Particularly the green shoot heads damaged from cold weather, when the temperature decrease -2-3°C, after starting of walnut vegetation. Turkey’s walnut production and yield were dramatically decreased during the late spring frost in 2013. 83 genotypes were marked in Van Lake zone during 2013. The present study carried out during 2014-2015 and the late vegetates walnut populations were investigated. 25 genotypes were selected based on the seed weights of the walnuts. The seed weights were 11.46-16.25 g, the shell weights were 4.46-8.27 g, the inner ratios were 45.79-61.08 %, the protein ratios were 12.55-21.34 %, total oil ratios were 63.99-69.34 %, humidity ratios were 2.09-3.87% and the ash ratios were 1.33-2.50 %. Additionally, The macro and micro elemental analysis of the seeds were carried out and % 2.44 N, 297.5 mg P, 442.6 mg K, 331.9 mg Mg, 186.8 mg Ca, 169.1 mg S, 1.88 mg Na, 2.58 mg Fe, 2.86 mg Mn, 2.29 mg Zn ve 1.34 mg Cu values were observed.
