Online published on 14 February, 2012. Abstract Evaluation of 425 accessions of fodder Sorghum comprising of 219 indigenous, 148 exotic accessions and 58 advanced breeding lines for multiple foliar disease resistance under natural disease incidence conditions was done. 43 accessions were identified as resistant and moderately resistant to all the 4 foliar diseases, viz., anthracnose caused by Colletotrichum graminicola, zonate leaf spot caused by Gloeocercospora sorghi, sooty stripe caused by Ramulispora sorghi and leaf blight caused by Exserohilum turcicum. Critical evaluation of 43 accessions under natural and epiphytotic condition as well as artificial inoculation led to identification of three accessions namely IG 02–495, SGS-81 and SGS-114 as highly resistant to all the four foliar diseases.
