Stalk rot in Maize caused by Fusarium moniliforme is the most devastating disease of soil-borne in nature, fungicidal control is ineffective. Hence, testing and utilization of genetic resources resistance against pathogens are cost-effective and eco-friendly means of combating the disease. The current study was carried out and combining ability, analysis was performed using a diallel mating design by utilizing 10 newly developed near inbred lines of maize with varying reactions towards Fusarium stalk rot disease. The proportion of GCA to SCA variance showed that dominant and interaction components were abundant in the exhibition of all characters under investigation. The lines CM202, MAI754, 10878, P8, P7 and P9 were found to be the best general combiners for the maximum number of traits with high gca effects in the positive direction. Among crosses, MAI754 × MAI766, P13 × MAI754, P9 × P8, P13 × MAI754 and MAI329 × CM202 exhibited highly significant sca effects for yield and yield-related attributes. This work led to the investigation of 10 good hybrid combinations with lower sca effects towards FSR viz., MAI329 × CM202, 10878 × CM202, P9 × CM202, MAI329 × MAI766, 10878 × MAI329, P13 × MAI754, P9 × MAI754, P8 × 10878, P13 × 10878 and P8 × 31837 which were superior to the commercial checks Hema and Nithyashree, which needs further evaluation at multi locations and multi seasons to identify superior cross combinations for further commercial release.
