This investigation was carried out to study combining ability along with inheritance of grain yield and its component traits in 100 hybrids of pearl millet which were generated through line x tester mating design using 5 male sterile lines and 20 restorers as parental material at ICRISAT, Hyderabad during Summer, 2018. These hybrids were evaluated in randomized block design with 3 replications in 3 environments during Kharif, 2018 at Rajasthan Agricultural Research Institute, Durgapura (Jaipur). In results, the ratio of variance due to GCA and SCA indicated that predominance of non-additive gene action for all the characters studied except ear girth. GCA effects revealed that parents like ICMA 04999 and ICMA-843-22 (female), RIB-192, RIB-15270, RIB-494 and MIR-525-2 (male) were good general combiners for grain yield and some contributing characters. On the basis of SCA effects the crosses namely ICMA-843-22 x RIB-3135-18, ICMA-04999 x J-2290, ICMA-93333 x RIB-15270 were identified as superior for grain yield and related traits over the environments. Therefore these parents and hybrids are recommended for utilization in development of promising hybrids as well as their use in population improvement.
