ABSTRACT
plant height.Multiple regression analysis showed that branch height from base(X_2),number of primary branches(X_4),number of effective cones per plant(X_6),number of ineffective cones per plant(X_7),number of grains per cone(X_9),and diameter of primary head(X_(10)) were the main factors affecting flower yield(Y) per plant.Multiple regression equation of flower yield per plant and six characters was Y=-3.037 0+(0.002 7) X_2+0.045 9 X_4+0.074 5 X_6+0.043 2 X_7+0.023 0 X_9+1.148 2 X_(10)(F=21.84~()).The direct effect of number of effective cones per plant was the strongest,followed by diameter of primary head.There were significant differences within the flower yield per plant and the safflor yellow A content of different species.The correlation between the safflor yellow A content and the flower yield per plant was insignificant.Conclusion High-yield and high-quality are compatible in breeding of safflower which is used as herbal medicine.Number of effective cones per plant and diameter of primary head are focused on the high yield breeding and cultivation of safflower species.The plant type of higher flower yield safflower species should have more effective cone numbers,more number of cones,number of branches,number of primary branches,bigger diameter of primary head,moderate plant height,branch height from base,and ineffective cones per plant.Of all accessions,PI 239226,PI 253540,PI 367833,and Jianyang Honghua are outstanding and optimal for cultivating in Sichuan Province.
