The present studies were aimed to evaluate 490 maize entries for resistance against turcicum leaf blight (TLB) disease in randomized block design using a check at Agricultural Research Station, Karimnagar, Telangana State, India during rabi (November,2021 Febrauary,2022) and kharif (July,2022 October,2022). Out of 213 lines 2021−2022,16 promising viz.,KML-21,KML-24,KML-33,KMH-388,KMH-275,KMH-373,KMH-478,KMH-370,KMH-257,KMH-393,KMH-340,KMH-131,KMH-41,KMH-36, SAMRAT KMH- 64 identified as resistant ,157 recorded moderately resistant,38 susceptible CM-202 entry was 80.42 per cent index (PDI).Out 277 2022,3 viz.,KMH-804,KMH-751 KML-86 disease,132 resistant,one line noticed with high 81.42 severely affected by rated kharif, 2022.
