Abstract :In this research, a diallel cross consisting of genetically diverse six parents insert ignore into journalissuearticles values(Es-8517, Emek-16, Ekak-7, Emek-21, Ekay-1, Emek-24); was used, aimed to obtain estimates of the gene action in terms of plant height, first branches height, head diameter, 1000 seed weight, oil content, oil yield of per plant in safflower by using Jinks-Hayman type analyses. This study was conducted Transitional Zone Agricultural Research Institute Eskisehir, Turkey during 2016 and 2017. According to the results of all diallel crosses, environmental variance insert ignore into journalissuearticles values(E);, additive gene variance insert ignore into journalissuearticles values(D);, dominance gene variance insert ignore into journalissuearticles values(H1);, insert ignore into journalissuearticles values(H2); and the value of interaction of additive x dominance gene variance effect insert ignore into journalissuearticles values(F); were found significant statistically studied traits expect head diameter. Of all the traits studied, being larger dominant gene variances insert ignore into journalissuearticles values(H1); than the additive gene variances insert ignore into journalissuearticles values(D); and negative D-H1 value indicated the more important role of dominant genes. Beside of these, positive F value shows that dominant alleles are greater than the number of recessive alleles. Result of Wr, Vr graphics indicated partial dominancy for the first branch height, head diameter, and over dominancy for the rest of the studied traits. It was determined that plant height, first branches height, head diameter, 1000 seed weight, oil content, oil yield of per plant had low narrow heritability values. According to results to obtain superior plants in this hybrid population to perform single plant selection in F3 and F4 generations would be more appropriate.
