In this study; the local varieties (Nermin Cin) and 34 local popcorn populations which obtained from Turkey's different regions were used to determine the popping traits and grain quality of populations by growing in Kahramanmaraş conditions. The differences among examined features of genotypes, years and genotype x year interactions were statistically significant (p < 0.01). The varieties among popcorn genotypes were 70.177-96.017 cm3 g-1 for popping volume; 3.767-22.658% for popping grain ratio; 4.150-29.823% for un-popping grain ratio; 9.882-11.537% for protein ratio; 68.727-72.920% starch ratio; 4.230-5.608% for fat ratio and 88.050-89.837% for dry matter ratio. The highest and the least values of the features investigated in terms of import of popping criteria and grain quality features were obtained 5 and 32 number populations for the popping volume, 16 and 26 number populations for the ratio of popping grain, 20 and 6 number populations for the starch ratio of grain respectively. The accuracy of reseach has been showed to create relation groups each other and rich variations in terms of features studied on popcorn genotypes, because the maize plant has an open dusty genetic structure. As a result of this research, the genetic variation of popcorn populations in the country was been studied to determination.
