Evaluation of Common Bean Germplasm Lines for Resistance to Angular Leaf Spot (Phaeoisariopsis griseola (Scac.) Ferraris) Under High Altitude Conditions of Gurez Valley

Dar WA*, Parry FA, Khan MM

During kharif season of years 2017 and 2018 field screening of sixteen common bean germplasm lines against angular leaf spot (ALS) under natural disease epidemic conditions could identify for resistance to angular leaf spot (ALS) in common bean have relied on a range of sources of resistance. However, due to occurrences of many different races of the pathogen, sources of resistance may not always be effective in all the regions. The present study was conducted to identify new sources of resistance to ALS. A total of sixteen new germplasm lines were evaluated for resistance. The results observed that the response germplasm lines to ALS during the two years were similar. The results further revealed that under epiphytic conditions only one germplasm viz., SR-1 exhibited resistance reaction.
