This study was carried out to discuss the use of certain nut characteristics as a selection criterion, and reveal the importance of the degree of repeatability in selection breeding. The degrees of repeatability for nut weight (NW), kernel weight (KW), shell thickness (ST), nut length (NL), nut suture (NS) and nut cheek (NC) were found to be high. It has been concluded that the probability of the continuity of the superiority on following years is high for individuals having higher ratings for the above mentioned characters.
