actually reproduced as clonal which is vegetative material. Generally, seedlings are firstly obtained by walnut seed that is planted in the nursery. Then cultivars are grafted onto seedling rootstocks, and walnut orchards are established by this grafted young trees. As known, clonal samplings are preferred at modern orchards by orcharder. Because walnuts trees grafted on rooted cuttings have performed well as clonal when compared to seedlings. However, sampling production grafted on clonal walnut rootstock is not still be used in walnut orchards extensively. Because of this, seedling is largely be used recently. In addition to this, walnut growers have not knowledge enough about walnut varieties and tips which are be evaluated as seedling rootstock. In spite of this, the lose of a plenty of walnut seeds are be occurred in each year.
