Ten newly developed inbred lines of pearl millet were studied in a set of 10 x 10 diallel cross excluding reciprocals for hybrid vigour. The analysis of variance revealed significant differences among the genotypes, parents and hybrids for all the characters expect for grain yield, number of effective tillers and number of nodes for hybrids. Mean squares due to parents vs hybrids were also observed significant for all the characters expect ear head girth, ear head weight and harvest index. Thus, the study revealed presence of considerable genetic variability in the material studied. High magnitude of parents vs hybrids mean square (except ear head weight and harvest index) indicated presence of conspicuous mean heterosis. The magnitude of heterosis varied from cross to cross for all the characters. Ear head weight and grain yield per plant exhibited the highest heterotic values, whereas, least heterosis was observed for days to flowering. The crosses, SB-220 x D-23, J-2467 x J-2474 and J-2367 x D-23 exhibited the highest heterotic effect and mean performance for grain yield
