New faba bean germplasm with multiple resistances to Ascochyta blight, chocolate spot and rust diseases
Faba bean is one of the oldest crops that originated in the Fertile Crescent and is now distributed around the world and produced under different agro-climatic conditions. It is mainly cultivated in high rainfall and irrigated areas which are favorable for the development of foliar diseases causing severe crop losses. The purpose of this study was to identify new sources of resistance to the three key foliar diseases. A total of 2000 accessions, breeding lines and populations were screened for resistance to chocolate spot, Ascochyta blight and rust diseases from 2005 to 2012, at Lattakia Station, Syria. A total of 30 lines combining Ascochyta blight, chocolate spot and rust resistance were identified from accessions collected from China, Italy, Jordan, Lebanon and Spain. These new sources of resistance will enhance the development of faba bean breeding lines with combined resistance to the three foliar diseases.
