Introgression potential between safflower (Carthamus tinctorius) and wild relatives of the genus Carthamus.

ABSTRACT:

Background

Safflower, Carthamus tinctorius, is a thistle that is grown commercially for the production of oil and birdseed and recently, as a host for the production of transgenic pharmaceutical proteins. C. tinctorius can cross with a number of its wild relatives, creating the possibility of gene flow from safflower to weedy species. In this study we looked at the introgression potential between different members of the genus Carthamus, measured the fitness of the parents versus the F1 hybrids, followed the segregation of a specific transgene in the progeny and tried to identify traits important for adaptation to different environments.

Results

Safflower hybridized and produced viable offspring with members of the section Carthamus and species with chromosome numbers of n =
