Abstract :This selection study was conducted to determine the walnut genotypes with superior characteristics grown from seeds in Ereğli and Halkapınar districts of Konya province and Ayrancı district of Karaman province between 2019-2022. In 2021 on the fruits taken, 8 genotypes in total, including 5 genotypes in shelled walnuts and 4 genotypes in kernels (1 genotype received high scores in both shelled and kernel walnuts) were found to be promising. In 8 genotypes selected, the shelled weight is 10.66-26.31 g, the kernel weight is 5.32-9.82 g, the kernel percentage is 37.33-57.91%, the shell thickness is between 1.06-1.90 mm, the shell color is "light” in 1 genotype, "moderate” in 4 genotypes, "dark” in 3 genotypes, kernel color is in 1 genotype "extra light”, "light” in 7 genotypes, remove of kernel from the shell was "easy” in all genotypes. Shell adhesion was "good” in all genotypes, cracking of the shell was detected "easy” in 7 genotypes, "moderate” in 1 genotype, shell texture was "smooth” in 3 genotypes, "moderate” in 4 genotypes, and "rough” in 1 genotype. Remove of kernel from the shell was determined "easy” in all genotypes. Kernel fill and healthy kernel percentage was determined as 100% in all genotypes. At the end of the research, 6 of the selected genotypes showed homogamy, 1 showed protogeny and 1 showed protandry flowering properties.
