Four cytoplasmic male sterile lines were crossed with nine restorers to develop 36 hybrids using line x tester design to study combining ability in pearl millet for twelve different characters and evaluated at main pearlmillet research station, JAU, Jamnaghar in kharif 2018. Analysis of variance showed highly significant differences among the genotypes for all the traits. Thus, the results quantified the considerable amount of genetic diversity exist among genotypes for the different traits under study. Estimates of σ2sca were greater than the corresponding σ2gca for ear head girth, ear head weight, 1000-grain weight, dry fodder yield per plant, grain yield per plant and harvest index, indicated the preponderance of non-additive gene effects. While for rest of the characters, the ratio of σ2gca/σ2sca was found greater than unity, suggested the preponderance of additive gene effects for the express of these traits. Females JMSA4-20172 and ICMA1-15666 and males J-2598, J-2605, 92-SB-18 and 72-SB-18 were found good general combiners for grain yield per plant and also some desirable traits. JMSA5-20175 x J-2598 and JMSA4-20172 x J-2591 manifested significant and high desirable sca effects for grain yield per plant (Table 5) along with significant positive sca effect for atleast one character, with involving at least one poor and one good general combiners.
