Abstract:Safflower (Carthamus tinctorius L.) is one of the important oilseed and bio-energy crops. All of the safflower cultivars in the world have diploid genomes (2n= 2x= 24). In this research, autotetraploidy induction in safflower was performed by colchicine treatments to the emerging shoot tips at the cotyledonary stage. As a result of flow cytometric analyses performed in the C2 progenies, autotetraploids (4x= 48) had DNA content of 4.88 pg 2C-1, while diploids (2x= 24) had 2.29 pg 2C-1. The autotetraploids in C2… Show more
