Abstract

Identification and transfer of desirable genes from WILD RELATIVES to crop species is one of the breeding solutions for producing resistance to pathogens and pests. This study was conducted to evaluate crossability and the response to Pythium ultimumin three species of the genus Carthamus. To assess response to the pathogen, eight cultivated safflower (Carthamus tinctorius L.) genotypes, two ecotypes of wild species C. oxyacanthus collected from Tehran and Isfahan, and one ecotype of wild species C. lanatus collected from Golestan province as sub factor were cultured on pathogen-free and infested medium with ZOOSPORE suspension of P. ultimum as main factor in a split plot design with 4 replications. Suspension of 105 ZOOSPORE per milliliter was used for inoculation. At the pathogen-free media, SEED germination of cultivated and C. lanatus genotypes was higher than 90%, but at the infested media just cultivated genotypes had germination to this extent. The crossability experiment shows that, success in interspecific hybrid SEED production is highly depended on choosing the SEED producing parent. In the cross of cultivated species with C. oxyacanthus, more hybrid SEED was obtained when C. oxyacanthus was female parent. Produced SEEDs on the cross of cultivated species and C. oxyacanthus had enough germination ability, but it was nothing for SEEDs obtained from cross of cultivated species and C. lanatus. Resistance of C. oxyacanthus to the pathogen Pythium and success in hybrid SEED production show the potential of this species for transferring of resistance and other favorable traits to cultivated safflower.
