World nuts production is about 900 thousand tons compared to the average in recent years, and this production tends to constantly increase. The most important varieties of nuts have been discovered by selection based on producer observations from a wide population in natural cultivation areas. It can be given the best example of the 'Tombul' variety with superior quality. The main characteristics taken into consideration in nuts are focused on the fruit and productivity characteristics, the morphological and phenological characteristics, the resilience and the primacy. Although Turkey and Italy are the largest producer countries in the past few years, the most extensive work on nuts is carried out in the U.S. In recent years, studies based on molecular markers techniques have been focused and significant advances have been. "Gasaway" was developed as a new species resistant to EFB, and in subsequent studies these resistance genes were used.

It requires diverse, comprehensive and sustainable work. It is essential to obtain high-performance, high-quality, biotic and abiotic conditions varieties for different ecologies. It is also desired to develop varieties that fit different consumption habits. In addition, it is also important for the recreational design of the landscape.
