Abstract

This investigation was conducted at Qlyasan Agricultural Research Station, Faculty of Agricultural Sciences, University of Sulaimani (Lat 35° 34 307   ; N, Long 45° 21 992   ; E, 765 masl) during (2013 – 2014) to estimate the simple correlation coefficient among characters and to determine the path analysis between grain yield and their components. Using five parents and their 20 crosses made by 5x5 full Diallel cross system in this experiment. The results confirm the presence of highly significant and positive correlation between grain yield with No. of spikes / plant , weight of spikes / plant , 1000 grain weight and biological yield , while significant and positive correlation between grain yield with plant height and average grain weight / plant were observed . Maximum positive direct effect on grain yield recorded by No. of spikes / plant with 0.538. Maximum positive indirect effect in grain yield recorded by weight of spikes / plant via No. of spikes / plant with 0.331.
