Genotypes were significantly different in terms of all the studied traits, and genotypes no. 5, 9 and 10 had higher yield than Reihan03. The studied genotypes were clustered in five groups the fifth group, consist 9.1% of genotypes, had the highest yield (1972 Kg/ha). Regression analysis showed that traits including days to ripening, length of the final internode, thousand kernel weight, plant height, and spike number per m2 accounted for 98.8% of the changes. Furthermore, there was a negative and significant (P M3 ER -
