Summary
The world collection of cultivated safflower, C. tinctorius L., containing about 2000 lines, was screened for resistance to one of its severest insect pests, the safflower fly, Acanthophilus helianthi R. Only 3 lines with low infestation levels were found but they cannot be considered reliable sources of resistance. Nine wild Carthamus species were also tested. Several species contained fly-free accessions, among them two species which are closely related to cultivated safflower, viz C. flavescens Willd. and C. palaestinus Eig. Breeding for earliness which will lead to more escapes, appears the best approach towards minimizing fly damage in the Mediterranean area.
