Özet:

Bean rust disease is one of the most important fungal diseases of limiting the yields of common bean all over the world.  The most effective and the most harmless methods against the bean rust pathogen are breeding and use of the resistant varieties. Resistance to diseases can be previously determined in breeding programs with the critical data obtained from molecular markers developed in recent years. In this study, resistance against bean rust was investigated by SCAR markers in 43 registered bean varieties, which is widely cultivated in Turkey. As a result, PCR studies performed with 4 different markers (SA14, SI19, SBC6, AE19) which characterize the genes related to resistance revealed that some varieties have the genes linked to the resistance. In addition to revealing the current status of the registered varieties, the results of the study are expected to support new breeding programs.
