Forty inbred lines of maize were indexed against banded leaf and sheath blight (BLSB) caused by Rhizoctonia solani f. sp. sasakii. The lines were artificially inoculated under pot culture conditions. Out of forty, four inbred lines viz., BAJIM08-90-1-6- 1, BAJIM 6128, CML437-B-B, and CML 164 were found highly resistant (HR) with disease score of 1. Bajuara Makka 1, HKI 488, HKI 1105, CML 165, CML 336, CML 439, CML 437, BML 6, CML414, L 292, CML 437-B-B, L 265, BAJIM 95-60-5, CML 460, Sarhad-HSRB, LM 13, VQL 2, CML 169, and HKI 162 were rated as resistant with disease score of 3. The remaining inbred lines were highly susceptible.Keywords

Turcicum leaf blight (TLB) caused by fungus Exserohilum turcicum is most devastating maize foliar disease in North western Himalayan region of the world. The present investigations were carried out to screen the 70 medium maturing maize inbreds against TLB under artificial epiphytotic conditions.. The per cent disease index ranged from 13.3 - 80.0 and area under disease progressive curve was 300.0 - 1591.7 whereas apparent infection rate varied from 0.020 - 0.070. Based on disease rating scale, per cent disease index, AUDPC and apparent infection rate inbreds CML50, CML119, CML577, 36128, CML44 (OP), CML494, 9402-1, Bajim-08- 26, CML112, CML 292, 52303, LM 13, 1336-3, Bajim 06-17, CML563, Bajim 12-6, Bajim 12-6, CML 564, CML 31-1/CM112, V 6642, CML 112 WH 52323, Bajim 06-8, 30R-77, 52060, P358, 52154, 52200, Bajim 08-27 New Line, CML 33, CML 337, HKI1295, CML141 had lowest values for all pathological traits marked as resistant inbreds, whereas thirteen inbreds were reported moderately resistant. Results suggested that the inbreds found resistant to turcicum leaf blight might be utilized in future breeding program. Alternatively, the said promising inbreds might also be used as parents in hybridization in order to transfer the gene for resistance to existing adapted high yielding cultivars.Keywords
