Abstract: Combining ability analysis was conducted for yield and its attributes in fodder sorghum. It revealed that variances due to hybrids and parents interaction were significant for all characters. The estimate of variances due to specific combining ability (6²_SCA) and general combining ability (6²_GCA) and their ratio (6²_GCA/6²_SCA) indicated the importance of non-additive type of gene action for fodder yield and its component. The parents, AKMS 14A, 2219A, GFS 3, GFS 4, GFS 5 and CSV 21F were found good general combiners for green and dry fodder yield with one or more yield attributing traits. The SRF 305 reported as good combiner for earliness with green fodder yield and TSS%. GFS 4, CSV 21F, and PANT CHARI 23 also depicted as good combiners for quality parameters like TSS and average combiner for HCN content. The hybrids, 2219A x SSG 59-3, AKMS 14A x SRF 283, AKMS 14A x GFS 3, AKMS 14A x CSV 21F and 296A x PANT CHARI 23 were emerged as most specific cross combinations for green fodder yield per plant.
