In many commercial maize single cross hybrid-breeding programmes, development and/or improvement of superior single cross combinations is a continuous process for which selection of inbred lines is the most critical decision a breeder should make. The advances in quantitative genetics helped many breeders to choose inbreds based through several biometrical methods. Though most of these methods contributed significantly for the improvement of single cross hybrids, there is a need to consider the combined genetic analysis instead of considering these various methods independently, in order to break the present yield barriers, since each of these method reveals the unique ability or genetic potential of the inbreds under consideration. Hence, in the present investigation, the effort was made to study the impact of combined analysis for selection of inbreds based on combining ability, stability and favourable alleles for the improvement of a single cross hybrid. The data generated for this analysis was based on the material consisted of 10 diversified recycled inbreds including the parents of a superior hybrid(IPA34 X IPA21) for which the  improvement is sought. These 10 inbreds were crossed in a half diallel fashion to produce 45 crosses and evaluated in a replicated trial at two locations for two years and analyzed for the combining ability, identification of favourable alleles and stability for the important yield and yield contributing characters. The analysis pattern clearly showed the change in ranking order of the inbreds considering different methods independently and in combined analysis, indicating the need for a comprehensive genetic analysis simultaneously before taking a decision of selecting the right inbred.
