Maize being a cross pollinated crop has a higher yield potential compared to other cereals. In the present investigation, 30 full season hybrids (fifteen lines crossed with two testers in Line×Tester) were evaluated for their productivity, drought tolerance and turcicum leaf blight (TLB) disease resistance in the dry tract of Northern Karnataka. The line × tester analysis was carried out to determine the standard heterosis and combining ability in these hybrids with five checks namely Bio 9544, NK-6240 (National checks), CMH08-282 (Zonal check), GPMH-1101 and BRMH-1 (Local checks) under rainfed conditions during kharif 2018 at the Regional Agricultural Research Station, Vijayapur. Among these hybrids, GHVJP5 (GPM-26×CML-451) was found to be better performing for most of the traits followed by GHVJP23 (GPM-686×CML-451); the hybrid GHVJP13 (GPM-225×CML451) was found to be drought tolerant; GHVJP5 and GHVJP12 (GPM119×CM111) were found to be resistant to TLB and GHVJP14 (GPM-225×CM-111) and GHVJP5 were found to be early maturing. These hybrids can be further tested for their proficiency. Among parents, the lines GPM26 and GPM686 were found to be good general combiners for productivity traits. These can be used as parents in the development of superior hybrids.
