ABSTRACT
Studies on combining ability analysis were carried out at three locations during rabi 2015. Observations were recorded for 13 yield and yield contributing traits for 45 single cross hybrids developed using 10 parents in diallel fashion excluding reciprocals. Significance of GCA and SCA variance indicated the presence of both additive and non additive gene action for all traits. The significance of environmental variance indicated the influence of environment on all traits. This indicated that multilocation evaluation is important to assess the combining ability effects of parents and hybrids. The higher magnitude of SCA than GCA variance for all characters indicating predominance of non additive gene action than additive gene action. Among the 10 parents, inbred line namely RML 34, RML 27 and RML 1 recorded superior mean performance for yield and component traits. The parents RML 48 and RML 1 recorded desirable general combining ability for yield and component traits. There was no relationship between per se performance and general combining ability of parents for most of traits. Based on combining ability effects, parents RML 48 and RML 1 can be considered for yield improvement programme.
