Seventy sunflower genotypes consisting of inbred, hybrid and open-pollinated varieties were dehulled by a rotor mill. The analysis of variance for decortication demonstrated a significant difference in ease of dehulling among different sunflower genotypes. Achene characters of size, oil percentage, color, wax percentage of the hull and percent hull were studied to determine their interrelationships and to establish the relative importance of each as they affected decortication. Correlation coefficients were calculated for all possible combinations of achene characters. The correlation between decortication and coller was not significant. Decortication was negatively correlated with oil and wax percentage (r= -0.54 and -0.56, respectively) and positively corre-lated with percent hull and achene size (r= 0.42 and 0.57, respectively), when all 70 genotypes were considered together. None of these characters were significantly correlated with decortication in the nonoilseed genotypes, and sull percent was not significantly correlated with decortication in the oilseed genotypes. Path coefficients were used to analyze multiple correlation coefficients from the best multiple regression model and to establish the relative importance of variables as they affected decortication. Achene size was the most important character in the oilseed genotypes. Oil and wax percentage were shown to have less important effects on decortication. The negative correlation between oil percentage and decortication may pose a problem for the ...
