Based on a comprehensive study of 100 samples of safflower from the world gene pool for three years, the results of the selection of primary sources for different areas of selection (growth period, 1 plant yield, 1000 seed weight, oil content) are covered. Primary sources for different areas of selection have been identified on the basis of the study of the early maturity of seed samples, seed size, oil content in seeds, the study of the correlation between complex traits and the main economic traits. Correlation between major crop characteristics such as safflower vegetation period, main stem height, number of primary, secondary and lateral branches, total number of pods per plant, number of seeds per pod, plant yield, weight of 1000 seeds, oil content in seeds were studied. The highest correlation was found between the length of the main stem and the length to the first branch (r = 0.84) and the total number of baskets in one plant with the number of secondary side branches in it (r = 0.90).
