| Abstract | ||
| A study was carried out in the agricultural filed/ college of Agric. univ . of Tikrit for estimation of some genetic parameters and path analysis to determination characteristics that have avetal role on yield, three distances between plants :(15,25,and 35cm) used as main plots and five genotypes :( AL-mais , Jordanian , 400 , 540 and 2081) as sub plot in split plot design with three replications . Results showed significant positive phenotypic and genotypic correlation between yield and its components, capitula plant, capitulum diameter had big direct effect on yield , beside high indirect effect of 1000 seed weight with yield components . Heritability estimate was 76.7 for number of capitula plant and expected genetic advance were (19.89 ,19.34 and 32.5%) for seed yield number of capitulo plant and capitulum diameter respectively therefor we can used the last two characters as a selection criteria in breeding programs to improve safflower seed yield . | ||
